I've recently finished building this old Sunn Cycloss frameset up. It arrived in a very anonymous and rather neglected state (incorrect sized seatpost, seized stem, etc). I believe it is from 1998.
The geometry is pretty special, with big clearance far beyond a 33mm CX tyre, so hopefully going to be great for the longer off road rides I enjoy that invariably involve lengthy hike-a-bike sections.
I've looked online a lot, but can't find much info on it, so hoping someone on here might know a little more about the design
Despite the presence of mudguard eyes on the dropouts (standard sunn stamped mtb from what I can tell) there are no bottle bosses. That would make sense for a traditional cross bike, but this is anything but that!
Meanwhile the fork looks original, but has double eyelets on the dropouts. Other pics ive found online show forks with either single or no eyelets. Perhaps it has been replaced, or 1" chrome forks were generic enough there was little consistency in what they used?
The final bit of fun was the front mech, which is top pull. I figured I would just put a mtb triple on, but the cages were so deep they rubbed off the chainstay. Luckily I sourced an old Shimano CX top pull that works well. However, the frame predates that component by at least 14 years, so what did they use originally?
However, no grumbles! I've always wanted a Sunn off-road bike, but have given up on 26" wheels. This does the job perfectly. Right now it has 38mm tyres but I'm pretty confident that 45mm will fit alright which opens up great riding options.
The new retro decals from France add a super splash of colour, now I just need to clear the flu and go get it muddy!
