Description

Shimano XTR SM-CRM91 Chainring for XTR M9000 / 9020 32TThe Shimano XTR SM CRM91 Chainring features Hollow gear construction for optimized rigidity, lightweight and durability. Key Features: Dynamic Chain Engagement (DCE) is used to hold the chain and help prevent chain jump out. This is achieved by using a broader and taller tooth profile in conjunction with a special hooked leading edge and alternate profiled tooth shaping. This provides superior chain retention, lower driving sound, increased durability

This is a rule of thumb and may not work with some more unusual non-DT Swiss rim profiles

innegra fibres woven into the lay up add extra security to the construction

The ENVE 25mm Layback Seatpost Black is stiff yet it absorbs road buzz and impacts so you don't get that horrible numb bum feeling from saddle vibration
