Thomson Elite Setback Seatpost - Black / 30.9mm / 410mm

Elite Seatpost Setback Black The Thomson Elite seatpost is over 40% stronger on ultimate strength tests than the strongest production seatposts on the market. The Elite has double the fatigue life of any other production models tested. The tube and head of the Thomson seatpost are integral-machined from one piece of high strength 7000 series Aluminium. The head is not pressed or bonded in. This allows for superior strength and minimum weight. It's incredibly lightweight, approximately 201g (250mm length) for road bikes and 228g (330mm length) for mountain bikes. The natural ellipse bore inside tube creates an optimum strength-to-weight ratio. We have a long 1. 614 inch (41mm) seat rail grip length. This helps prevent seat rail bending from impact loads. Most other seatposts have grip lengths of at least 0. 5 inch shorter than our grip length. The Thomson seatpost design incorporates a bending fuse to prevent catastrophic failure.
