American bicycle component manufacturer SRAM entered the electronic components market in 2016. On Feb. 6th, SRAM introduced a new 12-speed hydraulic disc brake, wireless electronic groupset. The new Red eTap AXS expands gear range potentials for triathletes and cyclists whether using a 1x or 2x setup. The SRAM Red eTap AXS is also available with mechanical rim brakes.

SRAM Red eTap AXS is triathlete friendly.

The new AXS groupset brings a wider gear range to e-Tap, carrying the 10-tooth cog over from the company’s Eagle mountain bike lineAlong with the move to 12-speed, AXS introduces greater user-control, a first for eTap. The new wireless electronic group can be programmed to personalize component function and shifting behaviour.

The new levers have slightly updated ergonomics, with more pronounced textured buttons, but continue to use the same eTap shifting logic. If that’s not your style, SRAM has also implemented two new synchronized shifting modes – sequential and compensating. Riders can switch between shifting modes using buttons on the back of the shift paddles, choosing manual shifting or predictive shifting. There are two ports to attach additional controls to the groupset with SRAM’s Blips or Clics eTap buttons. These can be used as sprint buttons or aero shifters, as with the previous generation of eTap, or programmed to control other AXS devices across the system. All of this can be programmed used SRAM’s new mobile AXS app.

The new mobile AXS app also shows the charge level of the components individually, software updates and set maintenance reminders.

Going 12-speed has many implications for riders. With offering a 10-tooth sprocket on the cassette the available gear range for riders has been widened. There is also a slightly more gradual gear progression between cogs on a 10-28 cassette with five one-tooth jumps, from 10t up to 15t SRAM will offer 10-26, 10-28 and a 10-33 rear cassette.

The cranksets will be available in both 1x and 2x pairings. To achieve similar gear ratios currently available on 11-speed groupsets, SRAM will offer a 50/37, 48/35 and 46/33 cranksets. While the 2x offerings sound small, combined with a 10-tooth sprocket shifting rations are similar to what is currently available on 11-speed groupsets. For those interested in running a 1x system, SRAM will offer two aero cranksets, a 50-tooth and 48-tooth. Cross and adventure racers will find the range they need in the 46, 44, 42, 40, 38 and 36 options.

To accommodate the new gearing, SRAM has revised their front and rear derailleurs. The new SRAM Red eTap AXS rear derailleur only comes in one cage length that is compatible with all cassettes for both 1x and 2x setups. The derailleur has bigger pulleys and ceramic bearings to achieve smooth and quiet shifting.

The front derailleur has been designed to accommodate the trend of running wide tires. The design makes space for increased rear-tire clearance so installing a 2x setup on an adventure bike will be not a problem. Both derailleurs are compatible with existing SRAM eTap batteries.

The new chain has an asymmetric design that is flat on the outer side and it has larger rollers. This is intended to make the chain last longer and have more strength. The chain is also narrower to accommodate the extra cog. A new chain tool, the Park Toll CT 3.3 will be required to install the new chain.

SRAM’s also unveiled Quardq DZero integration for the new drivetrain. The power meter is fully integrated into the crankset. This means once the chainrings wear out, the power meter has to be replaced. That said, SRAM claims its new chainrings will last up to 50 per cent longer than the companies existing 11-speed chainrings.

With a smaller BlipBox, it easily integrates into aero bars or Zipp’s new Vuka Aero bar. Vuka Aero is a lightweight aero bar that easily fits the SRAM eTap AXS BlipBox within the center cap, keeping it out of the wind and out of sight for a clean cockpit.
