    handlebar shim safe?

    I just bought a 02' Santa Cruz Bullit and the stem is much too long. I wanna buy a 40mm stem but my handlebars are 25.4 and all the new short stems are 31.8. Instead of buying a stem and bars to fit, is it safe to use an eBay shim to increase the bar diameter to 31.8? I am definitely not going to be riding hard as I'm completely new to the sport but I also don't want the bars to move on me

    Does this help?

    50mm is the shortest and while you may be able to find something for less than 50 bucks, this is a really nice stem.

    Yes, the shims are perfectly safe but as said, I would just buy new bars.

    Personally, I don't see the point of oversized bars. They are more rigid, so more harsh, and have a less area for mounting controls and lights etc on.

    ^ While we're off topic here (hey, it's mtbr) there is at least some marketing that's says the exact opposite. Theory being that the flex it'self is responsible for the "harsh" feeling or more fatiguing. When the bar flexes it immediately springs back to it's static position and to that I can see the logic. Having ridin all the sizes over the years not sure I can detect any difference in comfort but the 35mm feels MUCH more precise.
    It is no measure of health to be well adjusted to a profoundly sick society.

    Sounds like nonsense to me.

    well, I skipped the shim and just went for a new truvativ hussefelt 40mm stem and truvative hussefelt 700 riser bar. the bar that came with the bike was really narrow anyways. hope I like the combo
