A set of three for the price of "another" brands outer only. The outer is hardened CNC machined Aluminium, looks the biz and will last ages due to the hard material withstanding wear. The middle and granny are made from 6000 series alloy to keep the price sensible. Harder than the usual 2000 pressed alloy its life is as good as decent quality replacements.
Fully ramped and pinned to allow for smooth shifting.
Coming in the new year is a larger range of spec, including cheaper steel rings and Full CNC ringsets.
