Cracked Tarmac SL2 Frame

Alright.. I cracked the frame on my SL2 just below the headset. Is this going to be ok to ride on? I have a race next weekend and I want to ride my SL2 but i dont want to eat **** at the same time... It will take Specialized about a month to get me a new frame but I think im going to buy a litespeed or Lynskey to use as a training bike from now on.. What do you guys think?

Put a band clamp around it and pray. Face plants suck, they suck worse when you take out the rest of the pack.

It would make a nice bit of wall art but that's about it's only purpose in life now.

It's not just the obvious crack in the front. Look at the lip that extends around to the left in that picture (right side of the actual head tube on the bike). It's all cracked and leaning out with none of those bits supplying any support at all any more. That frame is definetly toast and there's precious little holding the headset cup in place. A clamping band is not going to lock that together well enough that I'd trust it to ride on. The pieces that are cracked away will just crumble and provide little of the sort of support it requires to hold it all together. And this assumes that you can even get a clamping band to wrap around the rear size of the head tube cleanly without running up against the flare in the frame.

How did that happen anyway?

I was riding in a pace line and couldnt avoid a pot hole. I heard a crack sound but didnt think much of it (just thought it was a rock). When I was wiping it down after the ride i noticed the crack where the carbon mends togeather.. im so pissed.

The ****ty thing is that I bought the bike in Hawaii and im in Austria now. Do you know if I could take it into the local Specialized dealer to send it in to specialized?

It must have been one helluva pothole ! ! ! I'd be upset as well. You obviously finished the race without incident which frankly amazes me. I'm guessing that there's a tube that is inset in the matrix to accept the headset cups and that is spreading out the actual pressures.

If that is the case I could see where the frame could be repaired but I'd only go with that option if Specialized balks at replacing it.

To do a repair AND assuming that there's a tube that is inset in the head of the frame I'd look at wrapping the whole top area just up to the headset race with multiple turns of carbon tow fiber saturated in a good grade of laminating epoxy. Ideally the same epoxy used in the making of the frame. Carbon tow is a unidirectional bundle of loose fiber strands as opposed to a woven cord. What it would form would be a composite band similar in funtion to the idea of the mechanical band mentioned above but without the risk of point loading the carbon matrix. It would be a permanent part of the frame that would support and fill the cracked area. If you go with such an option it would be a case of using it on short light rides at first with frequent inspections to check for damage or head tube delaminating (any apparent looseness in the "headset" would be a sign of this potential issue) at first. Then as you learn that you can trust the frame the rides could become longer and longer but with the same frequent inspections. It would definelty be a case of slowly coming to a level of trust with it. AND NO MORE GIANT POTHOLES ! ! !

Specialized US is known for their good customer service, not sure what things are like on your side of the world.

I cracked it yesterday in a group ride and did a 60 mile training ride today.. I didnt notice any difficulty turning or a loose headset, but im skeptical about racing it next weekend.

I'd be watching for the cracks becoming longer with a very close and frequent eye. With the cracking comes the likelyhood of flexing. And with flexing comes the risk of the bond to the set in tube failing. If that happens it'll put that much more stress on the cracked areas that are able to flex. All in all it sets up the stage for a things to slowly get worse at first and then accelerate the damage and you end up on your noggin wondering what happened.

Considering the recent posts at Velonews about CF forks cracking at the bottom of
the steering column, it would be prudent to check out the fork as well as the forces applied to the head tube would be transmitted through the steering column.

Find a specialized dealer and have it sent back. That shouldnt have happened. How is the front wheel? did it sustain any damage?

Don't ride it. Specialized will require you to send the frame to them for inspection before they issue a warranty replacement anyway.

The wheel was a Mavic Ksyrium SL and they are prertty bombproof so they didn't take any damage. I'm going to go to the bike shop today.. I guess that this justifys me buying a new bike for now because I have a race on Sunday that im not going to miss and then the Eddy Merckx Classic in September that I need to train for.
