Acros’ A-GE hydraulic shifting group drops the front derailleur for their new 1×11 system, making it the lightest shifter/derailleur combo we’ve seen.
The rear mech’s upper knuckle has been better optimized and slimmed down, which saved weight and looks better. Other changes were made to keep up with trends, too, and they’ve just finished brand new hubs…
It also gets a elastomer damping system inside the pulley cage pivot to keep the chain from bouncing. Not exactly a clutch, but same idea. The wound spring that’s visible here is the tension spring.
Entire system weighs just 288g wth hydraulic fluid inside and everything. Max 42T cog, and it’ll work with SRAM or Shimano cassettes.
The shifter can push up to four inboard shifts and two outboard. Available with a matchmaker mount to fit with SRAM / Avid brakes. Retail for the group is €849.
New road hubs with use a ring ratchet system much like DT Swiss’ but with 38 teeth.
What makes it different is the ability to change the amount of tension between the two ratchet rings. Three springs on the backside slot into three different sets of holes, all with different depths. Moving it between them let’s you customize the loudness of the hub, but performance is the same. So, stealth mode or “look at me!”
They’ll work with all common road axle systems with end cap changes.
Inside them all, including these new mountain bike hubs, is a larger 19mm axle to make them a lot stiffer.
They get a new preload adjustment cakes The Clam. It’s a sandwiched system that uses ramps to spread them and reduce play. Tighten the screw and it spreads them more to take up any slack in the system.
These new design features spread to XC, freeride, Boost and single speed mountain bike hubs, too.
They can be ordered as prebuilt wheels, too, with Stan’s Crest, Ryde Race Trail or WTB Asym i29 rims. Available in XC, trail/enduro and gravity builds.
