Description

The new Thomson X4 for Mountain and Road allow you to realize the benefits of stiffer forks and stiffer 31.8 bars. They offer precise steering, tracking, and more control while riding, all wrapped up in a beautiful design. The Thomson X4 is stronger and 30 grams lighter than the Thomson Elite 25.4 mountain stem. It features a traditional steerer clamp that is shaped to save weight and to be knee friendly.

Light enough for Cross Country or Road is only part of the story. The X4 is absolutely the best combination of strength and weight available. Thomson stems are the strongest in the industry, meaning freeride and downhill riders can run Thomson confidently. 171g (110mm). 0 or 10 Degree rise. Fits 31.8 bars.

Solid stem

I bought this for my road tandem, replacing a Thomson X2. The old stem had developed a creak coming from the faceplate bolts, and I needed to adjust my position slightly anyway, so I replaced the 120mm -17� stem with a 110mm -10� X4.

The new setup is significantly stiffer. I can't be sure whether the difference comes from the slightly shorter stem or the 4-bolt faceplate or both (although I suspect it is mostly the 4-bolt design). The handlebars feel significantly more solid when out of the saddle. Both the steerer clamp and the handlebar clamp on this stem are slightly taller/wider than on the X2. I had to remove one spacer on my steerer and slightly move my Garmin mount to accommodate the difference.

Looks cool and works like it should

Well what could go wrong with a stem? Not much. I've been using Thomson stems on my road bikes. Yeah I know its a mountain bike stem, but it looks cool. Anyway, it does exactly what bought it for. I screwed up o this on and bought one too short. I was building a bike and had a few old stems laying around, so I put a 120 FSA stem on this new ride. The other stems had some steep angles and the 120 turned out to be too long. I ordered the Thomson in a 90. That turned out to be too short. I can't win, but its not the stem's fault.

It's a big boy.

Thomson's reputation preceded itself here. I thought it would be crazy outstanding machining and industrial bling, but I was a bit disappointed to find the face plate doesn't line up perfectly with the stem body - a little off, but off - and it's a very chonky unit. I didn't weigh it, but it assumes quite a prominent presence on the front of the bike. I prefer a slim and light-looking front end. It's a decent piece and a sure upgrade from a regular $30 stem, but their rep is hollow. Live and learn.

Thomson stems are the best.

I currently ride 3 bikes with 3 Thomson stems.

2 Seatposts, only because my mountain bike already has a dropper post.

On every bike I own.

There are a couple of things you can buy for your bike and never worry about again.

A Chris King headset and a Thomson stem. As light as a carbon stem and 200X more durable.

Nice stem, good value

I was looking for a stem with a bit more rise in it. The Thomson stem fit my criteria and I've always ridden there seat posts and loved them for their quality and durability. The quality and finish of the stem are the same as that of the seat post's, second to none. The stem is also quite stiff and seems to be bombproof. I'm very happy with the purchase and consider Thomson product to be a good value for the money.

Power saver.

I bought this stem as an upgrade for my track bike. It's not the lightest stem out there, but it is quite stiff. That allows me to really put the power down in sprints, or hold a track stand with confidence.

Always dependable

I bought this Thomson X4 to replace one that my back was unable to take the lower drop anymore. I had a Thomson bolt break once and Thomson replaced it for no charge. Thomson produces excellent products and stands behind them.

Thomson - solid components

Some measure of vanity played a part in this purchase (I have a Thomson post).

I did want a slightly shorter stem - I am getting older and less flexible.

It's a quality Thomson part. Was easy to install. Had good directions. Looks nice.

I can't really say that I noticed any huge changes on swapping a stem. The stem is shorter, so I suppose I could say it is stiffer, but that may be more a result of changed riding geometry than the stem.

Completely solid stem

This stem does what a stem should do. It looks great, it's stiff and once installed you never have to think about it again. Make sure to follow torque specs and it will outlast the rest of the bike.

Simple, timeless and priceless.

I've built two road bikes and two mountain bikes using Thompson's stems and seat posts. They are the parts of the bike I forget about. These products are not flashy and bling which I like. They are all business and do their job with out fail. Everything about them from build, price and weight is above and beyond any other product I've used.

Fine manufacturing seems to be gone

I bought this as a replacement of my previous Elite X4, 100mm 0deg. I'm concerned to see how badly the plate does not align with the stem, but more so it there will be a gap on my carbon 1 1/4" bar. In addition to that the bolts are pretty bad - so I'll use my older ones. For the price I was expecting something far better.

Best stem you can find

I’ll be honest I’ve had a Thomson stem on each of my bikes for the past 10 years. These are by far the best stems on the market. Made is the USA as well. I have their seatposts and carbon handlebars on each of our bikes as well. Best looking cockpits in the northwest.

Very happy

Still kinda new to mountain biking, but I needed a new stem so I went for the best. Feels solid and seems incredibly well made. It also made my bike fit me much better, but that's probably more of the change in length. Still, I'm very happy with the stem (110mm) and would definitely recommend it to others.

Sturdy design, great weight, functional well made parts, and price make this a great stem for non-elite XC and all-mountain riding security

I ordered a custom ti mt bike that was to have a 110 vs 100 mm stem and selected Thomson 110 as the product of choice for cost as well as strength. There are less heavy stems out there but this was ideal for me. I have a Thomson setback seat post as well and am happy with that in terms of strength and design. Weight works fine for all mt as well as my sport class XC racing. Bolts, when torqued to settings described do not slip and I fell worry free that they will come apart. I had a really good fall too and the stem was intact and true. Their models also provide different degrees of tilt so you should explore their options. I like this product enough that I am seriously switching to this as well for my road and commuting bike. Bottom line for me- the last bit of my custom bike to be dialed-in was the setback seatpost and a slightly elongated stem. The choices in models available make this a great choice of stems for multiple use.
