Multicolour Bicycle Derailleur Pulley — 11T or 13T

A multicolour-finish bicycle rear-derailleur guide wheel, offered in 11-tooth and 13-tooth options. The supplier describes a 7075 aluminium-alloy pulley body.

Choose the tooth count

The 11T and 13T photographs have their tooth counts printed on the centre covers. The supplier diagram shows approximately 41 mm across the 11T wheel and 50 mm across the 13T wheel. These are alternative options, not a two-wheel set.

The electroplated multicolour finish may vary in colour placement from the reference photograph.

Check the complete pulley fit

Match your original tooth count, pulley position, mounting bolt, spacer arrangement and derailleur-cage clearance before ordering. The supplier mentions 4/5/6 mm mounting arrangements, but a complete compatibility list and confirmed spacer contents are not supplied. Universal derailleur compatibility is not established.

The source does not establish a ceramic-bearing option for this listing. No particular bearing grade, friction reduction or shifting-performance improvement is guaranteed. Follow your derailleur manufacturer's installation instructions.
