Cycling Weekly Verdict

The Bisaddle could be prayers answered for anyone who has struggled to find the right saddle or who suffers from pain. The patented adjustable system - which BiSaddle says is the world’s only - is user friendly, solid and reliable and most of all, really clever. However, it's very heavy at 400g and you need to pay a lot of money for the lighter top-spec version with the carbon base; the jig-like appearance won't suit everyone's race bike and even at its widest this model can't match the sitbone width of some women-specific standard road saddles. If it's just the weight and aesthetic that puts you off, it could still work well indoors or as part of a bike fit solution.
