    I'm looking for a more comfortable, less "fidgity" tire than what is now on my bike. (700c x 23mm). Would 28mm fit? Or should I play it safe and go with 25s? Rims are Mavic MA40s. I ride mostly paved bike trails with this bike.
    What exactly is "fidgity" ? On MA-40 (and others), 25 or 28mm are no problem. Currently, I even ride a (nominally) 32mm comfy rear one from Panaracer. However, fat aluminum chainstays, and sometimes geo, can be a problem: There are "modern" bikes where 28mm wont fit.

    To make it short: Unless for serious road racing in some instances, I'd always prefer 25mm (and >=28 on light sand / gravel).
    I've fondled a 979 but never squeezed any tires in there. How much space do you have with the 23's between the chainstays. Those are generally the limiting factor in tire size.

    Yep, the chainstays - that's why I'm asking. The space is tight and I wondered if anyone had experience with this (28s back there). By "fidgity," I think slightly "skittish" or simply overly-sensitive might be a better way to describe it. This is, no doubt, largely due to the fact that the bike I've been riding the most is a mid-80s Schwinn High Sierra with 26 x 1.75s on Araya rims.
    Check out Bruce Gordon. He might have something for 'ya. ;-)

    Thanks, everyone! I put on some 28mm Panaracers and they fit fine and work very well. However, I doubt anything any bigger would fit. It's very tight back there. As soon as I have her really spiffed, I'll post some pics.
