The BBB Cycling RollerBoys 10T are replacement derailleur pulleys for older 7-speed to 10-speed drivetrains, aimed at riders who want a tidy, affordable refresh rather than a full derailleur swap. At 22 g for the set and built from Grivory EMS composite with a 40% glass-fibre mix, they’re designed to handle regular road use with better wear resistance than a basic soft-plastic pulley.
In practice, this is the sort of part that makes sense when your old jockey wheels are noisy, hooked, sloppy or just overdue for replacement. The special tooth pattern is there to keep shifting feeling direct, while the complete bushing set gives you more flexibility across older Shimano, SRAM and Campagnolo applications. If you’re maintaining a classic road bike, commuter or older training bike, that broad compatibility is the real draw.
Where these make the most sense is value: you get a sealed, workshop-friendly replacement set without paying premium ceramic-pulley money. They’re a smart pick for riders who want reliable everyday performance and easier sourcing for older drivetrains, but they’re not the choice if you’re chasing the last word in friction reduction or need a pulley for newer 11- or 12-speed systems.
Ideal for anyone servicing an older road, touring or commuter bike with a worn 7- to 10-speed rear derailleur and wanting a practical replacement without overspending.

10-tooth pulley set
Matches older derailleur designs that use a 10T pulley, making it a useful repair option for classic and legacy drivetrains.
Broad 7- to 10-speed coverage
Suited to 7-speed, 8-speed, 9-speed and 10-speed systems, so it covers a wide range of older bikes still ridden every week.
Fits multiple drivetrain brands
Designed for Shimano, SRAM and Campagnolo compatibility, which is handy when you’re keeping mixed-era bikes on the road.
Bushings included
Supplied with a complete set of bushings to help adapt the pulleys to different shifting systems and simplify installation.
Durable composite construction
The EMS Swiss composite with 40% glass fibre is built to resist wear and keep pulley engagement consistent over time.
Special tooth pattern
The pulley tooth profile is shaped to support quick, clean shifting when your derailleur setup is adjusted properly.
Low weight
At 22 g, this is a neat replacement that won’t add unnecessary bulk to a lightweight older build.
