    What stem length you running on your Trek?

    Just curious what everyone is running. I feel like the 105 stock Cobia stem is a bit long. Was wanting to try a new stem and wondering what everyone else is running?

    I had a 90mm on my EX8 and went to 70mm. I like the improvement in body position and quicker reaction to steering input.

    I replaced my OEM 105mm stem with a 70mm on my 2010 Rumble 1. Also swapped out the OEM bar with a Chromag Fubar OSX 780mm. Same comment that SpeedStarr said but also way easier to bring the front up over objects or just for fun.

    Thanks for the input everyone. May try 70. It seems to be what people are happy with.

    Stem length is totally dependent on rider size, frame size and riding style.

    I run a 100 on my Superfly XL. I'm 6'3" and normally proportioned. 700mm low rise bar.

    Also length changes with height, check out this calculator to see how your stem change could effect your position. Stem Comparison Tool | yojimg.net

    70mm here with 685mm bars on my 2012 Superfly; much nicer for me than the 105mm stem and ~740mm bars it came with.

    620mm origin 8 all mountain pro riser bars and bontrager race 65mm stem on my ex9

    660 mm raceface next SL carbons and 50mm Dirty dog reaper stem on my trek marlin 29er single speed.
    I think they both came with 90mm or 100mm but I have short lil T-Rex arms and had to swap em out.

    Something just hit me. My Fuel 7 has a 9 cm stem now with 7 degree angle. Should I change to a 5 cm instead, the bar would also come DOWN abit, not just closer. Maybe I should compensate that by getting a 17 degree 5 cm stem instead of a 7 degree. So that basically the handlebars will only come closer to me, and not further down in the process.

    How did you guys do when you switched to shorter stems? Did you go with a higher angle aswell?

    90mm stem down from 105mm on a L frame Mamba. Perfect for me helped some on descending with a 700mm bar.

    I run the stem inverted.

    I've wanted to get a new stem as well but wasn't quite sure on the length I needed. I'll use the calculator. I have my OEM stem inverted right now on my Marlin.

    On my 2012 EX8 I have switched to a 50 mm stem and a 750 low rise bar. It's been comfortable and has increased my handling on my rides. However, everyone is different, but I like this set up for me. I have the same set up on my Slash 9.
