Campy Ultra Torque Crank Fixing Bolt question

Was told by the shop that the bolt needs checking every so often as they can loosen up. After the first 30 or so miles mine was loose so re-tightened with torque wrench and the Campy UT-BB110 tool.

Question, is this really a common issue that must be re addressed weekly (100-200 miles) or just after the initial installation?

If it occurs on a regular basis, why not apply Locktite Blue?

I've got well over 5000 miles on my ultra torque and have had no problems with the crank fixing bolt loosening. I have taken it apart three times and put it back together with no problems and no loosening (and no loctite). Just a wacky thought - maybe the wavy washer was left out? There is a specific Campy warning (in the ultra torque instructions) that leaving it out will result in the bolt loosening. No way it should need tightening every 100-200 miles.

I have 900 miles on my Record UT installation. Have checked torque a few times over the season, and no isues at all.

The proper torque on that bolt is really pretty high...if they used just a normal 10mm wrench they aren't getting it near tight enough which is why it is loosening. Tell them to put a torque wrench on it and get it to the Campagnolo torque spec. You get it there and it will nto come apart unless you take it apart.

OP said "re-tightened with torque wrench and the Campy UT-BB110 tool." So sounds like he got that right.

I did this myself after the initial install by the LBS. Although you know, very hard to find the manuals for Campy on the web. Not at their site. Pro Bike Kit has them under each part thankfully giving the torque values.

Yes they are. You can see all of them here http://www.campagnolo.com/jsp/en/doc/doccatid_4.jsp

Downloadable. You can also see the complete blowups of all the parts with annotated illustrations and part numbers and you can even see what the parts cost in Europe (kinda interesting).

I can tell you after riding the Campy I am switching out the DA on my Look this winter. Function and ergonomics work so much better for me than the DA.

Thanks to all for your help.
