Thomson's Elite Seatpost is perhaps one of the most recognizable bicycle components in the world and it has earned its reputation as a super-strong, light and reliable beauty. With roots in the aerospace industry, Thomson builds the post with a tough and light 7000-series aluminum body, an elliptical extrusion that adds strength and stiffness, and a head and seat clamp forged and machined from a block of aluminum to eliminate any possible weak areas. Plus, its simple-to-use 2-bolt seat clamp allows speedy, infinite and secure seat angle adjustment from minus 5 degrees to plus 29 degrees. Upgrade your favorite ride to a Thomson seatpost and start riding in style.

The Elite X4 Mountain Stem is instantly recognizable because of Thomson's legendary style, and with strength to spare, this stem is more than just a pretty face.

The Spyre is a mechanical disc brake that offers superior performance with incredibly easy setup. This is a dual-piston-actuated mechanical disc brake caliper that provides precise clamping force. This translates into even pad and rotor wear, because the rotor does not need to flex to one side during braking. We added a simple cable barrel adjuster to make fine-tuning easy. All of this in an incredibly thin 40mm, 146g package that works with any drop bar levers on the market. Rotors and adapters are sold separately. For tandem bikes, we recommend the Spyre caliper paired with our 2.3mm thick rotors. This will give optimum stopping performance for you and your partner.
