Hope Spiderless Boost Retainer Ring

Hope Spiderless Boost Retainer Ring

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.
