Quality Stem
Purchased this stem as an upgrade from the stock stem on my Trek Marlin. I was looking for something a little shorter, went with the 90mm Moondust Grey version. This dropped 20mm from my length and the Niner stem was significantly lighter than my OEM Bontrager stem. I'm really happy with the handling improvement and weight decrease. Good value for the price. Only wish the stem had a bit more of an aggressive look/design to it.

PROS: Easy To Install, Lightweight, Durable

BEST USES: Mountain Biking, Upgrade, Casual Riding

Very nice upgrade to my stock stem
Great upgrade to my stock Bontrager stem. Stinger, lighter and with slightly different geometry. This stem along with my new 31.8" bars really gave me the feel and control I was looking for

Good looks, relatively low weight
I paired this stem with a Niner RLT-9 frame build. It looks good, matches the bike (red stem and red accents on bike) and I purchased it for a surprisingly low price from Jenson. It is relatively lightweight for an alloy stem. I have no complaints.

Weight: 132.5 g for the 100mm stem that I purchased.
That's not far from the generic "129g" weight that Niner provides on their website without actually specifying which stem length they are referring to.

Another great buy from Jenson!
Great quality, light weight stem. Saved me nearly 6oz over the stock stem on my Fuji Tread gravel bike. Weighed in at 131 grams on my postal scale. Jenson continues to be my "go-to" spot for over 16 years now, since 1999.

PROS: Attractive Design, Lightweight

BEST USES: Cyclocross, Road Biking
