Contributions! 4 Detailed evaluation of mountain bike pedaling

For the MTB, the foot pedal is a very critical accessory. The pedaling power is transmitted from the foot pedal to the wheel. It closely affects your riding efficiency and confidence. If you accidentally miss your footing, it is very likely to bring about the pain of the skin. ". Therefore, the foot maintains personal safety, beautiful pedals can add value for the bicycle, revealing your Mensao's heart in low-key luxury. Selecting a good foot pedal requires some energy to study, but this article will take the mountain bike flat riding as an example to provide some reference for everyone to choose the foot pedal.

 As a senior mountain bike enthusiast, the total mileage per month is more than 600 kilometers. Among them, non-road riding distance is more than 100 kilometers. XC off-road and fast downhill combined with various road conditions are more comprehensive tests for pedaling. Often carrying a car through, difficult to complex terrain in the next round will also bring a lot of abnormal pressure on the pedal. 

4-foot pedals overview:

1: FIRE EYE (Fire Eye) PJ-ARC

Say goodbye to the MG1 on the xc bike and select the first decoy for the full suspension bike– the FIRE EYE (Firehole) PJ-ARC. The foot structure is simple and rough, with 14 nails on each side to achieve excellent grip and 485g weight. 7 kinds of plating color are beautiful and easy to match the color of the bike. In order to match the colors, I actually keep 4 pairs, which is the longest pedal currently used.

2: FIFTY-FIFTY (5050) DH17

FIFTY-FIFTY (5050) DH17 has a good reputation among users as a good footing for exquisite structure. It has been stable in service for two years.

 

3: Crank brothers (Egg Beater) Stamp Large

Crankbrothers launched the size of two optional foot pedal stamping in the foreign country is not small. The price of just a thousand oceans has just hit people's hearts and minds, but the large footing area has always been a temptation to the Big Feet and has been in service for a year.

 

4: Ferei pedal

The opportunity coincided with the end of the year to receive the Ferei’s new pedal test sample, the unique shape, performance is also quite surprising.

 

FIRE EYE PJ-ARC: 

As a hands-on party, first of all, of course, dismembering. The structure will not deceive people, and the characteristics of a pair of pedals have already been determined when the blueprint is finalized.

Robust and sturdy shaft, bottom black is the inside rubber seal

The fire eye adopts the common structure of the inner metal bushing + the outer single bearing. (The new version is changed to the outer double bearing). Because of its weight, it makes it structurally strong and reliable. The inner metal bushing, once it is lubricated with grease, will not feel damp when idle and will give a strange noise when stepped on. The manufacturer chose high-cost Shimano apple butter grease to delay the date of first maintenance to a long time later. The bearings on the outside are common specifications. Although they are easy to damage, they are easily available in the hardware shop and are inexpensive, so they can be replaced periodically as wearing parts.

The pedal's tightness is very bad. The outer side completely relies on the metal screw cover to cover it. Only a weak special rubber ring is placed on the inside of the crank. Once the aging is damaged, the shaft opens wide. Foot pedal body made of aluminum alloy cutting, processing is relatively simple. Purely flat design, thick shaft does not leave room for it. Each of the 14 nails on the tread surface is evenly arranged. The nails can be found in the hardware store at the common specifications. However, there are problems in the practical use in which the nails are broken and cannot be removed and replaced. The first step is to step on the feelings and grasp the leg strength. It is a good idea to take the eyes of the fire as a benchmark for comparison. Except stamp, the footing area of the other three pairs is similar. Fire eye 14 nails distributed evenly, treading leveling, stepping on the padel is very stable and efficient, will not use a small foot when tired people always feel no stepped on the central position of doubt. When riding in the mountains, all kinds of shoes have a good ability to grasp the feet, and it is not easy to slip off when pressure is lifted.

The bright part of the shaft can be seen that the pedal adopts the inner and outer double sleeve structure, the inside is large and the outside is small, and the top slender part is fixed to the plane bearing

The Fifty-Fifty pedal structure is meticulously crafted and truly domestically produced. Inside and outside the two German nylon sleeve, the outer side of the flat bearing, both ends of the inner and outer seals have multiple rings to prevent dust and water droplets. The original package also comes with a complete set of seals for replacement, very considerate.

The tread body of the aluminum alloy cutting is more delicate, and it has obvious concave shape with high middle and low sides and achieves a better fit with the sole of the foot. 13 nails per side. The nail is a special specification with a thin top and a thick bottom to prevent the top from being unwound from the screw after the impact has been twisted.

The intuitive contrast feeling of FIFTY-FIFTY DH17 is that there is obvious depression in the middle of the pedal, but the gripping force is stronger and more stable. It's easier to take the rear wheel when flying and doing the action. It's not easy to shake the rocky hillside and give people enough confidence. This pair of pedals compares the soles of the soles. It is easy for the cushioning absorbing cross-country running soles to be pierced by a hole or even to open a deep groove. Another way to ride a bicycle and hike it is to consider shoes.  

 

Crankbrothers (Beating Device) Stamp Large:

Screw holes on the outside for oil injection and exhaust

The eggbeater stamp uses a medial twin bush + outer bushing design that is very creative. The inner two-way tile is embedded in the rotating shaft to lock the inner and outer movable clearance of the pedal, and the outer shaft sleeve achieves a considerable inner diameter and length in the thickness of the pedal body, so that the contact portion at the top of the rotating shaft is thick and long, which ensures reliability. The main part is different from the other three bright and beautiful electroplating appearances. It adopts a gravel type rough surface to express its own high-strength positioning. Therefore, it would be logical to use it without a seal rubber ring on the inside. Only red and black colors are available, and the lack of expression is often the main reason for being ridiculed. There are very few depressions on the tread and there are less than 10 chicken/milliscrew screws on each side. However, the Large is significantly better than other foot pedals.

The Crankbrothers pedal's large flat step gives people peace of mind when stepping on it. It's really even better if it's actually used. It gives a strong sense of stability when riding and it's like giving back Stepping on the concrete floor, the psychological feeling is very strange. Although the area of large nails scattered, but the performance on the hill is very colorful, full grasping the foot. Unlike the Fifty-Fifty, it is so obvious that you can feel feet embedded in the lines of the soles, but the bottom of the feet is a very firm combination. It is like sticking double-sided tape, which fully shows that the scientific and rational design can have a tremendous effect.

After tossing over the above couple of pedals, we can easily understand the design idea when we dismantle the last-to-hand flying foot pedal. Adopt the inner nylon sleeve + outer bearing structure, simple and reliable, all can be repaired and replaced; the shaft length is equal to Fifty-Fifty, the top through-bearing part is the same as the fire eye, and the balance between weight and strength; the tread surface has a certain concave, fitting Feet; 11 machine screws, increase the strength to avoid impact deformation and break. The outer screw cap and the inner side are provided with 3 sealing rings, which are the most isolated from dust and water droplets. Through the finishing of aluminum alloys, the visual effect and weight are further increased. It can be seen that although its design is not as sophisticated as the Fifty-Fifty, it is also a well-considered masterpiece.

As a latecomer, Ferei pedal has better design and absorbs the advantages of the previous products. The relative shaft front and back edges maintain a certain degree of concave and each side is distributed with 11 machine screws. When wearing shoes at the bottom, you can feel the amount of depression in the middle of the pedal. You can step on the pedal and feel comfortable. When you do the movement, you can use your feet to ensure that you have a reliable pedal. And it is full of affinity for all kinds of soles, even if it is the pursuit of barefoot feel five-finger sole thickness of only 3mm can also fit well to play, cycling to the playground cannot be replaced with another pair of shoes.

 

The first thing I talked about was that my friend could not talk about running, but according to my experience, as long as there is a pedal that is maintained in time, there is no friction resistance when it is stepped on, and it is very smooth. As far as the four pedals above are concerned, the use of fire bushes with metal bushings will result in a poor condition once the bushing portion lacks grease; the nylon bushing itself has a good self-lubricating effect and a certain degree of elasticity; Should pay more attention to maintenance on a regular basis, so too forced to replace the nylon bush too much toss.

During maintenance, we obviously applied a lot of grease to the shaft, but due to poor fluidity, the bushing part will still lack grease lubrication after some time. Here are a few tricks that apply to fire eyes and flying sharps that have outside screw caps:

1: Put the bike down and unscrew the outside screw cap

2: Add a small amount of high viscosity lubricant, such as the green cover finish line

3: Replace the lid, rotate the pedals, and wipe off the inside of the pedals after seeping oil. The principle is to use the good airtightness of the foot pedal to press oil and grease down and lubricate the sleeve

 

The seal design of the shaft part is good, and the maintenance cycle can be relatively longer. Poorly sealable feet in addition to maintenance of the diligent point, muddy water to play after the best have to check, riding a car directly lost after the romantic dip in the river to go home if it is still lazy, when the shaft makes a whining sound only It can be replaced.

The inner side of the pedal is too large in the middle of the bearing and can be coated with glue.

 

Playing cool and bumping downhill is inevitable. Even if a person falls on their backs, most of the time we still hope that the parts in the car will continue to be at ease with us for the next ride. After three or more intense collisions, the three pedals turn without any, and the Fifty-Fifty has a significant increase in friction. After the oil is maintained and adjusted, the outer screw is loose and cannot be completely resolved. It is estimated that the top of the shaft may be too fine. The new pedal has improved the flat bearing locking structure on the outermost side of the shaft, and there is time to try again.

To avoid misleading, I do not use a simple scoring mechanism in comparison, what kind of pedal is what you want, I believe we will naturally have some experience after reading this article. Some of the color design, such as the concave plane structure, thicker machine screws, perfect sealing, large stamping plane, etc., won me a lot. The Fifty-Fifty and the first foot pedal launched by Ferei’s two mainland brands are all so mature and undoubtedly more promising in the future.
