Saddles are a very personal thing. Often a cheaper model can be better than an expensive one so check as many as you can. If you like a saddle we do not stock please ask us for a quote.
Seatposts have a vital function to perform in holding the saddle at the exact required angle securely. To achieve this modest task, 2 bolts mounted front & back are essential. Single bolt designs are much less accurate and also insecure, avoid! Frames fit an array of different diameter seatposts, check yours carefully to avoid damage or slippage.
