I have a '05 OCR2 and a '06 TCR c3. I love the TCR! I haven't had a problem with the fit and climbing on the compact double has actually made me better.

I did something very stupid on my first ride, I took it out for 62 miles and cramped like crazy. I had a couple of tweaks I had to make but afterwards I was fine.

You'll enjoy both!

Just ride!
