Make your Classic or ISO Disc rear hub super tough by replacing your stock aluminum driveshell with this Stainless Steel Driveshell. Stainless Steel driveshells are usually only needed when you use a cassette that has individual cogs that aren't clustered, or on a tandem. It adds 48 grams compared to the aluminum drive shell.
Note that the Chris King spline tool or the Chris King hub service tool kit is needed to move the bearings & internal parts into this drive shell.
Once the internals are in place, installing your driveshell is easy. Other than a standard hex wrench, no other tools are needed. Check out the VIDEOS and PDF instructions on the Chris King® website.
