Hadn't checked honestly. I'm just sussing out opinions before I do it. I would think there's room for a 2T change up front. That would necessitate a new chain maybe.
Just used a gear inch calculator instead of relying on my scribbling....Going from 49t in the rear to a 42t would yield 16.7% increase whereas running a 15/49 yields a 15.4% difference and probably needing 4 more chain links.
