1996 M900 Geometry?

I have an M900 with an aftermarket Rockshox fork and I'm looking for a new fork for it, but I want to do this correctly and find the right geometry.

I'm having a hard time finding the frame geometry of the bike, Does anyone have the geometry spec for these? I found the stuff for M700, but i don't know if they used the same frame.

If anyone has the info, or knows where to find it, that would be great.


Thanks.

As I recall, the CAAD3 frame used on the M series in 1996 were all the same geometry. Only differences were for the different size frames(increase/decrease in top/down and seat post tube lengths) Head tube angle and seat tube angle would remain almost identical. The bike should have been equipped with a rigid P-bone with 1 1/8 in. threadless.

Edit: the M800 Beast of the East models would be an possible exception since they still had the sloped top tube and higher bb height i think.

Cool, Do you have the geometry for those? I cant seem to find anything. If i can find a stock pbone fork id like to run it, but otherwise i'd like to find a close match in geometry.

Geometry is on page 51 of the 1996 catalog, download it here:

I would think that a fork with similar axle to crown length and travel would be fine if you are happy with the handling of the bike as it is now.

Oh thanks. I flipped through the catalog but I guess I missed it. And i am not happy with the handling of the bike, hence the need to do this properly.

I wasn't sure if Cannondale made those frames to take a suspension fork or not. The 1996 F200 and F400 had conventional suspension forks but they were CAAD2 frames. I don't have a P-Bone fork to measure. Check your head tube angle with the tires aired up and see how it compares to the 71 degrees that the catalog lists. If the angle is considerably less it's probably because the front end is too high with the present fork. You could also measure the bottom bracket height. It should be 1.4" below the wheel axle centerlines. Make sure the bike is standing vertical when you measure.
