New tooth profile option compatible with Shimano 12SPD drivetrain systems, a narrower tooth profile designed specifically for use with Shimano 12SPD chains. This differs to our Standard chainring and is now offered alongside Standard Retainer Rings. Specially designed for use with Hopes Boost compatible mountain bike (MTB) cranksets, this Spiderless Boost Retainer chainring adopts the direct mounting system and the narrow/wide tooth design.
This tooth profile results in outstanding chain retention over the toughest trails, removing the need for a chain device on your bike. Made from CNC machined 7075-T6 Aluminium, it runs quietly, reduces drag and it's ready for use with the wider chainline on a Boost type mountain bikes.
