PowerCranks


PowerCranks are, simply, independent bicycle cranks that replace the regular cranks found on a typical bicycle or exercise machine. Independent means one leg cannot help the other in making the pedals go around and in order to pedal the bike one cannot simply relax on the back stroke but must actively raise the pedal using your hip flexor and hamstring muscles, generally undertrained muscles in most athletes. This give the rider feedback when he is doing it right (they will work like regular cranks) and feedback when they are doing it wrong (they simply fall apart) and, because they are on a bicycle, the user can get enough duration to train this change for whatever their sport demands, even for hours. This forces the user to learn how to pedal a bicycle in a more efficient and powerful manner and the motion closely resembles a running motion (without the impact). Further, this simple change ensures that your leg muscles will become balanced (both right/left and fore/aft) and that you will be training additional muscles with a coordination important to overall well-being and superior athletic performance whatever your sport. They have been described as plyometrics without the impact or injury risk.

News:

For the fourth Olympics in a row a PowerCranker has won the cycling road race. Bettini X2, Sanchez, and now, Vinokurov.

At the 2013 Ironman World Championships PowerCranker Mirinda Carfrae sets a new run course and overall course record. Just as impressive age-groupers Sam Gyde and Stefanie Adam win their division with amazing bike splits. Sam rides a sub 4:30 bike split, faster than all but 4 pros and then runs a 3 hr marathon to set a new AG record and Stefanie rides a sub 4:50 bike split, faster than all of the pros (she beat them all last year also). Both Sam and Stefanie train on PowerCranks.

At least 25 Ironman Champions won their first Ironman after starting training on PowerCranks.

PowerCranks® guarantees any serious athlete improved performance if he/she depends upon leg speed and power in his/her sport.  PowerCranks® is the first (and only) device available that actually trains the major hip flexor muscles to become aerobic power machines.

Visit the PowerCranks website to find out more about why World Class Athletes like Ryder Hesjedal, Geoff Kabush, Johan Museeuw and many others use PowerCranks.  Find out how you can benefit from these revolutionary training devices.

So, What are PowerCranks™?

PowerCranks™ are a patented new type of training device which establishes a whole new category of training devices.  There has never been anything like them - bicycle cranks that are independent from each other.  We call them training cranks because they help athletes train muscles and improve coordination beyond what was possible before using any other aid or technique.

Ever since the beginning of sport, athletes have been trying to maximize individual performance.  PowerCranks™ solve two training problems important to this end - how to aerobically incorporate the hip flexors into ones sport to improve power and speed while ensuring that both the right and left leg are trained equally.  Now, to do this, all you have to do is ride your bicycle. 

As a cyclist, one way to improve your pedaling stroke to get more power is to "pedal in circles." The problem with ordinary cranks is the rider receives absolutely no feedback when he/she is riding properly or not.  The only way one can insure one is "pedaling in circles" is to receive proper feedback when one is pedaling properly and negative feedback when one is not.  Regular cranks give no feedback either way.  PowerCranks™ is the only device that attaches to your bicycle, to be used during training, that gives your brain positive feedback when you are pedaling properly and negative feedback when you are not.  PowerCranks™ is the first (and only) device that effectively allows you to improve the engine of the bicycle beyond what you can do through simple hard work and previously available training techniques because PowerCranks™ force you to learn proper pedaling technique (circular pedaling) and to aerobically train the muscles you need to use so you can do it for hours. 

As a runner, speed depends on leg turnover rate and stride length.  As the hip flexors become aerobically trained they can be more effectively utilized is all sorts of activities.  In running, by more effectively using the hip flexors to help throw the leg forward, stride length will be lengthened and speed improved.  Now, you can use your bicycle as an effective cross-training tool to improve this ability.  You can run harder without going anaerobic.  Triathletes generally report seeing this improvement start after only 3 weeks or so on the PowerCranks™.

So, to reiterate: For the serious athlete, they do two things that can't be done without them and, for the serious cyclist (and triathlete), three things. 
1.  They represent the first training device that actually allows the athlete to train the hip flexor muscles into serious aerobic muscles.  Turning the major hip flexor muscles (the iliopsoas) allows the athlete to incorporate new muscle mass into his or her aerobic athletic endeavors and recover more quickly from their anaerobic efforts. 
2.  They isolate the legs, preventing a strong leg from compensating the weak leg, forcing the weak leg to obtain the same strength as the strong leg.  A great injury prevention tool and a great rehabilitation tool should you have any physical problems or be recovering from injuries.
3.  For the cyclist, they will also teach your neurologic system to unconsciously "pedal in circles." By pedaling in circles, more of the energy you are now expending actually gets to the wheel! For the same overall effort, the more efficiently you pedal, the faster you go! So the cyclist gets more efficient use of the muscles he/she has already trained and, as noted above, the ability to incorporate new muscle mass into the now unused portions of the pedal stroke. 

Therefore, if you train with PowerCranks™ you will improve your athletic performance, regardless of your sport, as long as you consider leg speed, power, and coordination an important aspect of your sport.  All athletes will be able to invoke more leg muscle mass in athletic performance and cyclists will be able to invoke that increased muscle mass more efficiently.  Regardless of your sport, if you depend on your legs for speed, training with PowerCranks™, WILL make you faster .  .  .  a lot faster – GUARANTEED! 

So, how do they do all of this?

PowerCranks™ force you to use the hip flexor muscles to lift each foot about 14 inches each rotation of the pedal, turning these muscles from couch potato observers of all your athletic endeavors to effective participants.   If you ride at a cadence of 90 this means you must lift each foot this 14 inches 5,400 times an hour.  We don't believe it is possible to effectively train these muscles, to this degree, in any other way.  Also, if your sport involves riding a bicycle, PowerCranks™ also gives you an immediate feedback system as to when you start to pedal improperly – so you can retrain your neurological system to fire your muscles in a different coordination – changing the pedaling dynamic to improve pedaling efficiency.  PowerCranks™ force you to pedal properly.  So, the cyclist gets to invoke more muscle mass and invoke it more efficiently.  Quite simply, training with PowerCranks™ will make you a lot better athlete in any sport that involves leg speed and coordination.

PowerCranks Entry
$699/$799

Entry level cranks are now available for the cost conscious. Entry level cranks come in two different iterations. The first, Entry1 cranks incorporates a standard crank length of 170 mm. and the second, Entry5 cranks, incorporates 5 crank lengths from 90 to 170mm to allow the user to experiment with crank length in large chunks - both while developing better pedaling technique.
