The SR Suntour SP12 NCX Seatpost has been engineered and built for years of comfort and performance. The unique and patented parallelogram design allows for small bump compliance with a total of 50 mm travel to make for a nice and comfortable ride. Minimal maintenance and long-term durability is what this post is all about.
The weight limits are general guidelines to prevent excessive wear and tear on the moving components of the seat post. Customers of all sizes have made the seat post we sell work for them (provide enough cushion over most terrain).
Note that using this seatpost raises the seat height roughly 4inches or 11cm.
