Product description
The 7075 T651 aluminum we use for these sprockets receives an extra tempering which reduces distortion and provides optimal thickness vs. typically thinner 7075 T6 sprockets 100% machined, no stamping or grinding Optimal tooth thickness results in maximum tooth and chain contact
