The composite material of the sheave body improves its wear resistance, resulting in quieter and more efficient operation. Compared to traditional aluminum sheaves, it significantly extends the life of both the sheave and the chain.Narrow Wide Tooth:- The narrow and wide tooth design allows the sheave to better engage the chain, significantly improving operating stability.Specifications:- Compatible with: SRAM Red XPLR AXS, 13-speed- Use: MTB- Teeth: 14T- Upper sheave - 16T-Lower sheave- Material: Pulley body: PA+GF composite material- Bearings: Stainless steel- Weight: 13 g- Upper Idler (Steel) - 33g- Lower Pulley (Steel)
