Title: crack in 057!
Post by: iman316 on September 13, 2017, 11:46:29 PM
i was checking my bike and I noticed the crack. I haven't done much abuse to this frame and its on the top tube right by the headset.

what should i do?

the pics aren't good but the crack is about 3 inch long and one side is higher then the other

Is it at the bottom of the top tube, right in the middle, a straight line  ?
Can you make a better picture? I cannot see if it's a crack or just the place where the mold came together.
How long do you have your frame ?

You have to contact your seller and claim your warranty. But have good quality pictures!
Ask him for options: send back your frame and get a replacement (you have to pay shipment to China) or make a deal with the seller and let if fix a local carbon repairer.

oh wow, interesting. I think this is the first 057 issue I've seen so far.  But yeah, it's difficult to see exactly what's going on in these pics. Please keep us updated!

Did you contact the seller?
This looks to be an under warranty issue.

In the meantime the seller sorts this out, you can strap the top tube around the crack with a carbon repair kit such as this one:

I've done that on one chainstay without any problem.
