Is my frame cracked/cracking??

Did you find out whether it was a paint or frame crack.

 

I have a Jamis with exactly the same problem, crack looks exactly the same and carbon seat stay bonded to aluminium tube.

 

I took it to the LBS and they sent it off to be load tested.  He said they load it with a force and measure the delfections, if its cracked it should be larger than normal.  He said the deflections were fine and that it was just a paint crack.  Not sure whether to trust him as i was looking to buy the bike off a friends of bloke at the shop.

My Scott Genius LTD had cracks that look exactly like that.  sent pics to the (new) distributor, immediate frame replacement.

In East London there will be a lot of machine shops that deal with the motor trade, which has ver high specs. You could contact any of the bigger ones and they will be able to put you onto a company that can dye pen, x-ray or do ultra sonic testing. Will cost a bit, but cuts the possibility that the LBS might bulldust you out.

JD just speak to Omnico before you spend to much on testing. They are a really top notch company.

I wouldn't worry too much about all these tests. The frames looks like a 2007/2008 model and should still be covered by the warranty.

Whether it's paint or the aluminium that has cracked, neither should have happened. Unless, of course, you've done something you shouldn't have, like riding it off road.

Push for a replacement.
