Shimano 105 Sprocket – CS-5700

Overall Rating:

Do not use the CS-5700 in any combination other than with the 10-speed super narrow chain. Other chains cannot be used as the sizes do not match.

An 11T and a 12T lock ring are available for use with the CS-5700. Use whichever lock ring matches the sprocket configuration.

You should periodically wash the sprockets in a neutral detergent and then lubricate them again. In addition, cleaning the chain with neutral detergent and lubricating it can be a effective way of extending the useful life of the sprockets and the chain.

If the chain keeps coming off the sprockets during use, replace the
sprockets and the chain.

Shimano 105 Chain

Overall Rating:

The Shimano 105 CN-5700 Chain isn’t just any old bicycle drive chain. This ultra-narrow, 10-speed specific chain has chromed link pins and heat-treated rollers, pins, and plates for optimum durability, as well as an asymmetrical profile designed to shift better on the front rings and the cassette. Since the action of climbing up the ramps and pins from one chainring to another is slightly different from climbing up one cog to the next, Shimano chose to shape the left and right side plates differently to optimize the chain for each specific purpose. Shimano also designed the outer plate to reduce the instance of chain suck. The result is a chain that works in harmony with their 10-speed systems to provide a shift quality unrivaled by any of their previous efforts. The Shimano 105 CN-5700 Chain is designed for use with 10-speed drivetrains only.

Shimano 105 Crankset

The 105 crankset has a slim body line & smooth rotation. It provides for optimum balance of light weight & stiffness. Front index is superior shifting performance.

Crank arm length is 170mm
HOLLOWTECH II crankset: Optimum balance of lightweight and rigidity

Shimano 105 front Derailleur

Overall Rating:

The 105 FD-5700 Front Derailleur follows this plan to the letter. Having adopted many of Dura-Ace’s technologies like the wider link design, without adopting Dura-Ace’s price level, we consider this the real bargain of the whole line. Like Dura-Ace, the links have been widened to make the shifter torsionally stiffer. All in all, the shifting will feel smoother, lighter, and more precise. It is different from 7900 in that the cage is wider and designed to work with a front STI shifter that still has an intermediate “trim” shift — Dura-Ace doesn’t have this feature anymore. Shimano says this front derailleur will work with older 6600 shifters, but considers it ‘B’ compatible — it works, but not perfectly. The Shimano 105 FD-5700 Front Derailleur is designed for compact (110mm bolt circle diameter) and standard (130mm bcd) double cranksets. There are three different versions — braze-on, 34. 9mm clamp and 31. 8/28. 6mm clamp (which comes with a shim to reduce the diameter from the larger size to the smaller). It can handle a big/small ring differential of up to 16 teeth.

Shimano 105 rear Derailleur

Overall Rating:

Because the 105 adopts all of Shimano’s best features year after year, the latest 105 components encompass the Dura-Ace and Ultegra technology from just a few years ago. That means the Shimano 105 RD-5701 Rear Derailleur is an exceptional piece of kit build on best of breed product design

Claimed Weight: 221 g
Speeds: 10
Maximum Front Difference: 16 T
Material: aluminum, steel
Recommended Use: road biking

The pivots on the body of the 5701 derailleur are wider than the previous model, and are thus better to resist flexing and twisting when you shift under load. That’s the secret sauce for better, faster shifting.

Shimano 105 Pedals

Overall Rating:

When it comes to pedals Shimano have really changed the game. The SPD – recessed cleat and clipless pedal tech – are now the defacto go-to pedal for serious bike riders

Features include:

Extra-wide stainless-steel platform for efficient power transfer
Low maintenance sealed cartridge axle unit
Quick engagement with the large binding target
Adjustable cleat tension with handy indicators

Make sure your ride is equipped with Shimano 105 pedals or get left behind by the competition.
