According to BBB website BDP-02.BK RollerBoys 11T jockey wheels are designed to work with most modern Shimano, SRAM, and Campagnolo rear derailleurs across 9–11 (and in some listings 12) speed drivetrains.

Supported drivetrains

From BBB’s own specs, these 11‑tooth pulleys are listed as compatible with:

• Shimano 9, 10 and 11‑speed systems, including “Mega Range” 
• SRAM X0, X9, X7 mountain derailleurs and SRAM Apex, Rival, Force and Red road groups (post‑2011)
• Campagnolo 11‑speed derailleurs

BBB’s global product page describes them as high‑end pulleys for 9, 10 and 11‑speed, compatible with Shimano, SRAM and Campagnolo, and supplied with a complete set of bushings/washers to match different derailleur designs.

Practical takeaway

If you’re using a mainstream Shimano 9–11 speed road or MTB derailleur, a SRAM X‑series MTB or Apex/Rival/Force/Red road derailleur (2011 or newer), or a Campagnolo 11‑speed setup, these RollerBoys 11T should be a direct fit when installed with the correct bushings supplied in the kit.

Worldwide Reviews Collated & Summarised

Overall sentiment

Across UK, European and global retailers, the RollerBoys 11T typically sit around 4.5–5.0 out of 5 stars, based on dozens of customer ratings. Users often describe them as “good product,” “great value,” and “thoroughly recommended,” with multiple reviewers saying they would buy them again as their default replacement jockey wheels.

Key positives riders mention

• Smoother, quieter shifting: Many reviewers report an immediate improvement in gear changes and reduced drivetrain noise after fitting these pulleys, sometimes noting they now hear only tyre noise instead of the derailleur.
• Better than OEM parts: Several comments explicitly say they are better than mid‑range Shimano or SRAM originals, with smoother bearings and comparable or longer life, while costing about the same or less.
• Easy to fit and versatile: Users like that the kit includes different bushings/spacers, making installation on various derailleurs straightforward, and mention fitting them to SLX, Ultegra, 105, X7, and other mechs without problems
• Good value for money: Reviews emphasise the combination of price, build quality and performance, often calling them a “cheaper alternative to the big S” (Shimano) or a “great value, good quality” upgrade.

Criticisms or watch‑outs

• Longevity still observed over time: A few reviewers note that they will judge full durability only after extended use, but early impressions of materials and grease packing are positive.[
• Basic composite look: Some users mention that they are light plastic/composite rather than fancy anodised metal, but generally see this as acceptable given performance and price.
