RNC Titanium Universal Spline Adapter - 19mm, 22mm & 24mm

I have the RNC Uni Ti sprocket (4mm thick), so I needed to sand down the Ti adapter (about 5mm thick) to fit. If run stock, it will protrude out too much, taking extra spindle space, and messing with the chain line. It all depends on your sprocket thickness. Otherwise, it works great, and half the weight of steel.

If you have a RNC Ti Sprocket, and a RNC Ti bottom bracket, you will need one of these. Cool Ti piece. Ryan has it together.
