1x11 for the masses

Why SRAM’s new X1 transmission will be everywhere next year

When SRAM introduced their revolutionary 11-speed XX1 transmission back in 2012, the scene was set for a distinct change in the way many of us set up our bikes. The unique X-SYNC chainring, with its alternating narrow and wide teeth, was in part the catalyst for this change, removing the need for a separate chain guide when used with a clutch-equipped rear mech. But just as important was the 10-42t cassette, which offered such a

wide spread of gears that it made the front derailleur redundant for many riders.

The system was a success, and only limited by its premium cost and need for a compatible rear hub (because the tiny 10t sprocket was too small for a standard cassette body). With the release of the marginally cheaper X01 group at the end of 2013 and the increase in XD Driver Body hub availability, the scene was set for wider success, with cost the only remaining hurdle. Enter X1…

SRAM’s latest 1x11 transmission has many of the hallmarks of the more expensive groups, including an X-SYNC ring and 10-42t cassette, but uses a new cassette design that mates a CNC machined lower section with a pinned upper, reducing costs. It also gains an all-black coating for extra protection from the elements.

Aftermarket prices start at just over £730 – £80 more than SRAM’s 2x10 X9 and a couple of hundred quid more than Shimano’s Deore XT – but it’s available much cheaper to brands speccing it on complete bikes, bringing 1x11 technology within reach of more riders than ever before.
