Hi,


What is the lightest stem for a mtb in 130mm you can advise me on a 29 xc bike ?
I'm 72 a 73 kg


Tx,
Ced

You'll only find light 120mm 31.8 stems, 130mm will be extremely hard to get light in that length.
Extralite makes them in 120mm, nice and light.
I'm running the UL3 for a few years now.

at 130mm on a 29er, keep an eye on STIFF too.
i'd go syntace, the new zipp ones seem pretty good. thomson is beefy but beefy, if you know what i mean.

thanks for your reactions ........


What would be the risc, if I d use this Extralite one ?
EXTRALITE Vorbau RoadStem OC Rennrad 31,8mm 99g @ 130mm

I wouldn't huck that drop if I were you...

Extralite-stems are strong, I've never heard of one breaking during use. They might not be stiff enough for everybody, but definitely strong enough for XC.

i would question the use of a road stem for xc, especially when extralite makes a separate xc stem. they make light stuff, and if it were xc worthy, i'd think extralite would state it as so.

I agree with thisisatest.
At extralite they really know what they are doing and their products are very good.
But using a Road stem for XC is not what it is intended for.
Especially when you use a wide bar it's under a lot more stress than with an 42cm road bar.
I'd really advise you to look for another brand that makes 130mm stems for MTB or go with an 120mm UL3.
I used the 120mm UL3 for 2 years on my MTB and had no problems with flex (i'm just under 70kg).

I do have a 130mm mtb KCNC at this moment, but would like to have a lighter one.
Weeks ago I did sent a mail to extralite, and they where not that negative regardingg using a road stem on an MTB.
Of course, legally wise, they would not be responsible if anything would happen.

On the other hand, as you wrote above, I will swap the KCNC 600mm bar for a Schmolke 680mm bar, so that will give a lot more force on the stem.........

The new Ritchey WCS C260 is superlight. Alloy & Carbon versions. Very clever - not sure about whether there's a 130mm, but defo 120mm. Ritchey stuff is great, been using his stem & carbon 'bars for years. Each model gets better and lighter.
