yup. Just a couple mm smaller. May be an issue if you don't have a long-reach front brake laying around. If you need one, you can pick a used one up for like 5 bones.

Any way you could post a decent picture or two of the bike? or close up of the logo/headtube/lugs/crank? I've never seen one of these before and google was of no help. Would be nice for the archives/search function in case someone else finds one and is looking for info.
