thomson x4 stem 50mm
I’ve got a 50mm X4 and its remarkably well made quite unlike any other stem I’ve owned. Its such a good fit on the steerer the bolts barely need tightening and the same for the bars just snug the bolts and theyre not going anywhere. Goes without saying there are no creaks or anything like that
Really nice precision bit of kit recommendedPosted 4 years agomikewsmithSubscriber

They’re both silly expensive, the Thomson’s heavy, and neither of them does anything that a Pro FRS costing £25 doesn’t do just as well.
BS the Thomson can use a gold face plate to match the rest of your finishing kit. Nice stem, like it nice and stiffPosted 4 years agojimjamMember
Thomson X4 is a thing of beauty. Better made than anything else on the market. It might cost £60 but you’ll easily get £40 if/when you ever decide to sell it. You can buy replacement face plates too. Fair enough the 3mm bolts can be a pain if you leave them but an upgraded bigger bolt will sort this out.
The Renthal is nicely made but somewhat flexy, and a pain if you need to work on your cockpit in a hurry, say at a race.Posted 4 years ago

A sure sign that you’re over tightening it!
You should tell Thomson they’re wrong- they say it’s just perfectly normal for a faceplate to fatigue and crack in use, and they should be considered consumables.
The rest of the industry doesn’t seem to have quite caught up with this top-quality approach, they all think faceplates shouldn’t crack… losers 😉Posted 4 years agoduirMember
It hasn’t happened to me, but yes that is their warranty response- replacement faceplate, and “perfectly normal”.
(only issue I had with my Thomson stem was that the 4nm maximum torque wasn’t enough to hold the bars in place. It was nice otherwise)
Very surprised to hear that. My Thomson X4 is 4 years old, has been on 4 bikes including a DH bike frequently used at Fort William. On my current bike, which also get’s hammered (and crashed sometimes!) I fitted it, torqued the bolts evenly with a good quality torque wrench and haven’t touched it since. It is my fourth Thomson stem and second X4 and I have never had bars move or seen a broken faceplate.
Seems to me to be a top quality piece of kit that will last for years and years but like most things care is needed during initial fitting.
They don’t always cost loads, my latest one was brand new on offer for £44.99.
Renthal one does look nice though and if it’s of similar quality to their bars you won’t go far wrong.Posted 4 years ago
I guess the risk, due to the strong second hand market for Thomson stems, is that you’ll buy one whose owner was a bit overzealous with tightening.Posted 4 years ago
I’ve got 3 stems of varying ages – all bought second hand – and have had no problems with faceplates.
But there’s no smoke without fire….honourablegeorgeMember

After learning the hard way with the Easton Haven I’ll not be scrimping or gram counting in the stem department again. The 60 grams or so difference between it and the Thomson are hardly a big amount but one is almost comically flexy, the other as stiff as you could ever want.Posted 4 years agoratherbeintobagoSubscriber

That Syntace is likely to be stiff, though, especially given their unique-to-SyntaceDH tests…Posted 4 years ago
