Outside of testing bikes, Tom competes in a wide range of mountain bike races, from multi-day enduros through to 24-hour races in the depths of the Scottish winter pushing bikes, components and his legs to their limits. Any combination that is a go will consistently deliver a high level of performance, in keeping with the view of the manufacturers, while no-go will signify an incompatibility where there is an obvious shortcoming in the operation and/or performance of the system.

Mixing and matching cranksets and bottom brackets is a completely different matter that depends upon the specifications for the frame and the crank axle. 0000015649 00000 n Therefore, you need to compare specific rotational bits of the NX and GX drivetrains to know if that 15% weight difference is universal.

When the American drivetrain brand went beyond the front derailleur in 2012 and ushered in the 1x standard, it spawned a new era for off-road cycling. As a consequence, the rear derailleur limit screws and cable tension may have to be reset when swapping wheels. For the best experience on our site, be sure to turn on Javascript in your browser. In addition, Campagnolos chains differ from Shimano/SRAM in overall width, and the company uses variable spacing for its sprockets (Shimano/SRAM cassettes have uniform spacing).
