Thomson Elite X4 Stem
A DH and Enduro worthy stem that's also light enough for XC and Cyclocross
A company that produces parts for both the aerospace and MTB industries, Thomson are renowned for the precision and meticulously detailed machining that goes into all their parts. Before droppers brought on the demise of rigid seatposts Thomson posts were some of the most sought after on the market. They continue to make fantastic stems that are strong, lightweight and will give your mountainbike a nice touch of bling.
The steerer clamp is 'knee friendly' - and Thomson confidently say that the X4 is the best combination of strength and weight around, making them perfect not just for XC but for Enduro and Downhill riders.
The logo on the X4 stems is reversible, meaning you can flip the stem and the logo will not be upside down. You can safely run this stem with carbon bars (though be aware of the torque requirements included in the instructions).
The 32-60mm stems have a tough looking, blocky appearance that looks great on Enduro and DH bikes while the longer stems have a sleeker appearance more fitting to an XC bike.
The Thomson X4 stem is certified to: EN 14766 2006 MTB and DIN CERTCO: 2006 MTB. Built and tested to the same standard as Thomson aerospace parts.

Buy something else with better bolts.
by Gerard Ryan
Good stem. I rate other products higher. Ie raceface turbine etc. my main gripe with this stem is the m3 bolts and 3nm torque spec. Although more and more mtb riders own torque wrench’s they aren’t common place and certainly when one decides to move the stack or rotate the bars a little without said torque wrench rounded bolts and ensue. Do not recommend and would not buy again.

Was a bit sceptical being a pricier stem, but my handlebars and seatpost were Thomson so my OCD chose this one. Absolutely stoked with the quality, the finish is stunning, really makes you bike look classy and high end.
Couldn't ride without. Biggest change
by OTB -
Couldn't ride without. Biggest change to riding speed. Faster up and much faster downhill. Well worth the added weight. My seat ht moves almost more than my gears on many tracks. No more compromised seat ht. Functions perfectly and has no slop. Setup remote so that lever faces forward rather than rearwards. A bit harder to operate however for the frequency of my OTB adventures I would fear a rearward facing lever as suggested.

Superb quality as usual from Thomson. Going from a 90mm stem to a 50mm has transformed my bike. Awesome.
