    Trek 800 Frame help

    Hi everyone,

    I am trying to build a single speed road bike from a stripped down Trek 800 Sport Frame.

    1. Can I use wheels which are larger than 26" with the small frame?
    2. Does anyone have any suggestions for a new lightweight crank and handlebar stem that will be compatible with this frame?

    Chain 1/2 x 3/32"
    Handlebar Stem Hi tensile steel, rise
    Headset 1 1/8" sealed mechanism

    Crankset Sun Race FC-M35, 28/38/48 teeth

    Hubs Aluminum, Q/R
    Rims Matrix 550
    Tires 26 x 1.95" Bontrager Connection
    Spoke Brand Stainless steel, 14ga. (2.0mm) straight gauge

    no on the wheels. brakes won't lineup with rims.
    if you're worried about weight, why a low end mtb frame?

    You can possibly use 700c wheels if you do not use the canti posts and instead use caliper brakes. I have put 700c/27 inch wheels in 26" mountain bike frames and used caliper brakes instead of canti/v-brakes.

    You can easily enough make it a single speed (not fixed gear) with a chain tensioner but no to making it a fixie if you want to do this cheaply. It has vertical dropouts which do not work well at all with fixed gear bikes.
