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.
