    Stem length on Superfly 100 21"

    I just picked it a brand new 2010 Superly 100 this week. I'm 6' 3" and I'm feeling like the 105 stem isn't enough. Pre-road my friends 2011 with a 120 stem and it felt great. Anyone else switching out to a 120. My reasons are it feels very quick to turn and the cockpit feels short. I think the 120 will give me more room and settle down the twitchiness a bit.

    Anyone else have similar experience with their bike?

    Weird thing is the effective top tube is supposed to be greater than my other bike which I run a 120 stem on but this bike measures out about 1.5" shorter handle bars to seat than my other bike so I'm pretty sure I need the extra 15 mm.

    I have an older 21 inch sugar and I switched to a 120mm stem. I'm 6'4" and I think it made a pretty big difference. The steering doesn't feel slow just not quite as twitchy. I also feel like I'm in a more natural position and not as cramped. Also the bike is way better on the climbs. No more popping wheelies. Hope this helps.

    I'm not popping the front end on climbs but I feel cramped. I ordered a 120 from Crank Brother and looking forward to trying it out.

    I think you'll be happy with the 120mm stem. Forgot to mention that I didn't see a difference in descending. With the genesis or g2 geometry there is so much weight over the rear wheel you can afford to add a little stem length without changing the bike drastically.

    I just posted a couple weeks ago about a similar thing with G2 geom. Same ett length as my other bike but having twitchy descending problems with the G2 & 90mm stem. I initially thought a longer stem would make me feel too OTB & more prone to going over, but I tried a slightly longer stem (+10mm) & the bike feels much better. I really like the way that the bike handles now.

    give it a go....I think you'll like the results.

    21" Superfly 100, 80 mm Stem

    I am 6' tall, with a long torso; recently purchased the 2013, 21" Superfly 100.
    After riding about 20 miles with the 105 mm stem, my lower back hurt, probably from being too stretched out. The 19" frame however, I felt a little cramped. I put a 80 mm stem on the 21" frame and it feels a lot better. On the other hand the 29er wheels and higher seat tube, makes the bike feel high off the ground. The 19" frame felt like it may have more control and is easier to get on and off because the stand-over is shorter.
    Do you think a 21" frame is too big for a 6' tall person?

    I am 6-1 with 21" frame and 90mm stem. Feels right to me. Used to ride larges but like the xl better, no seatpost length issues especially.

    I think the bike can feel short because of the sweep of the bars. Good old 5 deg straight bars might change the feel.

    I am just a little under 6' and ride the 2010 superfly 100 17.5 with a 20mm setback seat post and 100mm stem with 5 deg bars. The 5 deg bars are a lot more forward than the 12 or 17 deg. I tried the 19" but it just felt big.
