    really light Ritchey Logic Prestige Super Tubing for single speed

    I have a '96 Mongoose IBOC Pro-SX frame that is built with Ritchey Logic Prestige Super Tubing that weighs, if I recall correctly, about 3.75 pounds. I built it up in '97 with a '97 Judy SL fork, XTR components, Syncros Pro titanium seat post, Race Face Turbine LP cranks, Mavic 217 rims, and White Industries hubs and it was a 23 pound bike back then. It has since been torn down and I ride a '06 Turner Flux now.

    I'd really like to build the frame up again, but as a single speed. How much more abuse does a frame receive when built up as a single speed? I know I would lose some pedal efficiency because of the fact that this frame flexes. Will the side to side rocking destroy it, or is that what these old steel frames are designed to do?

    Thanks.

    I have 0 experience with that tube set but I'd say do it. Sure you'll have some flex, especially if you're big and or a masher but not so much that you'll be throwing chains. Set it up with great chain line and I see no problems. A ridged fork is a must though, and wide risers, and fatties. JMHO of course. It should make for a great SS. Quality, vintage steel bikes are a blast to build and well suited for this purpose. Although built more stout, my 90 Ala Carte was SS'd for over 6 years with nary a whimper. That bike stole many a heart over the years and turned quite a few onto single speed riding. As far as breakage goes? Who knows. Steel's easy to fix if you do. Consider it a battle scar.
    Zip ties? Not on my bike!

    Want:
    650B rims or wheel set. 80's vintage 32 or 36 x 135mm

    Yep, it should be fine. SS doesn't put any more stress on the frame than a strong rider that likes to mash the pedals. The handlebars likely take more abuse though.
    Each bicycle owned exponentially increases the probability that none is working correctly.

    I plan on changing out the stem and handlebars. The 135mm stem length was fine 15+ years ago on these XC geometry bikes, but they didn't do to well on technical downhill sections. Those Answer Hyperlites will be traded out for a riser bar of some sort.

    I'm about 5 pounds too heavy right now, at about 160, but I should be able to start shedding that starting in the next couple weeks.

    I have one of those frames that needs stripped and repainted then I may set it up as an SS. It was a great climber as I remember. Post some pictures and a ride report when you have yours together.

    I'm not sure what to do with the forks though. It's an old frame design, probably built for no more than an 80mm fork. I believe my Judy SL was 63mm. How are the rigid Dimension forks?
