Carbon crank question

this is a bonding failure - i strongly suggest you return for warranty. do not try adhesive. do
/not/ ride until replaced.

Hello group,

I have a set of Campy carbon cranks. There appears to be a small separation at the seam of the
non-drive side crank where it joins to the bottom bracket. The separation opens about 1 mm when
weight is applied to the crank. Any reccomendations as to what kind of adhesive would seal the
separation without damaging the carbon fiber? Or should these just go in the garbage since this is
such a high stress point on the cranks?

Thanks, Steve

If you are the original owner I would get a warranty evaluation on that promptly.

And I would not ride them. Crank "repairs" make no sense at all if you stand through yellow lights!

warranty those things. The left side had some problems anyway-They have to be less than 3 years old.

Wow!.. for 800 bucks I would demand a replacement.

My LBS has a set on display. If it were a tripple it would be on my bike right now.

They have a set on a new Moots Vamoots/SL along with the new Record carbon Fiber derailiers.

HAND Lusting for bicycles and parts is good!
