Compatible with all 10 speed transmissions, the V-Drive triple gives you a robust and reliable crankset with a big gear range. For durability, the inner ring is made from heat-treated chromoly – with fewer teeth to spread the load, small chainrings tend to wear faster so they need to be harder. Middle and outer chainrings are both 7075 aluminium, with the outer being CNC machined. You can opt for close-ratio 42/32/24 rings or conventional 44/32/22. Both BB30 and MegaExo versions are available.
