The design team for the new Thomson 31.8 stems had a tough goal: make a stem better than the Thomson Elite Road and Mountain Stems. That was a tall order, given the popularity of the Elite models. They’ve done it, though - the new X4 is stronger AND lighter than before. It’s designed around the 31.8mm bar standard for increased stiffness and strength. The X4 incorporates a new steerer clamp design that shaves 20 grams, and of course, the beautiful design and machine work that have made Thomson famous, with a knee-friendly clamp and no welds to break. OK for use with carbon bars (always follow the mfrs. torque specs).
  • 90 degrees (0 degree rise), 100 degree (10 degree rise)
  • Weight: 166g (100mm)
  • 7000-series aluminum
  • Steerer clamp: 1 1/8
  • Stack Height: 40mm
  • Bar Clamp: 31.8mm

        This stem has a simple, strong, functional design. The machine work is beautiful, my only gripe is the glossy black finish. I got this stem in 70mm.

          Comments about Thomson Elite X4 Mountain Stem:

          I can't say I know too much about bikes but through my few months of owning this stem I have thoroughly enjoyed it. I use to run a 110mm stem and although the turning was smooth I found I needed a more responsive feeling and switching to this X4 100mm stem I have noticed the difference and have put it to good use in my nearby singletrack trails.

            I ride my mtb on street but have many BMX days behind me. Excellent stem, strong & pretty... the 70mm/0 degree rise draws me in closer for a more responsive front end... sweeeeet!

              Was running a Ritchey stem with King headset and Niner carbon rigid fork. Had consistent problems with stem loosening on the carbon fork resulting in loose headset. Changed out to the Thompson and haven't had to tighten it since...

                I love this stem but found the fasteners had a very shallow head when torquing them my bit kept wanting to work out only thing keeping this from being perfect.

                  This stem completes my mtb trio with the elite seatpost and black seatpost collar to match. This stem is lighter in hand than it looks, shows the usual fine machining Thomson is known for (just look how thin the front plate gets). Felt great at each point during the installation. And, in the end it has a slick, aircraft-precision feel to it.

                  Thomson has a reputation for excellence, so this review will not be a shock to you. Just another satisifed customer who likes the flawless function of the X4 stem. There are other stems that maybe look a bit cooler but this has passed the test of time for me.

                  I have been using the X4 for about 4 years now and I am still on the same one. It still looks and feels great. The finish is nice and clean. Thomson is like Chris King...you get what you pay for.

                      Comments about Thomson Elite X4 Mountain Stem:

                      I purchased the 50mm with zero rise. Much beefier and stronger than the stock stem on my Giant. The small allen bolts are to achieve the correct torque for the stem, not allowing for over tightening on the bars and the steering tube. Also, steering tube should go through top of the stem 2mm-3mm for correct torque on the top bolt. (run a 5mm spacer and then top cap on the top of the stem) Info posted on Thomson's website (blog). Great product and cutomer service from Thomson!
