Indoor Cycling Studio

Stay in great shape This Winter!

Indoor Spinning Classes at Chain Reaction

Located at 4231 B Dundas St W (above our store), our indoor cycling studio is the first of its kind in Canada! We have 12 Cycleops Club 300PT Power Tap-equipped spin bikes. These bikes measure power output (watts), cadence, heart rate and calorie burn rate allowing our qualified instructors to give you a better workout that is more accurate and precise. Power-focused training is the ultimate way to get an amazing workout! You can even use the Cycleops proprietary USB storage device to record your workouts! Free software lets you keep track of your progress.

Beginners welcome!

Call us to ask about the studio, the bikes or to book your classes.
