Recreational Cyclocross and Gravelbiking This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like :The Dirty Kanza". We also have a dedicated Racing forum for the Cyclocross Hard Core Racers.

Is this impossible or stupid...

Okay, i really want to tinker with something so i had an idea to change my
CANNONDALE 3.0 ALUMINUM COMPETITION SERIES, into a cyclocross-esque bike.

Kind of like a total makeover deal. So how stupid/impossible is this idea? Can it be done with out altering the frame??

don't scream at me if it is a bad idea. i am just really bored and want something to work on in the summer while i sit in the AZ heat and when i am not on my trainer...

No, it's not impossible, you don't need to alter the frame, and such conversions can work very well indeed - you get drop bar aerodynamics and MTB tyre choice and offroad traction.

Do a forum search for advice; this has been discussed here before. The key problem is getting drop bar shifters that are compatible with MTB derailers (btw, it would have been nice if you'd told people that your bike is an MTB rather than leaving them to google.) There are at least three solutions - a shimergo conversion, bar end shifters, and the minoura space bar hack using MTB gear shifters, if there are any break leverless ones compatible with your derailers. Shimergo is probably coolest, bar end shifters is the easiest.

The deraileurs shouldn't be a problem. Only recently with dynasys have shimano mountain deraileurs and road brifters become incompatible (you do, however, need to pair cassettes and shifters). however, if you're thinking of running 700c wheels in there, you'll either need some cantis with a huge amount of pad adjustment room (paul's spring to mind) or a plate like Mavic used to make to get the canti studs up higher.

Also rear spacing can get weird, but 7 speed mountain was 130mm which is what 8/9/10 speed road is these days. You might want to google around to confirm.

thanks guys,

yeah sorry it is a MTB. I have a 9sp XTR deraullier on it. (but not matching shifters), i was thinking maybe putting Moustache bars on it. I am sure you'd have to see my rims, but would i need to get new rims or there are options for more "road esque" tires i can slap on them?

A 9 speed mtb rear deraileur will work with a 10 speed brifter. For the front, I used a mtb deraileur with a triple brifter and a mtb crank, used only the middle and outer ring and limited the cable pull. Worked perfectly. If you want to keep the wheels schwalbe makes a 26 inch version of the cx pro, 1.35 width.
