53 cm. Rack's a Tubus Logo. There is a NAT sticker and a reflective Chicago flag sticker on the back fender. Front wheel locked with Pinhead. Rear wheel had standard QR. Rims are Mavic, tires are Maxxis Re-fuse. Derailleur is Ultegra, STI shifters 105, rear hub Tiagra, Avid cantilever brakes (that are squeaking today 'cause it's wet). I made a post on Stolen Bike Registry and will provide more details (like serial number) when I get home. I was always kinda mad about that bike's crummy paint job but it doesn't change the fact that I'm heartbroken now. The bike will be 2 years old in February. I got it on Valentine's Day.
