something I'd suggest is getting thinish (1.25-1.5") smooth tires/tubes and putting those on, and outfitting your mtb with bar ends. I only say this because if you're running on rough roads, or commuting, I'd think you'd be able to appreciate the extra tire width and shock to the bike... things you wouldn't have with a rigid roadie.

I would love to make the speed-demon leap to roadies, but I live down two rough gravel roads, and even my 1.5" tires tend to be squirrelly and weird on them... Not the place for a slick, light, graceful and delicate road-gazelle.

For now, my rough'nready little mtb will have to do, but honestly, I was completely comfortable aside from hand fatigue (those bar ends got a little hard on the hands after awhile... probably wouldn't have been so bad with better gloves) and butt fatigue (got a brooks saddle for that) after a 40 mile ride this summer.... and that was WITH fat, nubby tires.

Never underestimate the ability of proper components to improve your ride.

okay, too many typing errors, time to go home and to sleep!

Sweet bikey dreams!
