How do I get started on PowerCranks™?
We suggest that you use a stationary trainer for the
first few sessions on PowerCranks™. This allows you to get accustomed to
the different neuro-muscular sensations. Furthermore, we suggest that you not
attempt high cadence. It is better to focus on pure form. Once you can comfortably
ride PowerCranks™ for 5 minutes non-stop on a trainer, and once the strange
feeling has faded away, you are ready to take them out on the road. Please be
careful clipping in and unclipping out of your pedals in traffic.
With what other
products will PowerCranks™ work?
PowerCranks™ work with PowerTap, Polar, Ergomo,
Computrainer, Velotron and LeMond RevMaster. Some stationary bikes might be modifiable
if they do have a standard bottom bracket.

improvements become noticeable?

improvements within 2 weeks. For cyclist measurable improvements will take approximately
10-12 weeks.
What is the best
time to start training on PowerCranks™?
Today. Whether you are in between races or ending your
season, PowerCranks™ have a place in your training program. We suggest that
you warm-up and cool down with PowerCranks™ for your cycling and running
during the race season. You can slowly build up your warm-up and cool-down sessions
to 15 to 20 minutes. These precious minutes on PowerCranks™ before and after
your riding / running will greatly accelerate your neuromuscular adaptation. This
will, in turn, allow you to have a solid base at the end of the race season.
How long will
my improvements continue with PowerCranks™?
Anecdotal reports suggest that the improvements will
last beyond 24 months before reaching a plateau.
What should I avoid doing
on PowerCranks™?
When using PowerCranks™ on the road, please avoid
placing your full body weight on the cranks to launch your start from a complete
stop. Since the cranks use a clutch, this type of torque can be excessive and
limit the product's life.
How do PowerCranks™
work?
PowerCranks™ are a patented training device that
integrates a one-way clutch in each crank-arm. Each crank-arm will drive the chain
but not each other. Imagine doing one-legged drills all the time, with each leg
working independently from the other.
Will the additional
weight slow me down?
While PowerCranks™ are heavier than regular cranks,
weight is not typically an issue since they are primarily used for training purposes.
Our athletes have reported that, once they have adapted to PowerCranks™,
the additional weight is not noticeable. If you plan to race on PowerCranks™,
we have developed our XLite models to help you save those precious grams.
