Our new Retül Müve

I’ve returned from my holiday in Canada to a great new present: The Retül Müve fitting jig. This is a significant upgrade in our fitting department as it allows me to adjust the position in seconds while the rider never has to get off the bike or even stop pedalling.

Four handles are used to adjust the vertical and horizontal changes to both the bars and the saddle, with one turn equalling only a 3mm change. This means that I can make minute changes to the position and the process takes half the time as there are no clamps to be undone and no bolts to be done up. This means that I can spend longer fine tuning the mechanics of the rider. The system is also more accurate as the rider doesn’t have to get in and out of the saddle, which often leads to people sitting in a different part of the saddle.

The adjustable cranks on the jig have an even greater range of adjustment (155mm to a whopping185mm) and are quicker to change than our previous jig. So it’s very easy to show a rider what shorter cranks feel like. The Muve also comes with a Powertap built into the resistance unit. So we can do fittings certain power levels. I am going to experiment and see if it is accurate enough to show how power production is affected by crank length.....

In addition to the great Zinn digitiser and measure tool, the Müve has a neat trick to quickly measure the current stack and reach that is being used. This allows us to suggest which frame size would be closest to the current set up.

I have only been back for 3 days and already I have used the Müve during a road, triathlon and mountain bike fit and have been incredibly impressed. It’s stable and allows me to make three times the amount of measurements and changes in the same amount of time. It’s a big step forward for the Bespoke Performance Lab.
