That's funny, I bought my kurt kinetic yesterday. Big Problem!!! My Giant OCR3 doesn't fit... My bike frame is over one of the devices on the back of the wheel that hooks up to the trainer. We don't know how we're going to fix this to make the bike fit on the trainer. If you buy one, bring your bike to make sure it fits. The store put a Specialized bike on the trainer when it came in so I could try it. Then I brought it home...OOPS! But it's rated THE BEST!
