Profile Racing’s Legacy: Week 25, 1993.

The Trifan Becometh!

In 1993, Corey Alley decided to add a second solid chainwheel to Profile’s gamut. Having a low-rider S-10 with 3-spoke, directional wheels, he was inspired to design Profile’s Trifan Sprocket.

This was the first sprocket manufactured by Profile using a 3-axis mill, which was able to produce our first 3-dimensional sprocket.


Only available in sizes 39t through 48t at its peak, and only available in a high polish.

For our 50th anniversary, we’ve done a VERY low number of 40t Trifans in a collectable Gold anodize.
