Rear Derailleur Pulley 11T AL7075 CNC Machined
10 grams of machined AL7075 on a sealed bearing
What It Is and Who It Is For
An 11 tooth rear derailleur pulley CNC machined from AL7075, weighing 10 grams and supplied with one bearing. It is made for Shimano and SRAM 7, 8 and 9 speed derailleurs and is available with a 5 mm or 6 mm bore.
Why Buyers Choose This Part
Machined AL7075 teeth
Holds a tooth profile far longer than a moulded plastic pulley on the same drivetrain.
Runs on a bearing
Supplied with one bearing rather than a plain bushing, which is what keeps it spinning freely once it is dirty.
Two bore sizes
5 mm and 6 mm covers the common Shimano and SRAM derailleur cages in 7, 8 and 9 speed.
Problems It Solves
- Moulded plastic pulleys wear into a hooked tooth profile and make the chain skip
- Bushing pulleys drag once grit gets into them

Compared With the Alternatives
Against the plastic pulley that came on the derailleur this lasts longer and spins more freely, especially once dirty. Against an oversized pulley cage upgrade it is a direct replacement with no cage change.
Customisation and Manufacturing
Machined parts are cut from solid bar on the CNC side of the Shiyan Town plant. Alloy, tolerance and anodised colour are all specified at drawing stage, and the mark is usually lasered rather than printed so it survives handling and solvent.
- Alloy and tolerance built to your drawing
- Laser marking or engraving on the anodised surface
- Anodised colour matched to an approved sample
- Polybag, card or colour box packing
Fitting and Living With It
Step 1
Check your existing pulley bolt diameter before ordering, 5 mm or 6 mm.
Step 2
Note which way round the old pulley came out. Guide and tension pulleys are not always interchangeable.
Step 3
Clean the cage plates while the pulley is out.
Step 4
Check the chain runs centred on the new pulley before riding.
