Zendurance & the Guru Dynamic Fit Difference

Guru's Dynamic Fit Unit promises to revolutionize bike fit
Montreal-based custom builder Guru Bicycles introduced what was easily one of the most talked-about non-bicycles at this year's Interbike. Guru's new Dynamic Fit Unit integrates RacerMate's Velotron-derived computer-controlled eddy current resistance unit into an adaptable chassis with adjustable handlebar and saddle positioning. All of RacerMate's standard functions are built in, including power output, cadence, heartrate, speed, distance, time and calories, and the SpinScan pedal stroke efficiency program.

In Guru's case, though, all of the adjustments are computer-controlled with precision stepper motors. As such, the rider's position can be continually altered in order to optimize each of the performance parameters (which are displayed in real-time on the computer screen) without even having to dismount between changes.

Once the fit is optimized, the X-Y coordinates of all of the key contact points can be instantly recorded so that the position can then be replicated on the customer's actual bike. If a custom frame is in order, the numbers can even be immediately uploaded to Guru's servers in Montreal which can then send back a proposed custom frame geometry before the rider even gets off of the trainer! The only thing left for Guru to do in order to deliver truly instant gratification is to figure out a way to send the actual frame via email. .
