Customer Feedback

The little 45 page book is a treasure and really raises your awareness. There may only be 45 pages of information - but it's because it cuts out the BS and brings the benefit of a huge amount of experience. There is a clear avoidance of impractical "perfection" - yet the recognition that when you find your optimum even a couple of millimetres can make a huge difference.

Thanks for a fantastic DIY guide – I (slightly) injured my knee last week due to a combination of a new saddle (12mm lower height from the pad to the bars), sitting further forwards on a seat set up with a ~5 degree slope, and tight winter leggings. I’ve sorted each problem out, and your guide has allowed me to check a new seat height set-up and to measure the impact of forward/back position on the inclined saddle in less time than it would have taken to get down to my LBS for a fit.

Thank you for publishing your wonderful bike fit guide. This has answered many questions I used to have on bike set up. I must admit I have not gone through the whole process as you describe, but even following a few of your pointers I am already far more comfortable.
