    What size stem are you running on your AM rig?

    Just curious what everyone is running on their AM bike. I have a Santa Cruz Butcher with a 70mm stem, but I'm planning to downsize to a stubbier yet beefier (0 rise) 50mm stem for more aggressive riding with lots of air time.

    70mm on my Reign X, seems to be a good compromise for the trails. I have a 50mm I will throw on for DH days.

    -20mm stem with a 90 degree rise. Compliments my 847mm DH flat bars on my 4" travel Deluxe AM Trail Bike.

    Stem length questions on websites make me nervous as it's more of a personal fit/preference issue. It's like asking what size shoes everyone is wearing because of some wierd phobia of not having the size most people are wearing.

    I built up two 'All-Mountain' bikes with ETT's within .2 inches of each other but ran a 65mm zero rise stem on one and a 75mm negative 6 degree rise on the other as the bikes fit differently even though they were almost identical in size and travel.

    To throw up a number like most have done here is no different from the homelessman shouting at the light pole in the cold. It makes no sense.

    Ride with whatever length stem is most comfortable as far as fit/your 'style' of riding.

    But just keep in mind that if it's over 90mm long you will be gang raped.

    Personally I think that back inclination is the same when your hands are moving trough the arc trajectory - that's when you riding seated

    Oh, I guess I missed all the response requirements posted up in the two sentence OP .

    But thanks for translating and clarifying the question and policing up anything that you deemed inappropriate for the class.

    BTW, I still think it's a stupid f#cking question on par with the 'what does AM mean? threads that pop up daily in this forum.

    I'm running a stem that is 80mm with my sixc bars, I have thought about going for a shorter one but dunno if that's a good idea with my height (6'1") and my bike being a 19" model...

    everybody will feel comfy with a different length and rise though...

    90mm x 10 deg stem and flat bars. Rocky Mountain Rumble larger frame is pretty compact (for my 6'2") so its (barely) enough to allow me to get stretched out / provide room for climbing. Could go longer, but manuals would be harder. Could go higher, but it would feel like a beach cruiser (plus I like to weight the front for corner carving).
    With a longer TT, I'd probably run a shorter stem, but be unhappy with the amount of weight I can put on the front wheel.

    will a longer stem make a bike with a short TT more stable in high speed? I have a 70mm stem in my SC Blur LT2 and I was wondering if using a little longer stem will add a little more stability when going fast downhill as right now it's a bit uncontrollable....btw, I'm 5"7 in M size frame and I run a Chromag 29" bar....

    I would have a look at your body position before I bothered messing with the bike setup for what you described.

    Elbows out? Knees bent? good attack position?

    Decent video on the topic.

    70mm as I think for the most part that's the sweet spot if the frame is the correct size for your body.

    cheers for the video, I'll have a look asap, but yes, maybe it's a problem of my body position rather than the stem length although I'm comfortable both climbing or going down, just I feel the bike a little uncontrollable in fast downhills...maybe I miss the stability and longer travel of my dh rig....
