Re:
44 ? :shock:
That's not just a modified MTB frame, that was built from the ground up to be a 28" bike.
It's in none of the catalogues, I have downloaded all the catalogues I could find in the last 4 years and checked them all just now.
It's not in the Sbike Speedbook either. There's only 1 model with 28" wheels in there and that's a classic double diamond frame.
What you have there could be a one-off. There's not a shred of info to indicate its existence, yet here it is.
This is the third time in 4 years that I come across a frame that defies both the catalogs and the rest of the model range. (the Ti Sbike, my full suspension frame, now this one)
The only explanation I can think of, is that these things were built just to test the idea and then never made it into production. However that's just my guess.
Does it have a frame number? First place to look with those frames is the bottom of the main tube, somewhere inside the BB triangle. If not, it'll be the usual place at the bottom of the BB shell.
As for what to do with it : seeing as it's 28", personally I'd get a nice 28" cantilever-equipped fork that suits the frame's lines and build it as a full-on road bike, drop bars and everything.
