Madone and Campy UT crankset

[Kingfisher]

Gonna take the 9000 off my Madone 7 and replace with a newer (2 year old) lightly used Super Record group.

Crankset seems to be an issue with the stinking BB90 bottom bracket.

I see there is a kit you can buy and install...anyone ever done this install, fairly easy or complicated?

Info here, just google BB90 Campagnolo B.B. adapter.

Don't forget the Loctite 609 and primer, and get a proper press (not the wood dowels in the video).

And here is note from Trek (posted on VeloNews http://www.velonews.com/2013/06/bike...helmets_290405) with link to service manual.

Just curious, how do the Trek supplied bearings differ from the Campagnolo 6805/6 bearings? I’m assuming they are bigger OD

[tombtfslpk]

I installed the Trek kit on my wife's Emonda (BB90)this Spring, it is not that bad to install. The OEM BB90 Sram/Shimano Trek bearings are the same outside diameter as Campy UltraTorque, but BB90 assembly is narrower than UltraTorque.
You can put the UltraTorque cranks and bearings in the BB90 frame but the bearings hang partially outside the bearing seats in the frame.
The kit consists of aluminum spacers that register and Loctite in the stock BB90 seal locations. The Loctite epoxies these spacers in location to widen the bottom bracket to Campy(ish) width.
I recall that there was a wavy washer and maybe some spacers to locate the cranks laterally in the bottom bracket.
You install the cranks with the stock Campy bearings, I understand that the kit from Trek is only for UltraTorque since the bearings are fitted to the cranks.
And YES you do need to install the kit with some kind of press(ure) to locate the sleeves while the Loctite sets.

Understand, my wife is scarcely five feet and 100 lbs, so she's no animal. But she has put a few thousand miles on the bike over the Summer without any issues.

Imagine how easy installing a B.B. would be if they just did something simple like ...... I don’t know .... maybe thread the B.B. shells??

Heresy!! it's much better to make something proprietary, then not support it in the future..Lower headset bearing trashed? Buy a new frame!!

One word: Overtorque.

Yup, agree...lots of other words out there BUT how many adapters made by shimano for the ton of BB standards out there? Plenty of ‘blame’ to go around.

I made this conversion when I purchased the frame some 12K+ miles ago. I had to modify the loctited cups by sanding down the outside face of the nd side to alleviate the rub from the crankarm. It really was a piece of cake. My only complaint is the lack of "weatherproofing" of the bearings which seem to require much more maintenance then my bikes that use the standard campy cups.

Oh, I don’t know.

My suggestion is sort of sticking it to the man! .......

Agree on the blame part but Campy deserves a special place in he!! for Overtorque by requiring a very expensive tool for installation and then discontinuing said tool.

I've got one and I'll rent it out for $1M/hr because if you've got an Overtorque crankset and you need to install it you're pretty well f'd without it.
