    Mounting aero bars on OS 31.8 road bars

    Maybe someone can offer a suggestion. I'm trying to mount a set of Profile Carbon Stryke aero bars on my Felt road bike. The Felt handle bar is OS 31.8 mm, and the aero bars are 31.8 with a shim to fit 26.0. Problem is, there's not enough room beside the stem to clamp the aero bars onto the 31.8 diameter, but the rest of the Felt handle bar diameter is smaller than 26.0 (approx. 25.4). I hate to cobble up some type of shim to adapt the 26.0 set up to clamp onto a 25.4 base bar, but haven't found another solution thus far. Suggestions (other than “toss the aero bars” or “change to a 26.0 base bar”)?

    About the only options I'd take are along the lines of the ones you outlawed. If the clamp area around your stem is too small, about all I would feel safe doing, is getting a drop bar with a larger clamp area. IRD makes a allor wing bar that I use that has a large enough area-for ~$50.


    I suppose you might be able to contrive a shim yourself--but aerobars make a bike squirrley to start with, and ANYthing other than a rockhard confident interface between clamp-on bars and dropbars will result in a faceplant.

    IMHO.
    Man. You are all stuped.

    I've heard of many people using a strip of aluminum from a soda can as a shim for 25.4-26.0mm conversions. Do a search on the forums for handlebar shims and you should find some good info. I don't know how well it works, but some people seem to find it works well.

    You want those bars fastened securely - think hitting bumps in the aero position!

    New base bar?

    Oval Concepts makes stems and stemcaps that will mount their extensions and armrests without changing your base bar.
