    SS Stem Length

    I'm in the process of building up a Lynskey Ridgeline 29r SS and trying to dial in the cockpit. My FS26r is setup more XC with a 120mm stem where the grips are slightly below the seat height. I'm tempted to setup up the SS the same way which would require a 110mm stem since the top tube is a bit longer. Should I be thinking shorter, more upright riding position for a SS ?

    Personal choice but I like my bars where they're comfortable for multi-mile standing. For me that's right about saddle height. YMMV.

    What ever works for you man. I simply set mine up the same as my xc. Running a 110mm stem simply because my tt is a tad longer as well. I have a 5 degree stem flipped upside down so the stem is almost parallel to the ground and I still ride a straight bar.

    I set mine up based on bike fit at a shop. I was able to use a 35 degree inverted stem to drop my bars slightly below the saddle. I have no legs and all upper body, when switching to 29 it was an interesting trick to fit a bike comfortably.

    He was giving the OP friendly flack for asking about a non-SS-specific item on the SS board. Happens all the time, usually accompanied by a wink and a giggle, and most frequently over on the 29er board.

    Personal preference:

    When I converted my bike to SS, I noticed that I wanted a shorter stem: I felt my weight was too far forward when climbing out of the saddle.

    Others may have different experiences.

    More importantly make sure it is a 29er compatible stem. 26er stems work but often fail due to not being designed to cope with the higher torque required on a 29er.

    Dunno about that in this case... the question is really about stem length, and some find they want a different cockpit/riding position for SS.

    I run a 100mm zero rise now but am going to a 120mm six degree rise on my Inbred (has shorter TT). I find I like to be more stretched out over a bike and get a drop bar feel is much more comfortable for me plus I get some serious speed on the DH.

    This is a good point.

    Zinn’s book has good reference on TT length and dialing in the saddle position to stem length. I even emailed Zinn to further define the math. It’s certainly a ‘feel out science’ in my experience. I am more inclined to dial in my TT length more precisely than stand-over height of a frame. I’ve ridden 16”, 17", 17.5”, 18”, and 19”. On the 16” I have to slide the saddle position all the way to back and purchased a longer stem. Similarly, on the 19” I had to use a shorter stem length. It’s all about finding that sweet spot IMO.

    My Unit came with a 105mm and I hated it. I replaced it with a 60mm and everything felt WAY better. I can't belive that so many SS folks still use 100mm+ stems! Whatever works for you I guess...

    +1 for me. A little shorter and a little more rise than my other bikes to keep me from "hunching" too much on long climbs.

    +1 on this. High or low, my bars need to be where I can stand and pedal straight legged, without bending bending my torso. There are 4mi 2000ft climbs where I am, and you'll need to stand about 90% of the climb. Being hunched over for that time would kill me, and then I'd be walking.


    Additionally, I vote for short stems on 29ers. The steering is already slow. You stick a 100-110 stem on there, and it is glacial.

    I run a 90 now, and will go down to an 80.
