Product Details
✓4-Link Suspension - The patented parallelogram structure, unlike the central compression used in most entry-level suspension posts, achieves pressure balance for a softer and more comfortable riding experience
✓Extreme Capacity - This suspension seatpost is designed for riders weighing between 50 and 130 kg (110 and 290 lbs), with a maximum capacity of 150 kg (330 lbs). Note: Riders over 130 kg (290 lbs) may notice slightly reduced suspension travel and a firmer ride
✓Specification - Length 365/580mm, Travel 50mm, offset 25mm, weight approximately 800g, made from 6061-T6 aluminum alloy, manufactured in Taiwan
✓What length should I choose? 365mm or 580mm? - 365mm: Suitable for seatpost lengths between 300mm and 400mm; 580mm: Compatible with seatposts measuring between 500mm and 620mm, especially certain folding bikes, such as Brompton and Dahon
✓Before Buying - Please check the diameter of your old seatpost to ensure you receive the correct new post.Some of the seatpost diameters listed are converted using a shim. For example, for a 30.4mm seatpost, you will receive a 27.2mm post and a shim (27.2 to 30.4mm), saving you the trouble of purchasing it separately. The shims are super-lightweight and essentially invisible once installed
