    Chainring size?

    So I recently built a SS Mountain bike and I am looking to run a primary chainring for city riding. What size chainring would you recommend for me.

    The bike will not be doing a whole lot of hill climbing more of urban cruising.

    Here are my current stats on the bike:

    Frame: Swobo Folsom Frame
    Bars: Swobo Folsom Handelbar
    Headset: Chris King NoThread Set-11/8
    Stem: Elite 5d 110mm Thomson
    Front Hub: Chris King Front Disc Hub-32-h
    Read Hub: Chris King Rear ISO SSP Hub-32h w/ 18t Cog
    Skewers: CrankBrothers Split
    Crank: Surly Mr. Whirly w/ 94x33t
    Pedals: CrankBrothers XX 50/50 Sealed Bearings w/ Orange Inserts
    Breaks: Avid 09 BB7 Disc Break Mnt Front/Reare 160mm Rotor
    Rims: Sun CR-18 26" 32h PV Rim 559 ISO
    Spokes: DT Champoin 2.0 914ga 262mm
    Seatpost: Ritchey Pro

    Thanks for your help.

    Yo. I've got the same bike. I just swapped the 32 ring for a 42. So now I'm 42x16...freewheel. Perfect for the streets of Los Angeles.

    I recently purchased a single speed that came with a 42t chainring, but its a commuter/road bike frame with 700x28c tires. A 42 would work, but you may need a 17 or 18t freewheel on the rear to make up for any extra weight, or rolling resistance from fatter tires. My bike has a 16t freewheel, but I'm considering swapping it with an 18t to enable me to climb hills easier. I've only had to get off and walk it up one steep hill so far, but I haven't rode up long hills yet either.
