The OneUp V2 Bash Guide combines a top chain guide with protection beneath the chainring. It makes sense on a compatible trail, enduro or downhill bike where rocks and awkward compressions can put the ring in the firing line.
The reinforced nylon bash plate takes the exposed position, supported by an 8mm 7075-T6 aluminium backplate. Three included bash sizes cover 28-36T rings. Up top, the guide flips open without tools, and the crank can remain fitted during installation.
ISCG05 mount; 28-36T capacity with included 28-30T, 32-34T and 36T bash plates.

Keep chain access simple
The top guide flips open without tools. That makes chain access easier, while the compact layout provides retention without the drag of a lower roller.
