A narrow-wide chainring does a lot of the work, but a top guide adds another line of defence when the bike is bouncing through rough ground. The OneUp V2 Chain Guide provides that extra chain control in a 40g ISCG05 package, without a lower roller.
The upper guide flips open without tools for access to the chain. Installation and adjustment use a 4mm hex key, and the guide can be fitted without removing the crank. It supports round or oval rings and Boost setups within its adjustment range.
ISCG05 mount; 26-38T chainring capacity.
7.5mm chainline adjustment.
7075 aluminium backplate and glass-reinforced thermoplastic upper guide.
Black guide piece and stainless-steel hardware.
Not compatible with the current Trek alloy Slash or Gen 6 Fuel EX carbon/alloy frames, Ibis Ripmo or Ripmo AF, or V5 Commencal Meta SX. Check your exact frame and generation before ordering.
