Review: Women’s Bontrager winter wear


Bontrager B2 long sleeve base layer – $85

When riding in cold and/or potentially-wet winter conditions, layering and dressing appropriately is of utmost importance. That being said, I usually opt to get my upper body base layers from the thrift store, discarded Dri-FIT tops from New Years resolutionists that do a fine job of wicking sweat underneath my ever-trusty Dirt Rag woolie. While this method has worked for me in the past, I will say that this Bontrager B2 shirt is starting to spoil me.

Wool is king when it comes to regulating body temperature and keeping you warm even when wet and sweaty. Unfortunately, I have sensitive skin and trouble wearing wool directly against my body. That was my initial concern and skepticism when I got the B2 – would I even be able to wear it without being uncomfortable?

I’m happy to report that this shirt has just enough polyester in it (35% to be exact) to keep the prickly fibers at bay and make it tolerable–even comfortable–to wear all day. Another bonus: Even after a long, sweaty bike ride, the B2 doesn’t hold odors well, so I was usually able to get several uses out of it before washing.

The B2 sports a slim cut and is just a tad longer in the rear than the front for the best fit while on the bike. It’s not overly stretchy, but offers enough give that it’s comfortable through a full range of movement and for some variety of different body shapes.

I wore it both as a standalone shirt and as base of any number of layers, and found that it was comfortable worn by itself or with a thin windproof vest in temps ranging from the mid-30s to around 50 degrees Fahrenheit, while colder temps warranted some sort of full outer layer on top.

The Bontrager B2 has become a favorite go-to this winter. The body temperature regulation that the wool/poly blend offers makes it a solid choice for a wide variety of temperature ranges–or when you aren’t sure what the weather will bring. If I can only bring one base layer shirt on a trip or bikepacking overnight, this is the one I’d choose.



Bontrager Meraj S2 Softshell tights – $125

These tights showed up just in time for a two-week stretch of extra cold weather here in Pennsylvania. With highs in the single digits or teens for several weeks on end, I appreciated having such a warm and windproof layer.

The Meraj comes in two different weights – the S1 is meant to be used in above-freezing conditions, while the S2 was designed for below. And when Bontrager says below freezing, they mean it. I wore these on several road and gravel rides when temps were in the 20s and was plenty warm. On the trails, my legs were toasty with just this single layer of pants down into the mid teens.

A softshell material on the front of these tights is windproof and water resistant, while stretchy panels of fabric on the rear ensure optimal fit and ease of movement. There are also strategically-placed thermal fabric inserts and a top-to-bottom fleece lining that provide added warmth.

The wide waistband is comfortable and a drawstring allows for cinching should it be a little too loose. I found that the size small S2s fit like a glove on my 27-inch waist/33-inch hip – no digging in from the waistband and no tightening needed. The bottom cuff of the Meraj S2 tights features a zipper closure, zipper garage to keep out the wet, and silicone ankle grippers to keep the cuffs in place.

Overall, I’ve been really happy with these tights. They fit well and are comfortable both standalone or with a pair of baggies over them for mountain biking. If you regularly ride in below-freezing temperatures and damp or windy conditions, I think they are worth the investment. If most of your winter bike adventures take place right around freezing or slightly above, I’d check out the Meraj S1 tights instead, as the beefiness of the S2 is probably unnecessary.


Both the Bontrager B2 top and Meraj S2 tights come in sizes XS-XL and are fairly true to size based on this size chart. However, if you’re on the edge between two sizes or want a slightly looser-fitting garment, I’d recommend bumping one size up for these particular pieces.


Four rear lights for summer nights (and beyond)

By Jeffrey Stern 

Although the longest day of the year has passed, there are plenty of late summer nights in our future. When I think of summer, I think of big bike adventures, often planned to be done around dinner time, but also just as often pushed well past twilight. Only for pure enjoyment sake and because you can never say no to one more new trail or road when there’s still a bit of light left in the sky, right?

Too many times this leads to riding home in the dark, sharing lights with a friend or two. The classic, one of you has a front light, the other a rear and the third has neither so they sit in the middle of the reduced peloton on the midnight express through the city streets and back safely home…

Why not nearly guarantee your visibility with a high-quality, USB rechargeable light that will last you for seasons to come? Trust me, your family and tail-wagging pup will thank you when you walk in the door safely all summer long.

The Lezyne Zecto is a high visibility three-LED, 20 lumen light with a built in motion detecting system featuring six different flashing modes. This light will automatically turn off after three minutes of inactivity. With a machined aluminum faceplate and lightweight, yet durable composite matrix body the Zecto it is as sturdy as functional. At a svelte 47 grams, this micro-USB rechargeable light also has a versatile clip-on system for easy attachment to your seatpost, pannier or backpack and only costs $50.


At 65 lumens, Trek’s Bontrager Flare R Tail Light features a CREE LED that can reportedly be seen from over 2km away day or night. With two night and two day modes, the 270-degree visibility offered by the Flare provides the ultimate safety options for all-day riding. A unique battery save mode kicks in at 5% life to get you home safely in that last hour of your ride. The quick connect bracket and 16 degree offset makes attachment and adjustment a breeze for this features loaded $60 USB rechargeable light.


If you have a little more to spend and are looking for the increased safety of a built in camera, look no further than the Cycliq Fly 6 bike camera. The Fly 6 is a waterproof rear light with 720p HD camera in case of an on-road accident. At just over 100 grams with a 100-degree view, this light/camera combo watches your back by recording in 10 minute intervals so you can ride stress free. Run time is rated at six-plus hours and the Fly 6 comes with an 8GB Class 10 MicroSD card as well as USB cable. Substantially more than most rear lights at $140, it’s well worth the investment if your rides take you on the narrow shoulders of busy roads frequently, for increased peace of mind for you and your family.


The Cygolight Hotshot 50 delivers a lot of power, to the tune of 50 lumens, in a small and affordable package. It’s lithium-ion battery is charged lightning quick via USB and the six different light speeds are user-adjustable. With 500 hours of use available on a single charge and costing a cool $30, this might be the best bang-for-your-buck rear light option on the market.

Bontrager encourages daytime running lights for bikes

They’ve been on motorcycles forever, and more recently cars have adopted them too, so why not bikes?

Daytime running lights can significantly improve your visibility on the road, Bontrager says, and the brand is touting its new line of front and rear bike lights as specifically designed for both day and night use. Bontrager says it is just the first step in a sweeping line of products to make cycling safer. Since safety concerns are the number one impediment to get new cyclists out on a bike, we think it’s a great move.


Bontrager says the data it has collected show accidents decreased 25 percent after automobiles adopted daytime running lights, and cycling accidents could be reduced by a third. Because 80 percent of bicycle accidents occur during daylight hours, the brand feels there is a big opportunity for positive change. Just a few days ago I was driving on a twisty mountain road and the cyclists on the road were extremely hard to see as we went from bight sunlight into dark shadows and back again through the trees. A bright light really would have helped.


Optimizing visibility is more than just raw lumens, Bontrager says. The key difference is being seen versus being noticed. It says its line of taillights have blink patterns that are specially designed to be more conspicuous during the day than just a steady blink. It says some are visible from up to two kilometers away.

Review: Bontrager Old Man Winter boots

Cycling-specific, cold-weather boots have long seemed like a luxury item to me. That changed when I decided to get a fat bike for riding on snowy trails and decided to suck it up and pedal around my Colorado hometown all through winter. Suddenly, no overshoe was warm enough and no casual snow boot stiff or snug enough. After spending a few weeks with Bontrager’s brand-new and rather svelte-looking Old Man Winter (OMW) boots, I am completely sold on the idea.


If, like me, you have Raynaud’s syndrome (the cold-weather narrowing of the blood vessels in your extremities) keeping your fingers and toes warm sometimes seems impossible. The OMW helps allay that with a fleece-lined, removable inner bootie packed with 200 grams of 3M Thinsulate insulation. The stretchy outer boot is made of waterproof, breathable OutDry material and features sealed zippers. The inner bootie has a drawstring-type closure. Paired with two outer Velcro straps, the boots allow for a very snug fit and offer plenty of adjustment.

My only minor complaints are that it can be difficult to zip the ankle gaiter over the plastic pull tab on the laces and, if you don’t manage to raise the zipper completely to the top of the ankle, the pedaling motion will push it down.



The liner is removable. I think the shoe would be much too roomy and not as comfortable to ride without, but I’m glad I can wash it. A rough material on the heel works as advertised to prevent the liner from slipping around inside the boot. The sole of the liner is not protected with any kind of grippy material, i.e. it’s not made to be removed and worn around your house as a slipper (which I would totally do).

Because of my Raynaud’s, I have been wearing these boots in temperatures as warm as 40 degrees, which is honestly much too hot unless you’re casually cruising short distances. Down to 30 degrees, my feet stayed plenty warm on a difficult fat bike ride through deep snow with only a thin pair of Bontrager’s Profila Merino wool socks. That particular ride involved a lot of grumbling and tramping around in ankle-deep snow without a hint of cold in my toes. The elastic pull tabs that tighten each boot’s ankle did their job, keeping snow out as I pushed a 40-pound bike up steep, un-groomed trails.

These boots really shine in temperatures down into the teens and twenties with a thick wool sock, particularly if you’re exerting yourself. I can’t comment on their sub-zero performance as Colorado is experiencing a fairly warm start to winter.



Sole stiffness is a 6 on Bontrager’s scale (the highest stiffness on any shoe the company offers is a 14). Walking around and driving are comfortable for short distances. I didn’t feel any bending nor did I feel the cleats poking through when mashing the pedals on steep, challenging trail climbs. While they might not be rigid enough for skinny-tire go-fast types, I am plenty happy with them on cold, wet road rides and they offer enough flex for all-day adventures that might involve espresso stops or setting up a campsite. Traction is good on dry land but, as to be expected, the lugs will get snow-packed if you’re trudging around in powder.

The boots come with substantial cleat covers for the flat-pedal community. If you plan to see more serious snow or ice action, the sole allows for two toe spikes (not included) and each boot has a gaiter hook just below the toe-box strap. Another nice touch are Velcro tabs on the rear ankles of the shoes that are designed as a place to put small red lights.



I had to order a full size larger than expected in order to accommodate anything other than a liner sock and to get the zipper to close around my ankle when wearing tights, but I’m grateful to have room in the nice, wide toe box for super-thick ski socks.

Actual weight is 1,205 grams (pair, size 43). If you don’t think in grams, just know that they surprised me with their lightness when I pulled them out of the box. They don’t feel clunky on my feet and almost look like regular shoes if you’re cruising around town and pull your pant legs over the ankles.

If you’re planning to spend several months riding in sub-freezing temperatures—whether you’re commuting or mountain biking—consider these boots. I have enjoyed their warmth, comfort and adjustability, and no longer see a well-made shoe like this as just a luxury.

Price: $300



Review: Bontrager Flare R Tail Light

Seven years ago, I rode my bike across the country with nothing but a $13 red bike light strapped to my seatpost. It wasn’t very bright and functioned more as hopeful optimism than a true safety device.

Now I’m pleased to see that daytime running lights for bikes are being taken more seriously. The Bontrager Flare R puts out 65 lumens in daytime random burst mode—an impressive level of brightness that completely outdid every other rear bike light on the last group ride I was on. Daytime steady mode is more modest 25 lumens. Night time output is 5 lumens in steady mode and 65 lumens in burst mode.

Flare R-1

What’s a lumen? I read somewhere that lumens are to light the way gallons are to milk; it’s a measurement of how much light is given off. A standard 25 watt lightbulb (the ones that are difficult to find nowadays) gives off about 220 lumens. Car brake lights are around 350-500 lumens.

Anyway, Bontrager claims this light can be seen from 2 kilometers (1.2 miles) away during the day and 5 kilometers (3 miles) at night. I couldn’t find a stretch of road to test that, exactly, but I was able to find out that if you look directly into this light while standing next to your bike, it will mess up your vision for a few seconds. The Flare R also has decent side lights and claims 270 degrees of visibility. Its four modes are easy to toggle through via a large button on the top of the light. That same button features a status LED light that displays battery life.

Flare R-2

The light easily unclips from the stretchy rubber seat post mount and charges using a micro USB cable (included). If the light gets down to 5 percent of life or less, it will need two hours to full charge. Thanks to not needing tools to mount this light, it only takes a few seconds to swap it to whatever bike you’re about to go ride and means there’s no reason not to. I’ve even stuck it on my mountain bike when riding from home to the trail.

Battery life is a claimed 5.75 hours in daytime flash, 23 hours in night time flash, 4.25 hours in daytime steady and 21 hours in night time steady. I left the light on in the house and hit those numbers almost exactly. When the battery dips below five percent of life, the light will automatically switch to flashing in a low-energy mode to conserve its life should you still be far from home.

Flare R-3

When mounted using the bracket with rubber strap, the light swivels easily. It’s too small to fit around a large aero seat post (sorry, triathletes) and a bit too large for super-skinny road bike seat stays, if that’s where you’d rather mount it. But Bontrager includes a seat pack clip for the light, which is much appreciated by this short rider who often has no room left on a seatpost when a saddle bag is attached.

Finally, the Flare R is neither bulky nor heavy (36 grams), so weight weenies rejoice. At $60 it’s not cheap, but the construction feels hearty and has so far proven to be weather resistant. Bontrager says it focused on a daytime taillight because studies show that 80 percent of cycling accidents occur during the day. So even if you don’t get this rear red light, consider getting one.



Bontrager releases new taillight designed for daytime use


Cyclists all know that bight lights and visible clothing can make them more visible to drivers and thus safer against collisions, and Bontrager’s newest tail light is designed to cut through the distractions of daylight driving and make it even more difficult for drivers to miss seeing cyclists ahead. According to studies, 40 percent of cyclists’ collisions with cars are from being struck from behind, and having a tail light on during the day makes perfect sense.


The new Flare R light is a USB-rechargeable, 36 gram LED light that pumps out 65 lumens—that’s more than a car’s tail light. Bontrager studied flash patterns and intensity to choose exactly the one that will make it most visible to drivers in the clutter of urban lighting. Bontrager says it is visible in daylight from more than a mile away.


The Flare R has four distinct flash patters: two for daylight and two for night:

  • Day Flash mode will utilize all 65 Lumens in a strategically placed random flash pattern designed to draw a motorist’s eyes. Fully charged run time is 5.75 hours.
  • Day Steady mode uses 25 Lumens of steady illumination and is great for group rides. Fully charged run time is 4.25 hours.
  • Night Flash mode uses an irregular flash pattern punctuated by short pops of increased intensity. Fully charged run time is 23 hours.
  • Night Steady mode provides 5 Lumens of steady light great for consistent nighttime visibility. Fully charged run time is 21 hours.


One of the downsides to battery powered lights is that when the battery dies, you’re out of luck. The Flare R has a built-in safety system, whereby when 75 percent of the charge is used the LED indicator light on the unit turns from green to red. When it reaches 5 percent of its charge it automatically puts itself into a safety mode and dials back the intensity to give an extra hour or two of run time, just enough to get to safety. A full recharge takes only 2.5 hours.

The new Flare R light is available now in Trek and Bontrager retail stores for $60.



This Just In: Bontrager Ion 700 headlight


Daylight hours are shrinking, but for many cyclists that doesn’t mean our miles have to follow suit. Finding a decent and affordable rechargeable headlight is getting easier, and the five-mode $99 Bontrager Ion 700 is one to consider.

The high-power Cree LED kicks out a full 700 Lumens, which Bontrager says will run bright for up to an hour and 45 minutes.

What’s Cree? It’s the company that first brought the blue LED to market in 1989, and today Cree’s XLamp LEDs exceed industry standards for brightness and efficiency. According to the company, Cree XLamp LEDs were the first ‘lighting-class’ LEDs – LEDS bright enough to be used in general-illumination applications, such as desk lamps, ceiling fixtures and street lights.

In addition, Cree’s extensive line of high-brightness LEDs are also introducing new performance levels to outdoor video displays and decorative lighting. Seems like Bontrager did some proper vetting when deciding on LED technology.


Five modes

If you don’t want oncoming traffic to flash their high beams, bump it down to 450 Lumens for three hours of runtime, or 200 Lumens for six hours, 45 minutes. There’s also a 50 Lumen flash mode and an ‘irregular strobe’ that comes in handy for daytime use. Dual amber ‘windows’ bookend the face of the headlight, which is primarily made of metal, not plastic. A full micro USB recharge takes up to five hours.


A clever rubber bracket provides 20 degrees of adjustability, and fits handlebars from 22.2 to 31.8mm in diameter.

In Print: Mushroom Foraging with Keith Bontrager


Editor’s note: If you own a Trek, Gary Fisher or LeMond bicycle, chances are a former motorcycle racer and tuner from Santa Cruz, California had design input on the tires and components on that bike. Not only is Keith Bontrager a whiz with engineering, he’s also an expert on mushroom hunting. We asked him for some advice on proper foraging tips to find tasty fungus for the kitchen.

By Keith Bontrager

I don’t have to tell you that there are a lot of good reasons to ride your bicycle: transportation, sport, fitness, head clearing, looking stylish, an adrenalin fix, pub crawls, whatever. They’re all good. One of my favorites is finding dinner.

The thought that comes immediately to most people when I mention wild mushrooms is “you’re insane” (and that’s certainly true in some respects) – there is some edge to this sort of thing. But with a little care you never need to put yourself in jeopardy. Here are some solid rules:
