These are Shimano’s third category of pedal sets and they do feature much of the same characteristics found in the other two groupsets. With so many similarities, how can we tell the difference?
To get a great replacement pedal set, you need to consider the weight, material build, and special features that a set provides.
Last month I received my Shimano 105 R5800 pedals and I couldn’t wait to try them on. What I immediately realized about them was that they were very slightly lighter than the R5700 models that I had earlier.
I loved that their platform was wider and that they were fitted much closer to the axle. Also, the fact that they were made of carbon sufficed in lowering their overall weight.
By sight, the R5700 and R5800 look very much the same but if you dig deeper you might find some significant differences.
What are the key differences between Shimano 105 Pedals 5700 and 5800?

Shimano 105 Pedals 5700 vs 5800 – How they CompareÂ
Design
Following Shimano’s tradition to pick from features of previous models to create new models with some similar properties, these Shimano 105 are SPD-SL pedals that have some of its features matching with previous Ultegra and Dura-Ace models.
The two 105 models are made of significantly lighter carbon material. They also offer a wide platform with a replaceable metal cleat plate. This plate covers and shields the cleats from water and grime.
To fit either pedal into the bike, set their tension adjustments, and find their ideal float angle, you will need to use an Allen key. The spring tension on the pedals is also easy to adjust using the 2.5mm Allen key which allows you to turn the screw left or right to loosen or tighten the tension based on your preference.
They offer three degrees of float represented by their yellow-colored cleats with a three-bolt system. If this float is too much you can opt for the two-degree float offered by blue-colored cleats.
Shimano 105 has carbon bodies that provide comfortable and effective pedaling with easy clipping in and out. A metal plate covers the center which helps reduce damage and minimizes the collection of grime and dirt.
Their build is designed to last the test of time. Even if you walk on these pedals, this will not hinder their effectiveness. However, when the colored parts fade, its time for a replacement.Â
FunctionÂ
These being SPD-SL pedals, their engagement mechanism is similar and involves the engagement between the front pedal section and the front of your pedal cleat. The rear is engaged with the help of a sprung clip which holds the cleat by the rear to keep it in place.
The spring is covered which protects it from the effects of the weather but you will have to regularly lubricate the pivot points to keep them effective.
The R5800 pedals use caliper brakes with Cranksets featuring the four-arm design with two compact options; 34/50 and 36/52 or a standard option 39/53. This design is best because they all use a bolt circle diameter so if you need to replace it, you simply get a new ring instead of a new set of pedals.
They are available in length between 165 and 175mm which is suitable for all types of riders. Hollowtech technology is applied to keep the weight of the pedals down and to improve their sturdiness.
R5800 offers 11 speeds on three different cassette types; 11-32, 11-28, and 12-25 which promise smoother revolutions with greater efficiency. Shifting gears is done quickly and sharply by the use of the computer designed tooth profiles that do not miss a single shift.
These pedals run on cartridge bearings and you will need an Allen key to screw them onto your cranks.
R5700 pedals offer 10 speeds while R5800 pedals feature 11 speeds with caliper brakes and quick gear shifting.Â
Shimano 105 Pedals 5700 vs 5800 – A Comparison OverviewÂ
Shimano R5700 – Overview
[amazon box=”B003UA5X9A” template=”horizontal” ]These pedals are available in either silver or black and are built to work with 10-speed groupsets. They are made of alloy and have a stainless-steel plate covering that protects the cleats. The axle rests in a sealed cartridge which minimizes the need for maintenance.
Pedals have a broad platform that encourages better connections between the foot and pedal providing for greater and more standard power transfer along the axle. This platform is highly responsive and moves quietly.
Clipping in or out of the pedals is made easy because the pedals are weighty. With the open structure of the pedals, the cleats are effectively easy to adjust and there are no problems associated with loose footing.
These pedals are available in the three degrees of float yellow-colored cleats. However, if you prefer a much tighter fit, you could pick on the blue cleats or the red ones with zero float angles.
ProsÂ
- Strong
- Adjustable float
- Great bearings
- Low maintenance
ConsÂ
- Heavy
105 R5800 Pedals – OverviewÂ
[amazon box=”B01ENSNB8C” template=”horizontal” ]This is a mechanical type of pedal that features three cassette options; 11-32, 11-28, and 12-25. They have an easy shift action with a shorter throw at the lever. The shifting is quick and produces a satisfactory click that confirms ever gear change.
Calipers on the R5800 have Dual Pivot design that helps equalize the braking forces transferred to each arm and this facilitates better control and greater power output. To manage the modulation of the calipers is possible by pushing or pulling on a lever.
These brakes are great for tire sizes up to 28mm. Cranksets feature the four-arm design with two compact options; 34/50 and 36/52 or a standard option 39/53. This design is best because they all use a bolt circle diameter so if you need to replace it, you simply get a new ring instead of a new set of pedals.
They are available in length between 165 and 175mm which is suitable for all types of riders. Hollowtech technology is applied to keep the weight of the pedals down and to improve their sturdiness.
R5800 offers 11 speeds on three different cassette types; 11-32, 11-28, and 12-25 which promise smoother revolutions with greater efficiency. Shifting gears is done quickly and sharply by the use of the computer designed tooth profiles that do not miss a single shift.
These pedals do not have spanner flats and so use an Allen key for screwing them in. They use the same SPD-SL clears with a degree of tension adjustment on entry and release.
Pros
- Durable
- Affordable
- Multiple float options
- Good bearings
- Adjustable tension
ConsÂ
- Heavy
So, which is better, the Shimano R5700 or R5800 Pedals?
Shimano 105 R5800Â is the better choice between these two because they are an upgraded version of the R5700 in their design and functionality. The R5800 offers greater speeds, easier shift adjustments, and their carbon fiber material makes them durable and indestructible.
Just like the R5700, even after long use, the 105 R5800 pedals do not lose their grip and therefore will not present the rattling that is evident in other pedal types.
