I've owned 5 older Cannondale CX frames and a 2011 CAADX. I much prefer the geometry of the CAADX to the older frames. Versatile frame that can be used for fast road rides to light touring.
Best way to get wider tires will be to switch to 700C wheels. Let me know if that's an option and I'll see what will clear on your frame. I have a couple of mid 80s touring frames here. I'm running 32-35 mm tubulars on two of them, haven't tried anything wider. Note that switching to 700C is...
Did you measure from the edge of the cup, essentially from the bottom of the head tube if in a frame?
I'm running 38 mm Schwalbe Big Bens on another XS800 with about 10 mm clearance to the fork, which seems adequate.
Thanks for the photos. The XS800 will primarily be used on mixed surface road rides in good weather. While I'd prefer a slightly wider knobby tire, I could make do with a 30 mm commuter type tire. Lots to consider here as I would need to build a disc brake wheel and buy a rotor and caliper...
I would have to weigh them all again but I'm guessing that my 1995 M900 is my lightest MTB. Catalog says 22.4 lbs. but with tire changes, rack and accessories it's around 24 lbs.
Seems an odd place for the fork to fail. I would have expected it to be much closer to the crown of the fork. If the lower bearing was really sloppy it might have contributed to the failure.
I have an XS800 cyclocross (700C) fork that needs to be rebuilt, was rusted solid when I received the frameset. Could you measure from the edge of the headset cup to the axle centerline? I've read that 700C tires will fit on the 26" forks but don't remember the maximum size. Your fork will...
28" has never been commonly used as a designation in the USA but has been used in Europe to refer to 700C (622 mm ISO) tires. Not sure why as most traditional road tire diameters are closer to 27" than 28". There were also 28" rims used in Holland, UK, India, Sweden and China that were 635 mm...
I only have one Taiwan built Cannondale, a CAADX cyclocross from about 15 years ago. Purchased new as a frameset. It's been a great bike. Disappointing to hear that you've had problems. It's hard to comment without seeing some photos of the issue.
