Thomson has a fitting reputation for reliable, functional and lightweight components. In the same vein as Chris King, they take their time before releasing a product -- when they do, they"ve done it right. The Thomson Seatclamp is no different. Granted, most of us don"t consider a seatclamp a performance component -- that is, until it"s not performing. There"s not much worse than being on a ride when your seatpost is gently easing its way down into the seat tube. The Thomson Seatclamp represents the Thomson values in a sleek, simple, lightweight package. While they admit you probably won"t win a race because of it, Thomson engineered this beauty to perform -- the bolt is threaded at an angle, about 1. 5 degrees off-center, to help provide awesome clamping force -- they say just 20 inch-pounds on the fastener will suffice. It"s available in anodized black or silver in 31. 8 or 35. 0mm sizes.
