The Masterpiece is Thomson's ultimate seatpost. It combines incredibly light weight with the characteristic strength and function of a Thomson. Masterpiece seatposts weigh approximately 40 grams less than an Elite seatpost of the same size, while maintaining high strength and durability.

Key Features
  • Over 40% stronger on ultimate strength test than the strongest production seatposts on the market
  • Weigh approximately 40g less than the same size Elite post
  • Machining all over, including the oval inner diameter
  • Certified to: EN 14766 2006 MTB
  • Integral-machined from one single piece of high strength 7000 series aluminum
  • The head is not pressed or bonded in allowing for superior strength and minimum weight, allowing higher strength at low weights
  • Natural ellipse bore inside tube for optimum strength to weight ratio
  • Long (41 mm) seat rail grip length helps prevent seat rail bending from impact loads
  • Incorporates a bending fuse to prevent catastrophic failure
  • Clamp, head, and upper tube are strong enough to withstand 325 foot-lbs of torque
  • Infinite tilt adjustment -5° and +29°
  • Very low profile clamps means no seat interference as the swivel nuts are down between the seat rails
  • Impact absorbing clamps - clamps, head, and assembly will spread and flex on impact to protect seat, rails, seatpost and rider
  • Adjustments can be made to the tilt of the seat without moving the seat forwards or backwards
