Undoubtedly it could be done, but it would not be easy. Large diameter rollers (4.5") would helpful.[/QUOTE]
I keep my Swift at the office for use when I travel. I just took my rollers there for lack of space at home. Lo and behold the Swift fits just the same as my roadie, at least wheelbase-wise. No adjustment of the rollers was necessary. Indeed it is a bit wild. Greater effort and concentration is needed, but most of what you say is academic. Yes it's more difficult but all the more reason to try, eh?.
All the riders at the office are getting a big laugh out of riding the Swift on rollers. Some of us might even get good at it.
