About Us

Graeme* started out teaching spinning classes at a number of what used to be Health & Racquet Clubs (the number one gym group in South Africa, now called Virgin Active Gym Group). He also presented Master Classes on Indoor Cycling and new Spin Instructors training for the Health & Racquet Club. 

The next step was to open his own spinning/indoor cycling studio and The Crank Shop was Established on the 11th of May 2001. The only indoor cycling studio of its kind.

What would set The Crank Shop apart from all other spinning classes? First, the studio was equipped with new stationary bikes that had a click resistance system so that levels of resistance would be equal (much better than the turn dial system that was being used at the time). Second, all bikes now had a computer system so that speed, distance and other variables could be monitored (this was also unavailable on current spinning bikes). Third, Pedal Systems were fitted, and these took cycling shoes with cleats. Furthermore, a new Teaching System (The Recovery Card System) allowed new bike riders, fitness enthusiasts and advanced bike racers to all benefit in the same class.

Clients quickly understood and enjoyed the new way of indoor cycling classes and membership grew to in excess of a 1000 members in year one. Three years later it was time to upgrade the stationary bikes to indoor cycle trainers and members brought their own bikes to classes and experienced the next level of indoor cycle classes.  Some of the great benefits of this were having the comfort of riding one’s own bike (correct set-up and seat) preventing unnecessary injuries, and learning to change and use all gears (giving a much wider range of efforts and speeds improving condition, fitness and health).

So what would be next …

It was time for The Crank Shop to design and manufacture its own indoor cycle trainer. 

  • A trainer that would be fun and that could be ridden by all.
  • One that would improve fitness as well as skill.
  • trainer for home, office, and studio use.
  • One that would take a complete bike and give a real feel ride. 

The TrailShreda TM was born.

We hope that you will enjoy the No.1 MTB Training Aid as much as we are.

To happiness, health, fitness, speed and fun.
