25 years experience

Since the foundation of Radlabor in 1997, we have been concerned with the further development of measurement methods and their translation into individual seating positions on the bike. Our origin is the Olympic Center Freiburg-Black Forest and the Sports Institute of the University of Freiburg.

As one of the first centers we dedicated ourselves to the optimization of seat positions, also called bike fitting, for top athletes. We have not only perfected measurement methods and systems, but also developed them ourselves.

Today we are able to advise everyone individually with our expertise, whether it is to reduce pain, to get more out of sports or to lose weight.
Smartfit combines scientific competence with years of practical experience from three own service centers in Freiburg, Munich and Frankfurt.
