    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

          Very nice quality alloy stem. What you would expect from Niner. Feels nice and stiff even at the 100mm length.

            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.

                  Comments about Niner Alloy 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.

                  • Q:

                    Any idea what the stack height is for this stem? I'm trying to fit a thule baby seat to my mtb. and I'm looking for a stem with a smaller stack height than my current set up so that there is more spacer surface to mount the bracket to.

                    Thanks in advance,
                    Chris
