How it Works

"Most riders are unaware that some leg fatigue when riding is caused by the naturally occurring uneven resistance of a crank system. The new dual swing arm concept of the Cranktip pedals overcomes this problem whilst also providing greater energy."

Cranktip identified that a significant amount of leg fatigue experienced when riding, is actually generated by the changing pressures or feedback from the crank during rotation, this being due to the inherent nature of how a crank converts human energy into rotating energy.

In practice, whilst the rider generally applies downward forces to the crank pedal, the rider’s foot is constantly being redirected by the circular motion of the crank. This circular motion causes the rider’s leg to experience different or uneven forces during rotation. This is particularly noticeable as the crank arm travels down through the 4 o’clock position. The angle of the crank arm relative to the rider at this position causes it to be less efficient at producing rotating energy and as a result offers significant feedback or uneven resistance that the leg of the rider constantly absorbs. This feedback to the rider’s leg is something that riders have been unaware of in the past and until now, the feel of a crank has simply been what it is. When riding with Cranktip pedals however, the absence of this crank feedback is very noticeable and as a result the rider instantly notices an unmistakably smoother pedaling action not experienced before. We believe that when considering on average, a rider experiences 3500 individual leg actions per hour, it makes sense that the smoother action will greatly benefit the legs of riders particularly over long distances. Whilst the Cranktip pedals smoother action reduces leg fatigue the other major benefit is that the dual swing arm mechanism causes greater leverage or torque during the down stroke. The leverage difference being a whopping 25mm gain at the 4 o’clock position. It achieves this without altering the pedal track circumference or foot speed, this being distinctly different to a longer crank arm for greater torque, that increases circumference and foot speed.

Genuine Performance Gain

As stated, the pedal track of the Cranktip pedal shows an increase in leverage during the down stroke. This leverage increase, or torque, causes a genuine performance gain. The Cranktip pedal when compared to a traditional pedal, is unique in as much that it provides greater leverage and resulting torque ‘without increasing pedal track distance or foot speed’ this being distinctly different to fitting a longer crank to a achieve a greater torque that increases pedal track circumference and foot speed. In a nutshell the cranktip pedal when fitted to a crank arm, provides the leverage of a longer crank, whilst maintaining the pedal track distance and foot speed that would normally be experienced by the same crank arm with a traditional pedal. The real advantage of longer or shorter crank lengths to achieve best performance, is that it allows the rider to choose a crank length that best suits a particular body shape or leg length.

When considering the overall pedal, the Cranktip pedal works on two levels. The smoother action of the crank produces less leg fatigue whilst also providing greater power due to the increased crank arm leverage.

Feedback from riders, including professionals such as Pete Jacobs and Belinda Granger, report that whilst they are achieving better performance times they are also reporting that recovery times are quicker with less leg sting whilst also being able to maintain a more consistent crank rhythm, particularly toward the end of a long race. We believe that the smoother action of the Cranktip pedals will also reduce potential leg injuries. Also those with existing leg injuries including sore knees who are able to ride, are reporting significantly less pain when riding.

How does it work?

The new cranktip pedal incorporates a new dual swing arm concept. (see pedal drawing). The swing arms allow the pedal platform small amounts of lateral movement during rotation so that the pedal platform is not rigidly controlled like that of a traditional pedal. These small amounts of movement of the pedal platform are sufficient enough to dampen and dissipate the varying forces experienced during crank rotation. The cranktip concept employs two combined engineering principles to achieve the very smooth action of the pedals. Whilst the swing arms directly dampen and dissipate irregular forces, they also cause greater leverage. To achieve this, the dual swing arm system effectively repositions the rider’s foot to being 12mm lower and 16mm further forward than that of a traditional pedal. This repositioning of the rider’s foot effectively reorients the pedal track around the crank center. This effectively causes gradually extending leverage during the down stroke (see pedal track drawing). The greater leverage and turning power (torque) effectively softens and more efficiently overcomes the minor increase in crank resistance experienced during the transition into the less efficient 4 o’clock position. This benefit, when combined with the dampening effect of the dual swing arms, provides a noticeably smoother pedaling action with increased torque.



Biomechanical Advantage

From a bio-mechanical point of view, the gradually extending Cranktip pedal track, reaches maximum extension from the crank center during the 3 o'clock to the 5 o'clock position. This best take advantage of the rider's leg as it straightens. In other words the effective crank arm length is at its' longest position from the crank center, providing the most turning leverage, when the leg is at its' strongest. In practice and to further understand this, when the leg is most bent in the vertical up position of the crank, the leg muscle works particularly hard with significant movement to create downward forces and also this is where significant calorie burn is experienced. As the leg straightens however, during the down stroke, it naturally becomes stronger with less calorie burn and as a result of this, the bio-mechanical difference between traditional pedals and Cranktip pedals, occurs mainly between the 3 - 5 o'clock position of rotation. As a result, this is highlighted by the fact that the leverage difference between the two pedals shows the pedal track of the traditional pedal as being 25mm closer to the crank center at the 4-5 o'clock position and accordingly not taking advantage of the straightening leg as well as the Cranktip pedal. This leverage difference is very noticeable and highlighted by the fact that when riding with Cranktip pedals they are noticeably easier to push down. To further confirm that a real biomechanical difference occurs, heart rate is generally lower when riding with Cranktip pedals, everybody tested so far experiences a 5 to 10 beat heart reduction when riding with Cranktp pedals.


Cranktip pedals have been approved to ride in triathlons in most parts of the world. For road racing Cranktip pedals are subject to UCI approval. We suggest to check with your particular club before purchasing. For those with leg or knee problems we recommend training with the smoother action of the Cranktip pedals, this is particularly relevant when considering that actual racing time represents a very small percentage when compared to training.

Value for Money

When considering value for money, we don’t believe that there is any product on the market today that you can instantly notice a performance gain in the same way as a Cranktip pedals. The beauty of this new product is that you don’t have to rely on, or be convinced by scientific testing to prove the performance of this product. You can easily test this yourself in half an hour or less. Everybody has a best time over a given distance, whether it is over 15 minutes or an hour or more. In the case of Cranktip pedals however, even when riding Cranktips for the first time over your best time ever distance, we know you will be shocked at the time improvement. Everybody that we are aware of that has conducted this test, has always had a performance gain. Furthermore you will also be surprised at the smoothness these pedals offer. Until you ride Cranktip pedals however, this extra benefit will be difficult to understand.
