CX to road bike fit question...(4 posts)

CX to road bike fit question...Chicago_Steve
Oct 8, 2003 7:53 AM
I've got a 55cm Kelly CX bike that I've got almost 3 years of riding on. After a lot of trial and error I've got the bike is setup to fit me really well. I can do centurys, offroad riding, and commuting with a full messenger bag all day long with no lower back pain, numbness or other common fit ailments.

Lately, I've been lusting after Kelly's road bikes and notice that they offer the same seat tube/top tube dimensions (55cm x 55cm) in their road frames. Since the Top Tube length is the same as on their CX bike would I fit on their 55cm road bike?

Thanks, Steve

PS - Part of my current setup includes a slight positive rise stem and approximately 2cm of spacers. This puts my bars about 1" below my saddle height. A bigger road bike frame (say a 57x57cm) would eliminate some of the spacers and look less "fredlike" but possibly at the cost of a longer TT which will stretch me out...

My road bikes have a little more aggressive drop to the bars than my cross bike, but they're all about the same size.

Try the same size TT, and don't run 1cm of spacers. (cut the steerer long, so if you don't like it, you can make it the same as your cross bike!)

check out the differences in standover height for those two bikes. 6.8 cm difference. I feel you "might" be able to go with a 57x57 road bike. Of course, it might be ideal if you could compare the two built up right next to each other with a tape measure.

What length stem do you have on the cross bike? You can easily go 120 on the road bike with no problem.

Actually I'm running a 120mm stem on my CX bike right now... I think I'm going to save some pennies and have a fitting done... Probably money well spent...
