Hi John
Thanks for your reply,my mechanic changed the standard Campag UT crankset with a Compact FSA from my previous nike that was running fine.I then went for a 25km spin that had hills flats and descents,after 9km perfect,on rounding the corner to start a climb I heard the usual crack/click noise, went up hills out of saddle no noise,back on the straight after the hills one more noise and on the flat home one more noise as before.However the Campag I had double the amunt of crack/click noises.The compact FSA seems to have imperoved the performance but its still there,I am going to ask my mechanic to change the wheels front and back.Pedals/cleats/shoes have been eliminated.There are no visual cracks on the frame.Could an internal frame crack cause this kind of noise? Thanks a mil for your help, I will keep you posted.

Hello Sean, I hope that this message finds you well and I am sorry that you are having this issue with your UT. One way to narrow it down to the crankset/bottom bracket is to have your mechanic install a FSA crankset (only if you do not have to buy it...) and you ride it and see if the usual noise is still there. If it is, then it's probably safe to say that it's something other than the UT. If the noise is gone, then the opposite is probably true... If your mechanic is still hesitant to remove the wave washer and install the shims, well then maybe you need to find another mechanic that is more open minded to finding a solution to your problem. I hope that this info helps. Please let me know if you have any other questions. Thanks for writing! -John

Hi

I am reading these posts as I have a noise problem thats coming from the BB area in my Colnago CLX2 bought in jan this year.It is fitted with a Campag UT crankset.
My problem started from day, the click/crack noise that I hear happens almost ever 5km and after a 20km spin it happens around every 10k.
It happens more uphill and only once when out of saddle.
Yesterday I was on a spint with 8 climbs ie out of saddle and it happened only once.

My LBS has removed the crankset and sees nothing wrong.He is reluctant to introduce the shims.He is going to replace the crankset with a FSA to see if this sovles the issue.
So now you have one more with a noisy Campy UT system, would you have any other suggestions.

Greeting from a not-so-sunny UK.

I tell you what, John - some people out there must run some seriously poorly maintained bikes (I know for sure they do!). Those who claim that there is not a problem with UT BB's are either very lucky or ignorant.

I run two Ridleys (both 68mm shells) and have no end of problems with clunking. It's not just me - it's everyone else I know that has these problems with UT and not just on Ridleys - I'm talking Scott, Fondriest, Lightspeed, Pinarello, Colnago.
I speak from experience here as I ride and race upwards of 15000 miles per annum in all weathers.

I've tried the two wavy washer approach and that has helped although there is still movement enough in there to score the surfaces of both washers after 500 miles or so of use. It's a seriously flawed design, no matter what the response to the contrary. If you hadn't carried out the research you have then we'd all be the worse for it. That's a fact. 100%.

I'll be ordering a couple of shim kits and experimenting. I'm fed up with the constant stripping, regreasing, rebuilding, etc. I even switched to Ceramic Speed bearings and cups to see if that would help but to no avail. Shims are absolutely what is needed. Even if you decide to retain the (compressed to 0.7 or 0.8mm) wavy washer element you would still need to ensure that it had no more than 1mm of space to occupy otherwise your assembly will be slopping all over the place.

In either case, whether you keep the washer or ditch it, you need to shim out that 'difference'.

Keep up the good work, mate.

Cheers

Steven

Hello Peter, Thank you for your comment. I'm sure that you have more experience than I do with this. What flavor is that kool-aid?

"There weren't enough failures showing up in the field yet for this relatively new part to cause market flashback".

It appears from the email that the author experienced this alleged issue in 2010. Ultra Torque was released in 2006. Its now 2012. How many ultra torque cranksets do you think have been sold in this time? A google search still shows just you and your pathetic little campaign. No "market flashback" yet.

Meanwhile... in the real world:

Read it and weep. You're fooling nobody. Idiot.
