    Cracked frame...new bike.

    Last Saturday I was putting some easy time in on the trainer, when I glanced down and noticed a huge crack where the top tube met the seat tube. And it was flexing with every turn of the pedals.



    I had gone for a ride outside the previous Wednesday, then indoors on Thursday...my best guess is that it cracked while on the ride, and it propagated while on the trainer. Anyway, I'm stripping it down to take the frame to Specialized to see about a warranty replacement, although I don't particularly want the same frame. It was a 2008 Specialized Sirrus.

    After a lot of searching, I found this Opus cyclocross bike, and I'm very happy with it. 2012 frame, and the seller had upgraded the drivetrain to Rival shifters and Apex derailleurs. Also with Easton EA70 rims.



    Just got back from a quick 40k ride on it, and I'm annoyed that my phone crashed during the ride, because it certainly felt faster than the old bike. Still need to fine tune the fit, the seat has to come ahead a bit and I may flip the stem.

    Well, that sucks about your sirrus. Hopefully Specialized will hook you right up but unless they're out of warranty frames, you're probably getting the same thing again. How far into the seat tube did your seat post go? Presumably well well below the break.

    Looks like it failed at the weld, if warranty is of no help, I wonder if it could be re-welded?

    naw, not interested in putting even a dollar into the frame.

    I thought maybe I had the seatpost extended out too far, but when I pulled it out today it was at least a couple inches to the good beyond the "min" line.

    post inserted, extend beyond the bottom of the lower end of the top tube miter weld..

    post at marked minimum on it may still be too far out if its not in the frame far enough.


    steel bends before it cracks, that is aluminum. its a fatigue crack
    check with the dealer you bought it from, might be under warrantee.
