Renthal - Renthal SR4 4-Arm 104BCD Chainring - SR4 4-Arm 104BCD Chainring
Renthal SR4 4-Arm 104BCD Chainring
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.
The Renthal SR4 chainrings are legendary in their stiffness and longevity. The 5mm thick Ultralite™ chainring uses an I-Beam section tooth support bed, for the highest possible stiffness at the lowest possible weight. CNC machined from 7075 T6 aluminium , the hard anodised surface treatment massively increases the lifespan of the chainring.
Renthal® SR4 chainrings are designed to ride faster, jump further and last longer.
