    PWhat lenght are you looking for and what size bars, 31.8 or 25.4? If your looking for a 50mm stem I'd suggest the renthal dou, its lighter than the Thomson, weight is @ 135grams.

    Split second stem is awesome. They make a 50 and a 70.

    Point One Split Second Stem. Besides lightweight, Point One Split Second Stem is also one of the highest strength to weight ratios in the industry (beats Thomson).

    The 50mm Chromag Ranger is hard to beat at 140 grams. Its small and so well made worth the money.

    its hard to go wrong with any high quality stem, basically pick the one that gives you the length, weight, and bling you want.

    mhmm, yeah forgot that. with people throwing around thomson, easton, point 1, etc i kinda figured price was irrelivant. honestly for the money truvativ makes the best stem imo.

    Not sure on availability yet, but the Syntace Megaforce 2 seems to be a follow-up to their Superforce stem, which itself is pretty damn dialed. I'd take either over a Thomson in a heartbeat. Short of Syntace, I'd probably just go with the Truvativ AKA.

    1. Renthal Duo
    2. Point1 Split Second
    3. Thomson.

    I have all four ( both the 50 and 70mm Point1's)

    I like the Renthal best. A bit fussy to install, but light, no flex, a bit of rise that helps with the Easton Havoc Carbon bars low rise and it looks awsome.

    Hope you have a good health insurance policy (I've never seen any of their junk make it a full season but YMMV if you just use it for AM).

    Haven't seen Black Market mentioned - they don't sacrifice strength with their stems. I wouldn't hesitate to use Chromag, Thomson or Straightline either but they're quite a bit pricier.

    Have FUN!

    Holy crap, what is the world coming to? Pictures of stems on scales in the AM forum? Are we really doing this?

    My recommendation of a strong stem I have experience with is Thomson. It's a proven design and I've been happy with all the ones I've had.

    I agree. I bought a couple of Truvativ AKAs a while back to play with stem length. Found the length I liked and just left it on there. They're a little heavy, but for $30 you can't beat 'em.

    Truvativ AKA...buy a couple lengths, see which feels best. Solid performance and great value. 60 and 70mm lengths. I kept the 60mm

    We both desire properly-engineered parts, and the scales help us get a bearing on strength-to-weight ratio. We aren't fretting over a few grams...you were fretting over pictures of item weights.

    Another Truvativ AKA fan, so long as you are okay with 60mm or 70mm. Not crazy light, but not stupid heavy. Wide clamping surface. Nothing fancy, but they are relatively cheap, and just plain work well.

    For a 50mm, I'm a fan of the Sunline on one of my bikes.

    If budget is no object, then get what looks nice and is light for your ride.

    You can't determine strength to weight by a picture on a scale. You actually need to know strength to do that. If you're interested in pointless numbers that you can give an imaginary relevance then go hang out in the weight weenie forum. I'll happily take function over weight any day as should be the focus of anyone who is actually out there riding and probably abusing a bike.

    There are lots of great suggestions so far that are hidden beneath the horde of people posting whatever they find in an internet search that weighs the least. If the question had been, "what is the lowest weight stem you can post?" then this would be a relevant direction. Instead the OP (eventually) asks what the highest strength to weight ratio is and since none of us have actually taken any stems to failure in a lab maybe we should focus on strength instead of focusing on weight. Perhaps you have a better idea? Just buy the lightest stem and strength be dammed? As much as I hate the label "AM" it can be assumed that a rider in this category is not as concerned with weight as they are with durability and performance whereas an XC rider may be more inclined to weigh their tire options before they pick one. Aren't we better than that?

    Of course I will concede that at least we can find numbers on weight comparisons which is far more than we can say about strength. But be assured that no information about strength can be ascertained through weight. As a classic example search the Tacoma Narrows bridge. Civil engineers at the time wanted to increase the strength of the bridge so they beefed it up. Didn't go so well though...

    My initial comment was made as a teasing comment but you're really into this so it means I get to play poke-a-troll! Yay!

    Yes. The Syntace has failed on a few people. I can't find the threads now but if you search a little.
