Profile Racing
Bottom Bracket
Bearing System
for Splined Cranks
at Yellow Jersey

Bicycle parts don't get much more specialized than this, but when you need one, you need one of these!
Profile Racing ( not to be confused with Profile Design, Bill Powers' triathlon equipment company, although we carry their equipment, too) make the ultimate bearing system for splined twenty inch type cranks. If you have a Redline Flite Crank with bearing woes, here's exactly what you need. Profile uses two bigger tougher bearings in a self-aligning cup set that just plain works better. This photo says it all.

Yes you need the wrenches too
