    Best gearing for converted train lines, paved trails

    I've got an old MTB circa 1993 that I'm considering converting to a paved trail, vacation, commuter type...thing.

    I'm interested in going the 1 x 9 route.

    I currently ride a 27 speed mtb and a 32 x 20 SS 29er mtb.

    I've found with the 29er, I don't have the need for so many gears.

    Would a 38t chainring up front with 9 gears in the rear suffice for mostly flat, paved, or crushed limestone trails?

    Thanks for any opinions!

    You can use a gear calculator to compare your current gearing to just about any combo imaginable.

    That would probably be more than sufficient gearing. The only thing to keep in mind is whether your old rear hub is compatible with a newer 9-speed cassette (which it likely isn't) then there's your derailleur, etc.... Maybe consider a 1x7 or even a 2x7 set-up?

    I'm actually going to go with new wheels and hubs, as well as new rear derailleur so hopefully all will be good.

    When I get the bike in the shop, the first question I'm going to ask is, what can stay, what must go, what are my options...1X9, 1x7, 2x7 etc.

    Should be fun.

    I don't intend to spend a lot, won't be something to ooh and aah over, but should be fun nonetheless.

    Thanks again for the info.

    For commuting, I'm not a huge fan of gears. Saying that, my current commuter is a 1x4. Sora rear, dura ace friction shifter converted to flat bar shifter with Paul's component.

    One is all you need. Four more than suffices.

    I ride what sounds like a very similar commute on my 29er with skinny tires (37c's.. probably makes it a 28er).

    I use a 32/14T ratio. It's probably a bit overgeared so you might be better off with a 15T or if you're a bit weak in the knees and in no rush maybe try a 16T.

    Don't forget a new shifter, too. Sounds like you might be spending more than you're anticipating.

    Old MTB means 26 inch wheels trains and paved paths mean flat, I would go 48 teeth on the front.

    We have a 'rail trail' near me, and I have taken my cyclocross commuter on it a few times. Biggest grade is something like 2% it's not paved, but well maintained dirt/gravel... I have a road double crankset up front, but no front D...I'm always on the big ring (50 tooth), and a mtb 8 speed out back. I haven't wished for more or less with that set-up. I think you'll spin out your highest gear if you go less than 48 or so up front.
    You have no excuse for driving to work
    (unless you don't have studded tires)
    (no excuse for that either)
