Specially designed for use with Hope’s 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  Boost type mountain bikes.
