    Yeah I'd anticipate 60mm to be the most popular.

    I will have that and a number of other things to sell as I have just too many parts around I don't use anymore.

    I'd buy an 80mm for the right price since I'm curious if I'd like it more than the 70mm thats on my Banshee currently.

    70-100 will be easiest to offload.

    I run fidy's on all my bikes...FYI I've never paid more than $75 for Thomson X4 anything. I run their stems and seat posts on all my bikes.

    50 or 60 are standard now. Longer than that is very old fashioned like 50mm travel forks.
    I got some bad ideas in my head.

    THIS! But don't tell that to the XC crowd who continue to think that bike "fitment" is the first and foremost deciding factor for stem length (heaven forbid - I got several negative rep posts for suggesting the TRUTH!), LOL!

    Have FUN!

    PS - I'd take an SM-E130!

    I don't get it. So everyone needs to disregard fit and slap on a 50 mm stem?

    Stems should be used for handling effects not fit on mountain bikes. Over the years mine got shorter until now I use 50-55mm for everything including mellow xc rides. Elbows bend for a reason.

    Some people are just absurd and don't think before they talk/type. Yes, 50mm and 60mm have become very popular. Yet, there are still those who are aware of the benefits of 50mm and 60mm but still prefer to go longer do to fitment advantages. I personally switch between a 50mm easton haven and 50mm renthal duo stem and I am currently waiting on a 70mm thomson X4 I got for "Free" for ordering a dropper post from jenson

    Right. And the "handling effects" of a shorter stem might not be the effects everyone wants or needs.

    Me either. 50mm stem with narrow bars sounds horrible but seems like most people dont care about any other element of bike fit except the stem length. Nor any elements of frame geometry except head angle and chainstay length.

    it all depends on the bike's geo.

    i think with slacker angles and more aggressive riding/riders/terrain shorter stems make more sense for handling when used with today's wider bars. It makes sense to get your bike fit with frame size and use stem size to address handling. if you're gonna use the stem to "fit" then fit it while your standing off the saddle cuz that's when it's in play the most. when you hit tech or at speed.

    ...so to the op...50mm @ 0deg, please and thnx.

    Couldn't have said it better myself 53119! I think too many readers sit while riding or have dated bikes ;-)

    One point I'd like to make is that there will always be those individuals who could ride either small/medium, medium/large, large/xl, and decide on the smaller frame for maneuverability but need to stretch the cockpit a little bit. I am 5'11 on an 18" new generation slayer and I have very long arms. Currently I have 770 bars with a 50mm stem and I can tell that a slight bump up to 70mm will do me well in terms of weight distribution.

    Excellent point. In general, I could have the fit I want with a medium and a 75mm stem, or a large with a 50mm stem. If I pick the large, I lose some standover clearance, I get a heavier frame, I get a longer wheelbase, and I get a higher head tube which could effect getting the optimium bar height. A lot of disadvantages by going with a large just to run a shorter stem.
    So, is a 75 mm stem too long? Hell no. This stem length think is WAY overemphasized. The disadvantages of a large frame (for me) are much worse than having a longer stem, which I don't find to be a disadvantage at all. It just changes the weight distribution a little bit.

    "You must spread some Reputation around before giving it to smilinsteve again." Good points all around.

    Dont get sucked into one detail when your cockpit and steering geometry is affected by much more than stem length.
