Thomson Seatpost Compatibility for Larger Diameter Saddle Rails

Thomson's standard rail clamps can accommodate rails up to 7 x 10mm, but riders using their setback post with oversize rails (larger than 7x10mm) may have issues getting the saddle nose into proper position. Ideal for downhill, BMX and carbon-rail saddles with larger diameter rails, Thomson's oversize rail clampset will provide roughly 5 to 8 more degrees of nose-down adjustment. The oversize rail clampset is also more cosmetically appealing than the standard clamps paired with oversized rails.


  • Compatible with carbon rails
  • Compatible with any of Thomson's vintage Elite or Masterpiece seatposts
  • Provided 5 to 8 additional degrees of nose-down adjustment
  • Saddle clamp bolts sold separately
  • Available in black or silver finish
