Tangent Trainer

What is the Tangent Trainer

The Tangent Trainer is a patented training device for use on a turbo trainer that bolts between the crank and the pedal. It fits to any bike with a standard pedal thread (9/16), as it uses standard threads and fittings, and is usable with any ‘clip-in’ pedals.

The Tangent Trainer provides an additional degree of freedom between the crank and the pedal. If constant pressure from both feet is not maintained tangential to the rotation of the crank at all times, the link deviates from the correct path and you lose power to the crank. Effectively Tangent Trainer trains the rider to ‘tow’ the pedal cranks around.

What this enables the rider to achieve is to develop a virtually true circular pedalling motion constantly applying force to the crank, clearly the downward stroke is still more powerful as the muscle groups used for this are greater, but it promotes the development of other less used muscle groups into producing power for a fuller circular stroke, and makes the rider conscious of wasted effort on the upstroke due to the trailing foot working against the leading foot.

Trials are ongoing to establish true power gains from a cyclist in real testing but at this stage in the development it is foreseen that increases of up to 20% may be possible when the pedal trainer is used in conjunction with a normal turbo trainer exercise regime.

The pedal trainers are designed purely for use as a training aid and are not intended for use on the road.

Using the Tangent Trainer

When first using the Tangent Trainers, start slowly concentrating on correct technique with a comfortable resistance on the turbo trainer.

As the technique begins to feel more natural, increase the RPM and resistance as required, the intention for these training devices is to use them to develop your pedal stroke to be more efficient and they should be used as part of your regular training regime.

Usage needs will vary between riders, however we recommend using the trainers at least twice a week for 15 to 20 minutes as a minimum, this will encourage the forced muscle memory and technique to become natural.

The technique is not easy to master; you are using muscle groups that are not trained for this and it will take time; some of the trial riders found that starting with one Tangent Trainer attached only (on the non-dominant foot) helped, by mastering the non-dominant foot first, the dominant foot followed more easily.

Others found that taking a video helped, by seeing what their feet were doing during training. Then the points where both Tangent Trainers were not both completely tangential to the cranks became clear and they were able to adjust their stroke and concentrate on the areas where the technique wasn’t developing as it should.

Some users will encounter “the flip”, this is where the Tangent Trainer “flips” over, typically at the top of the crank stroke. This happens because the pedal force is being applied in the wrong direction and at the point where the rider wants to start pushing for the traditional down-stroke, the Tangent Trainer is not leading the crank as it should, and “flips” overOur best advice is to take it slowly and concentrate on both tangents to the cranks. Your technique will develop, and it will be worth it.

Remember, the technique developed is to be carried across into normal Turbo and Road pedalling, don’t stop using your new circular stroke as soon as you take the Tangent Trainers off!
