Description
Ultimate Chain Retention and Bash Protection
The OneUp Components Bash Guide is designed to eliminate dropped chains while protecting your chainring from the hardest impacts. Developed with input from professional Enduro World Series (EWS) racers, this lightweight and durable guide provides reliable chain retention and serious protection for aggressive trail riding, enduro, downhill, and bike park use.
As modern mountain bikes continue to become lower and slacker, chainring protection has become increasingly important. The OneUp Bash Guide combines a reinforced nylon bash plate with a strong 7075-T6 aluminium back plate to withstand heavy impacts while keeping weight to a minimum.
Featuring a simple installation system, tool-free upper guide adjustment, and compatibility with a wide range of chainring sizes, the Bash Guide offers maximum performance without unnecessary complexity. Thanks to modern clutch derailleurs, it removes the need for a lower roller, reducing drivetrain drag while maintaining excellent chain security.
Whether you’re racing enduro, riding technical trails, or hitting downhill lines, the OneUp Bash Guide provides the confidence to push harder without worrying about chain drops or chainring damage.
