The Thomson Seatpost Collar has several features that make it distinct. The collar utilizes the Thomson Seatpost bolt, washer and barrel nut combination that has proven strong over the years. This fastener combination allows float on both sides of the collar slot ensuring consistent clamping force. The bolt hole angle, height of the collar and offset slot all help create a collar that generates maximum clamping force at only 25 inch pounds of fastener torque. The Thomson Seatpost Collar is made from the same 7000 series alloy as our seatposts and stems giving you the high performance and long life you expect from a Thomson.
Great looks, great clamping, long life and no squeaking.
The perfect addition to your Thomson Cockpit. 100% American made.

Thomson Seatpost Collar
by Steve S. of Granite Falls, WA on June 6, 2022
Ownership: a few months
Tech Knowledge: high
The fit, finish and look of this seatpost collar on my bike is really nice.
It looks great with my Thomson seatpost and stem. It`s hard to beat Thomson quality products.
Jury is still out on this.
by David C. of Jackson, CA on March 11, 2021
Ownership: a few weeks
Tech Knowledge: high
Pros
Light and sleek looking.
Cons
If I had researched this clamp further before pulling the trigger on it I likely would not have bought it.
They use an undersized bolt (3mm) with fairly low clamping force (2.8nm) to achieve results. I have had to tighten more than that to keep post from slipping. Frame is prepped, good quality seat post etc...and no excessive grease, yet still requires more than recommended torque. Small bolt, bigger torque, potentially no good. I just switched to a different seat post with a textured anodized surface and trying again before throwing in the towel on this seat clamp.
Other Thoughts
Sometimes basic tried and true engineering ( it is just a seatpost clamp after all) is the best way to go.
Great during the warranty period

Product:
Thomson 31.8 Seatpost Collar - Black
Ownership: more than a year
Tech Knowledge: somewhat high
Pros
Seatpost didn't move.
I like the barrel nut design that won't strip the threads if you would overtighten the locking bolt.
Fast delivery from Modern Bike
Cons
Thomson has a three year warranty. I installed the clamp almost five years ago, and I noticed a crack in the clamp during my last ride. I only ride during the summer months though, so it is really like 2-1/2 years of actual riding time.
Other Thoughts
For the price charged, Thomson should give a lifetime warranty.
