it's hardly a proprietary tool. it's just a splined cartridge bb tool.I have bikes with Raceface and Trivativ cranks. I think Trivativs are better than RF. At least I don't need proprietary tools to replace my Truvativ chainrings.
so? I couldn't tell you how many bb tools I have after 20yrs of accumulating them. I'd have to go out into the garage and count them. buy a different brand of bb, chances are you have to buy a new bb tool. buy a frame with a different bb shell spec, chances are you have to buy a new bb tool (unless you were smart/lucky and bought a tool that'll handle more than one bb type earlier).Didn't know that. Still is a tool that I don't have as I never needed. Looks like will have to buy one, just for the crank... :madman:
