Each bike is equipped with two pedals, one for each leg, which represent two of the 5 points of contact between the rider and the medium (the other three are: two to the handlebars and saddle).
The pedal is a small base which allows the thrust (and tension) lower limbs on cranks; ruled by the latter, it settles on the opposite side to the advertisement of the pin of the bottom bracket, taking full advantage of the natural lever of pedaling.
The pedals are made of a plank that is screwed onto the crank and a ball bearing system (or pads) that allows the rotation of the pedal body. This structure allows the pedal to be well anchored to the crank while turning nimbly onto itself.
In cycling blog, the pedals have a pivotal role; in fact, their surface helps to maintain a correct position of the plantar fascia, which is essential to the efficiency of pedaling biomechanics.
An incorrect prediction of the measures, due to the wrong pedal and then adjusting the bike (frame, cranks, foot position on pedals, forks, adjustable seat post and saddle etc), relentlessly undermines the effectiveness and efficiency of the athletic and can determine muscle and/or resentments should be articulated.
The ride, which is the body that determines the movement propelling the bike, can be of various types: complete, heel and toe:
- The ride of the svettamento heel of the shoe than the pedal which tilts by lowering the back of the foot, thus compromising the action of the calf. It is incorrect and sometimes caused by adjusting the saddle too high.
- The ride includes a unique tip toe full endorsement on the pedal, remaining leaned forward and penalizing even this time the action of the calf. It is incorrect and sometimes caused by adjusting the saddle too low.
- Pedaling efficiency instead, requires that the pedal is perfectly parallel to the ground and that the calf stretches completely. Desirable base is located on the metatarsal, 7-8cm with sufficient precision to predictable before the joint with proximal phalanx of hallux.
The pedals can be of various types and sizes, which differ primarily according to what type of bike (and pedaling), but also for materials, technology and range.
The materials for the axis are always metal, usually steel or titanium.
For the body instead, in bicycles is convenient to focus on plastic polymers (sometimes embedded with platelets reflectors). In contrast, sports bikes have spread light metal materials such as titanium and aluminum; There are also those in carbon fibre and magnesium.
The pedals can be free (flat) or provided with locks to your foot. The latter are indispensable for sporty ride, the one that takes advantage of both the thrust and traction action (for better performance). The flat instead, lend themselves to bicycling disengaged or promenading, and sometimes to mountain biking.
Grips for your foot on the pedal can be of three types: toe-straps, tips and machines to quick release. The toe-straps and the tips are also applicable to the pedals flat; can be leather or leather, plastic or metal. The quick release automatically is a mechanism that, by means of an appropriate interlocking bike shoe, serrano to the body of the pedal; the older ones didn’t leave any backlash for the foot, while those by high range are even adjustable. Also the coupling system may be different from one brand to another.
There are also special pedals fitted with electronic components; is the case of the gauge integrated, synchronized with pedaling its computer (for GPS and navigator).
Pedals prices depend of course from the range and type.
The pedals are definitely cheaper than traditional plastic, for walking or cycling, which costs approximately 4-5 € per couple.
In contrast, the pedals more onerous belong to high ranges that use materials and superior technologies, intended for use in competitions; easily reach the 400 € per couple.
The pedals are integrated with electronic meter out of the norm, since costing up to € 850 per couple.
