Uncannily close The "fit" that I was offered was extremely close to the "fit" I have been successfully riding. Within the margins of measuring error of the human! The ability to then play "what if" with some of the measurements (principally the seat post height) was interesting and matched some of the guidance and notes offered with the fit. Ultimately - when I used the "suggest a bike" feature and was offered the exact bike I had purchased 4 months before - I had to laugh. Great minds think alike (or we are both fools!)

Nice Service will be very helpful if the customer can choose the bike size edit 20230313: just got reply and the size can be edit, I just not aware, so this is very useful service.

The bike fit itself seems accurate and… The bike fit itself seems accurate and straight forward. Besides that there are some weird loops on the website that gave the impression of a not well maintained site.

Great value for basic bike fitting Everyone with a road bike is usually pretty much capable of doing the basic measuring (and has the tooling). This site provides the important calculations that you need to do the basic fitting yourself. Especially useful if you buy a second-hand bike! My personal experience is that I was able to check on 4 important points and did some changes, with as a result, wayyy less hurting from long rides.

Very good application for bike fitting purposes! The application is easy to use, the results are very helpful and the settings are well explained and easy to implement. However, the recommendation for the frame size differed significantly compared to what my bike dealer had suggested for a Cube Attain GTC Race. I have two suggestions for improvement. 1. It would be good if old results would be stored in the user account and could be viewed/opened again. 2. It would be great if you could enter frame geometries (at least the important lengths and heights) for a frame recommendation.
