Riders desiring hydraulic disc brakes on their road bikes can now get flat-mount discs from Shimano at a Tiagra price point. Previously, Shimano only offered this technology at Ultegra and 105 levels.
The BR-RS405 system uses 140 or 160 mm rotors with Shimano’s heat-dissipating ICE technology. Shifters feature 10 mm of reach adjust and will accommodate 10-speed cassettes.
Pricing has not yet been set. Aftermarket availability is predicted for July 2016.
Campagnolo recently announced a new, mid-level groupset called “Potenza,” which means power, intensity and strength in Italian. The 11-speed Potenza groupset benefits from trickle-down technology off Campy’s highest-end carbon groupsets: Super Record, Record and Chorus.
The aluminum crankset and rear derailleur are designed in the same manner as the carbon components of the Super Record group, with the only reported penalty being weight, not performance. Also trickling down are the ergonomics of the brake hoods and levers. The thumb paddle shifter also allows you to upshift three gears with one click, but only one gear at a time shifting down.
Cassette options include 11-27, 11-29, 11-32 and 12-27. The 11-32 is new for this line, offering a wider range. Crankset chainring options include 53/39, 52/36 and 50/34.
An all-silver groupset will also be available. Potenza will replace Campy’s Athena components and is intended to compete with Shimano Ultegra. Price was announced at just under 900 Euros for the kit.Tweet Print
You can now run a 1 x 11 setup with hydraulic brakes using SRAM’s Apex 1 groupset and choose whether or not you want flat- or drop-bar shifting.
The long-cage rear derailleur ($74) will accept a 10- or 11-speed cassette with up to 42 teeth. The crankset offers ring sizes with 38, 40, 42 or 44 teeth, and 170, 172.5, and 175 mm crankarm lengths. The crankset is compatible with 130mm, 135mm and 142mm OLD frames. The GXP version is $116 and the BB30 version is $151.
Snag flat-bar shifers for $27 each or hydraulic brake levers with intergrated SRAM double-tap shifters for $199 (left) and $249 (right). The PG-1130, 11-speed, 11-42 tooth cassette retails for $79. The PC-1110 chain rounds out the kit at $14.
SRAM Apex 1 should be available by June.
