Bike Chains & Drivetrain

Compare bicycle chains and drivetrain components for routine replacement or a change of setup. The number of speeds, chain dimensions and component standard are important starting points.

Match the listed compatibility with your current chainrings, sprockets and shifting system. Check length, tooth counts and joining requirements where relevant. Follow the manufacturer's installation guidance and inspect worn mating components before fitting a replacement.

Multicolour Bicycle Derailleur Pulley — 11T or 13T

Punk Ride · Bicycle Drivetrain Parts

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.

Plastic Bicycle Chainring Guard — Five Models

Plastic Bicycle Chainring Guard — Five Models

Available models

A plastic bicycle chainring cover offered in five supplier model shapes. Choose the model that matches your existing guard and fixing arrangement; each option has its own original supplier-labelled diagram.

G4QA48
G4RB42 1
G4RB44
G4RB48 B
G4XD 48

The model names follow the linked supplier options. They are not a verified promise of chainring tooth-count or bicycle-brand compatibility.

Check the diagram

Compare the complete outline, fixing tabs and the marked reference lines with the guard being replaced. The diagrams label different line measurements for different models; those markings are not presented here as a verified bolt-circle diameter.

The supplier's general written size does not reliably distinguish all five models. A full crankset compatibility list and fitting-hardware specification are not supplied, so confirm the required fit before ordering.

One selected plastic guard is supplied. Crankset, chainring and bicycle are not included; fixing screws are not confirmed as included. Fit according to your component manufacturer's instructions and check clearance from the chain and moving parts.

Bicycle Chainstay Protector — Six Colours

Punk Ride · Bicycle Accessories

Bicycle Chainstay Protector — Six Colours

A flexible protection strip for the chainstay of a compatible bicycle, secured with cable ties. Choose Black, Blue, Green, Red, White or Yellow.

Protection for the chainstay

The supplier describes the protector as soft rubber. Its photographs show one curved strip and two fastening ties for each colour. Check the shape of your frame and leave adequate clearance for the chain, crank, wheel and cables.

Check the fit before ordering

Compare the strip shape and fastening positions with your bicycle. The supplier's size label and length diagram differ slightly; this is an approximate-size accessory, with no bicycle-model fit guarantee.
