Looking for a reasonably priced, reliable XC stem that's on the lighter side of the scale. :)

So doesn't need to be all out no expense spared weight weenie stem, but something thats light but will last and won't break on me.

I weight under 185lb fully geared, just do XC, no jump or drop off (for more than a few inches), ride a carbon HT 29er. :)

Kalloy UNO. There's a million topics on that stem all with very good outcomes :)

I read about them for road, they are good for MTB as well?

Absolutely. Pretty much the default WW value stem. Only other real light and cheap option I found is Lyti from Dulight.fr

Very happy with my UNO, 70mm and came in at 94g, dropped that to 88g with a Tibolt set for £10 off evilbay (used the bolts from the Uno to swap out the rusty ones on my commuter, so it was a good value swap).

I'll add one point, longer stems put your weight forward, relative to your front axle and front tire contact patch. The more forward you weight is in this regards, the more likely you are to tip over the front of the bike - or endo. Way back in the day I had an xc bike with a 140 mm stem, and I thought it was so cool. I went over the bars like crazy on the thing, riding that bike was a death trap.

Syntace F109 is also a good choice and won't break your bank.
I have it on 2 bikes and can recommend it.

No issues with my Uno in -17 120. Never felt a lack of stiffness, good clamp, it does as it should and holds the bars to the fork.
Don't take me too seriously. The only person that doesn't hate Froome.

road stems work for MTB's. There is little difference apart from the angles.

XC riding does not challange the structure of a stem on bit.

I'm currently using a Hylix stem, bought from eBay. Probably not used and tested by as many riders as the Kalloy is, but it is a bit cheaper, and I think it's also a bit lighter. I've had no problems with mine, but I'm not really hard on parts though.

Interesting. That's scary light for the price :)

That Wren stem is definitely nice for it's price! Do you know if the weight is listed with steel or Ti bolts?

For UNO stems, what's the difference between "6" or "7" (or any others)?

Are they they difference in rise?
