    So I'm building my GF an EMD 9...

    Got a question...regarding stem length.

    I'm doing a frame up build and wondering about the stem length.

    Its a small and she is 5'6". The stock Niner build comes with a 80mm stem, but everything I've been reading about says to go short.

    On my own Specialized Carve (medium) I'm running a 70mm (unsure about that length too). Stock it came with a 75mm.

    On her bike, I was thinking about going with a 60mm and some 685mm bars.

    She currently has a Pivot Mach 5 and does not like how it rides. That thing came with a 90mm stem. I put a 75mm on there, but she still does not like the ride. After she rode my Carve is when she decided that she wanted a HT 29er.

    I've been a dedicated roadie for the past 5 years...so the MTB thing is a whole new language to me.

    Any suggestions?

    Thanks!

    Hard call with seeing her on the bike, her height is just the tip of the iceberg on stats needed. I have always found that's it's best to run up to Performance Bike and get 3 cheap ones to check the fit and then when you find what's best, take them back and get a good one.

    I don't know if this is a very moral thing to do but their policy is "take anything back, no questions asked".

    70 of 80 may not be that far off depending on how much sweep the bars have, I like around 9 deg sweep

    Never considered the sweep.

    My EC70 XC Wide has a 9mm bend.

    Crap...now this reminds me that I need to look at my stem. It came with a 100mm and I told them it was going to be to long but they said we would just change it out when I picked up the bike. In my rush to just grab the bike and go ride, I didn't even think about the stem.

    That be said, the bike felt fine on my first several rides but yesterday, I went to a very technical trail and I felt I was over the bars too much, on sketchy downhills.

    Running to the shop is out of the question as it is 75 miles from my house with nasty traffic the entire way. I should take my own advice and go get a few from performance but knowing me, I will just order a 80 RDO and hope I like it.

    Are you guys running zero stack?

    This looks like the HS the EMD uses:
    Orbit 1.5 ZS

    I guess if your going more XC racing...then maybe the long and low stem is better...but if your more into "shredding" the stubby stem is the way to go.

    70mm stubby on my Spesh:


    Polar opposite to my road bike. 110mm/-17


    The stem angle looks alot more exaggerated in the pic. At a 73deg HTA, the -17 is level with the ground.

    I just built my wife a small EMD 9. She is 5'5" with pretty long arms. I did a 70mm x 0 deg stem, with Niner flat top bars cut to 690mm and she feels really comfortable. Just throwing it out there, hope it helps.

    It did!

    That is what I'll probably go with. I'm going to give her my 70mm Thomson and move to a 80mm. As for bars...I'll get her some 685 or 690mm.

    Now that is sorted.

    Gearing is the next thing I'm thinking about.

    XX1...She is your GF and deserves the best.

    Better yet, give her your old drivetrain and you get XX1.

    Haha...the XX1 did cross my mind since the XX1 will be tricking down to X0 for next year.

    e*thirteen has a nice set of TRS cranks that I've been eyeing. I just might pass my current pair of cranks (22/36) to her, and get an 11/36 cassette.

    Took advantage of Price Point's Shimano sale.

    Pick up XT brakes, RD, FD, and shifters.

    Got a Fox 32 F29 OE fork from Jensen. Pretty good price at 400.00.

    Parts should be here by mid week!

    I'm 5'6", but I have arms like someone who is 5'8". I use a 100mm stem on my small Air9 Carbon.

    Finally ditched the SRAM S1200 cranks.

    Put together a sorta "custom" 36/22 setup with Blackspire rings.
