I have a 1991 Cannondale ST600 and I love the bike however the fork has been causing some trouble for me. The dia-compe 986 brakes are at the limit of their adjustment to fit the original wheels. Now using a set of wheels wider than the originals it is almost impossible to adjust them correctly. The posts are too high.

I've noticed in the catalog the ST600 uses a different fork than what I have on the bike. It looks like Cannondale reached into their parts bins to equip these bikes and it really seems that the fork was intended for 27" wheels instead of 700c.

The axle to crown also seems off. I've measured ~412mm a-t-c. I haven't put a level on the top tube yet, but it sure seems to slope upwards because of this tall fork. Looking at images of other 91 ST600s with the unicrown fork and they seem to have this slope as well. The fork in the catalog looks significantly shorter, but by how much I don't know. I've been on the hunt for a replacement fork and am even considering having something custom made for the frame. I'm wondering if anyone on here has an ST600 with the correct, per the catalog, fork who can measure the distance of the axle to crown length? 1991 ST1000 should be the same geometry as well, so if you have one of these the measurement would be useful to me as well!
