Yep, thanks Trek and Gary Fisher and Shit-mano for introducing another semi-useless, more annoying technology to "improve" our bikes.
You call it BB90 with Press-fit bearings! I get how wider is better for bottom brackets. 2 Semesters of college physics plus tons of auto work as a kid helping my old man repack bearings during the summers when bored at his work. So I do get why this is a somewhat improvement. What I don't get is what MORON said hey lets put in non serviceable, not easily replace bearings that must be pressed in!
On my old bike with external bb I could pull the cranks and full clean each cup/cap set in about 30 minutes and re-install. If I had the interest with the right tools I could even open the bearings and re-grease them. (Or if pimped out with CK BB I could use the Fittings and do it very quickly).
I did my best to "service" the bb short of breaking out a chisel and investigating how REALLY dumb this design is. I wiped all the accumulated crap off the shell, the bearing faces the interior area's. I re-greased the back of the bearings that had some REALLY crappy grease. I couldn't find my high grade synthetic so I used good ole polypro from Park Tools. Re-ass-embled, and went out for a 40 minute test ride. No signs of creaking from the BB Area. Lots of bugs in my eyes though, gotta remember to wear glasses if going out anywhere near water near dark these days. UGH.
Hmmm might have to spend some money with Park Tools again in the near future
Don't believe the Hype!
