Designed as an extra light weight sprocket that can take one hell of a beating. SPECS - 5/16" thick 7075 T6 CNC machined aluminum - Heat Treated drive splined insert for 19mm 48 spline cranks - 1/8" wide teeth - Available in Bolt Drive SIZES - 19mm spline drive - 25T, 28T, 30T   WEIGHT - 25t: 2.6oz/73g - 28t: 3.0oz/84g - 30t: 3.4oz/95g INFO It is made of 5/16" thick 7075 t6 aluminum. The design went through 6 prototypes of finite element computer analysis, real world testing, and laboratory testing. The spokes of this sprocket are tapered and I-beam shaped putting material where it’s needed and taking material away where it is not needed. All of this work created the highest strength to weight ratio sprocket out there. Every single detail has been thoroughly thought out. Many all nighters have put into designing this thing! This sprocket uses Spline Drive a technology I developed when trying to improve the way sprockets are attached to cranks. We did not patent the design. (oops!) Alt
