    Stack height: Less than 30mm


    Length: less than 120mm

    Rise: less than 20 degrees

    Price: less than $50

    thanks for your help. links to specific retailers site would be really helpful.

    You actually had me wondering if I was confused, but Salsa says, no, you might be confused.

    Stack height pertains to your headset. The mountain bike stem is the component that clamps the handlebars in the center and attaches them to the rest of the bike.

    Your stem has a length and a rise, and you can go to any of the on-line retailers to find one in your price range. Performance, Nashbar, ebike, or google "bike stem"

    On the other hand, if you also need a headset of less than 30mm, search for "headset" - but they are 2 different parts.

    He means clamp height. OBVIOUSLY.

    Thanks for the clinic though, I feel much smarter.

    Gastro - I didn't even think of that! I was just thinking back to the headset ordeal Salsa had with his headset & head tube milling things, and wondering... is my memory failing THAT bad??

    Clamp height, though... does that matter? Can't you just trim the steer tube?

    Steer tube? What is that, a hot dog?

    My guess is his steerer tube is too short already - I'm pretty sure there's no way to trim it longer.

    Gastro, give her a break, she's just trying to help. Sherpapeak, I would've suggested a Thomsom stem, but it's out of your $50 range. For that price, I'd suggest a used stem on a public web auction site
    Why is going slower harder?

    That's a pretty short clamp/stack (whatever you want to call it ) height...

    Some of the older Salsa steel stems *might* be short enough. There is also an older Avid stem, the SAAGO that was designed partially with short steer tubes in mind. If you can find on, it may work.

    Otherwise, you're likely going to need a longer steerer tube, or a shorter stack headset to free up more tube length for the stem to grab... or possibly even have some off the top of the headtube faced off; though that won't likely safely gain you enough to do much good.

    Go here. They have a large selection, and they list many of the clamp heights.

    The hot dog comment was actually a reference to the hilarious head tube milling thread you mentioned above.

    I actually stole the term "stack height" from pricepoint.com....they list the stack height for most of their stem.

    Gastro gussed it right. I have a steer tube that probably 5 to 6 mm too short. the stem I am using currently is a two bolt design with 45mm stack height. and the steer tube ends just were the top bolt (stem) is located. I have not felt any problem with this set up on the road. But, I am not sure how safe it is on the trail. So. I figured If I could get a stem with smaller stack height, I could gain probably a good 10mm and that would solve the entire problem.

    Also, the bike has a fairly new headset, but the stem is pretty old and I am itching to buy a new one.

    Thanks gastro.

    "My guess is his steerer tube is too short already"

    you guessed it right. my steerer tue is too short.....

    "I'm pretty sure there's no way to trim it longer."
    it would be worth trying it though. who wants to be the brave soul.

    I'm just gonna hide back here in the holler & hope the dogs will attack any roving attorney (ninja or otherwise). All they seem to be good for is chasing flying birds.... but, hope springs eternal.

    Cool. There is so much going on in that photo.

    Interesting link on that page, I might add - after watching the video, the term "fruit booter" takes on a whole new, terrible meaning.

    I had to look for it, never noticed that before, now that it was pointed out, it makes the picture even nicer. I've heard Norway has some great riding when it isn't covered with snow, it's up there on my to go to list.

    Look for a little brown squigly line on the right side of the picture then slowly look up.

    Yes, unfortunately for us here in the US. I am a huge proponent of nudity in general, and more particularly the cycling type. An erstwhile occasional participant myself, I was there at the Mt Snow World Cups in the 90's for the (in)famous nude crit.

    It was only the rollerblader I found disconcerting - Truth be told, I hadn't ever seen that before, exactly.
