Shimano 105 5701 10 Speed Rear Derailleur

Description

The Shimano 105 5701 10 speed 30T is a long cage rear derailleur. Due to this long cage, you can mount a cassette with up to 30 teeth, which is useful for climbing mountains. When riding a triple, you’ll need a long cage derailleur regardless, which makes this Shimano derailleur a perfect fit!
The Wide Link design of this derailleur ensures extra tight and efficient shifting. The large 11-teeth jockey wheels produces less noise and ensure a longer lifespan.

Compability:
• 10-speed Dura Ace, Ultegra, 105.
• 10-speed Tiagra 4600

Note:
This derailleur is not compatible with Tiagra 4700 shifters.
The Tiagra 4700 shifters are Tiagra-series shifters of which the shifter cable runs under the bar tape, while the Tiagra 4600 series’ shifter cable runs over the bar tape.

Assembly

Loosen and tighten the gear cable.
To loosen and tighten the bolt with which the gear cable is attached to the derailleur, you need a 5 mm Allen key. You can find these here.

Removing the chain.
Before you can remove the derailleur, you will also have to remove the chain. How to do this, you can read here. You need a chain tool for that. We have these here. Make sure you buy one of the right brand and the right number of speed.

Use assembly grease for mounting.
If you are going to mount the new rear derailleur, it is best to apply some mounting paste to the threads of the derailleur hanger. You can buy this aseembly grease here.

Assembling jockey wheels.
To mount jockey wheels you need an Allen key of 2.5mm or 3mm. A handy Allen key can be found here:

User tips

Skew derailleur hanger?
A problem that crops up often is a skew derailleur hanger. It can happen if the derailleur knocked into something, for example in the case of a fall on the bike. Luckily it can be fixed! You can read more here.

Clean the jockey wheels well too!
Just like the chain, the jockey wheels on a derailleur get super dirty. As a result the shifting is not as good and it does the lifespan of your derailleur no good. For that reason, it's a good idea to clean the jockey wheels at the same time when you clean and lube your chain. Do this by running a cloth along the jockey wheel while gently turning the chain. Of course it gets to a point where the jockey wheels are worn out. In this blog post you can find out more about when jockey wheels should be replaced and what you'll need.
