Seems to work as expected

Reviewed in the United States on July 13, 2023

I was having an issue with my seat post creaking sooner and sooner between cleanings. It got to the point of my post creaking by the end of the ride. I noticed that my old clamp would slide up as I torqued it to spec. The frame didn't seem to have any abnormal wear so I figured it must be the clamp. I thought I'd try this one because it looked like a robust design. It is a nicely machined part with nice finish. I like how the bolt has a spherical head and washer so that the interface can articulate as the clamp compresses while it is being torqued. I used a torque limiting driver since the spec is only 2.8 nm. It has been weeks since I installed this after a cleaning and fresh application of assembly paste and there are still no noises. Very happy when things work as they should.

If you know bicycles, you should know Thomson makes some nice parts. They do not make oodles of bike parts, at least that I know of, appearing to specialize in stems, seat posts, and handlebars mostly (they do offer a bike, which I bet is nice). They make quality stuff and it is decently priced in my tightwad opinion. All the Thomson stuff I have is also made in the USA, which is a bonus (they do appear to offer a carbon handlebar from Taiwan).

The clamp came nicely packaged in a fabric pouch, and has a serious heft to it. The finish is nice and uniform, and clamped up with less force than expected (less than other clamps). I needed it for an older Cannondale M800, which was in need of a new clamp thanks to the old nylon washer of the original clamp wearing away to nothing. I do not need to adjust the saddle, keeping it in one position for my now older, slower riding style (I was slow all along, enjoying the scenery). If you need a quick release clamp, I suggest skipping this model.

It works fine and holds the seat post firmly in place.

Highly recommended!

Small part that does its job very well

Reviewed in the United States on September 14, 2013

Color: BlackSize: 30.0mmVerified Purchase

I built a mountain bike over the summer, which was a steel frame On One Inbred. It has a weird size for the seatpost, but this clamp fits it well due to the frame company not really accounting for paint thickness. When I got it, it came in a small cloth bag, which is great for organizing small parts later in, say, an under-saddle bag.

The clamp itself is very well machined, and if you can deal with it being slightly asymmetrical from above, makes for a very good clamp. It takes surprisingly little to completely lock down the seatpost. I'm definitely not a very heavy guy, but I can tell that this can take a lot of weight without letting things slip. Installation was easy, as it slid right on, and has a little lip on the inside to stop it from sliding too far down.

tl;dr This clamp does its job. May be a little pricy for what it is, but you get what you pay for.

Typical Thomson Quality

Reviewed in the United States on November 4, 2018

Color: BlackSize: 34.9mmVerified Purchase

The perfect replacement collar. Looks great and performs flawlessly. I've had others that are still in service ten years down the road. The bolt has not worn at all, let alone stripped, despite repeated tightening/loosening, switching from bike to bike, etc. Just pay attention to the torque rating: yes, it does specify a mere 2.8 Nm. I set my wrench at 3 and call it good. No problems with slippage or over-tightening issues. Ever. I wouldn't buy anything else.

Top Notch - Use a torque wrench!

Reviewed in the United States on June 22, 2013

Color: BlackSize: 34.9mmVerified Purchase

I bought this after I stripped the bolt on my old clamp, trying to get it tight enough so it didn't slip.

This works like a charm. No slipping at all. *Use a torque wrench*: 25 in*lb (~2 ft*lb or ~2.8 n*m) is not very tight, yet it holds very well.

Since you probably don't want to carry a torque wrench on your rides, set it with a (borrowed?) torque wrench, then loosen and tighten it to the same spot with your handy multi-tool to get a feel for it. For instance, I use a Blackburn Toolmanator 12 Multi-Tool , and it is just finger tight when you use two fingers to hold the tool.

If you over-tighten it, you will likely break something.

Does exactly what it's supposed to do!

Reviewed in the United States on June 12, 2019

I had a quick release seatpost on my bike, and it kept slipping down no matter what I did. I got fed up and after a recommendation from my local bike shop, I picked up this clamp. Now my seatpost is rock solid --- it feels like it wouldn't move for anything. I've even had my dad ride my bike around (a big tall football sized guy, at 300 pounds) and it didn't budge an inch!

Very good but also very expensive

Reviewed in the United States on September 17, 2019

Color: BlackSize: 34.9mmVerified Purchase

Product is great and looks gorgeous and hence rating it as 4. Because the reviews are all about how good a product is. Should we spend that much money into a clamp, is individual discretion. I have a carbon frame and didn't want to risk taking chances so went with one of the best. But maybe they knew this and so their product is marked premium. At the end of the day, it is just a clamp.

Typical Thomson top quality

Reviewed in the United States on February 12, 2019

Color: BlackSize: 31.8mmVerified Purchase

Top quality seat post clamp. Thomson has a limited catalog, but everything they make just works.

I snapped a bolt in my original seat clamp. My local bike shop sold me a leightweight clamp that couldn’t keep the seat post in position through 20 minutes of riding. Within a week, I ordered the Thomson. It has been bulletproof.

The sizing is based on the diameter of your frame’s seattube. I have an aluminum road bike with a 27.2 seat post. 31.8 clamp fits my frame.

26.8 seatpost binder

Sleak, but not exactly what I thought.

Reviewed in the United Kingdom on May 12, 2019

Color: BlackSize: 34.9mmVerified Purchase

Nice sleak design, but image is an little misleading. This looked to me to be half matt, half glossy finish, which is what attracted me. It still looks nice in full gloss though. I would recommend changing the 3mm Allen key bolt to a more standard size.

Also, the recommended torque is 2.8nm, I would only stick to that If clamping a carbon post. I tightened to 4nm on alloy post and have a nice secure clamp.
