Chain Ring จานรองโซ่ ใบจาน Sram XX1 32T

This is a SRAM XX1 X-Sync 76mm BCD Chainring for XX1 cranks. Replace a worn out ring or swap to change gearing without the need to remove the cranks. X-SYNC™ technology delivers complete chain control, as each tooth’s thickness is CNC-machined to fit better into the chain’s inner and outer links. The X-SYNC™ chainring is constructed of 7075 alloy and is available in 6 different ratios, giving you the ability to dial in your gear range to your ride.

Features: 

• Must be used with SRAM 11-speed chain for 1 x 11 
• Tooth profile alternates thickness by inner and outer links for maximum chain control
