Renthal SR4 4-Arm 104BCD BMX Race Chain-Ring

Renthal SR4 4-Arm 104BCD BMX Race Chain-Ring

SR4 Chain Ring (Single Ring 4 Arm, 104BCD). Renthal's chainwheels are precision CNC machined to extremely tight tolerances to give the ultimate combination of strength and light weight. The 7075 T6 aluminium alloy chainwheels are 66% lighter than steel, yet incredibly durable. Their advanced tooth profile, concentricity and accuracy of fit provide maximum power transfer and long-life. Renthal's combination of a very high strength base material and an exceptionally hardwearing surface result in significantly increased chainwheel life.
