SRAM to release clutch rear mech? Photo reveals they are

Share:

Take a look at the photo above. Look real close. Spot anything different?

SRAM released this photo on its Facebook page, and those with 20:20 vision will spot the unusual looking rear mech. While the company hasn’t officially released any details about what sets it apart from regular SRAM mechs, we can deduce that it is most probably a clutch-style rear mech, as pioneered by Shimano with its XTR Shadow Plus last year.

The Shadow Plus has been one of the most well received products of the past year. It uses a one-way clutch to keep the chain tension high, preventing the mech from swinging forward. This has obvious benefits of eliminating chain slap, preventing the chain falling off, especially useful with 2×10 and 1×10 setups.

It’s likely that Shimano will quickly trickle the technology down the range. And with this released photo, SRAM is sending out an answer to all those people who have wondered if the company will offer a similar product.

    “…has obvious benefits of eliminating chain slap, preventing the chain falling off, especially useful with 2×10 and 1×10 setups”

    I don’t really get it, in the above photo the bike has 1×10 with chain device. I can see there being almost zero chance of the chain falling off and very little chain slap anyway. 2×10 I can understand

    You could feasibly remove most the chain device with a clutch-style rear mech, therefore saving some weight. They’re that good at stopping the chain slap about, a chain device is mostly redundant

    The question I’d like to see answered is whether the extra force on the derailleur as a result of the clutch will result in more derailleur hanger and derailleur failures. Also does it make changes to gear where the chain gets longer feel heavier?

    If the clutch/damping device increases damping with the speed or acceleration applied to it the gear changes, which happen a lot more slowly than chainslap, could feel the same, but the extra forces on the derailleur hanger are the big question.
