BBB RollerBoys jockey wheels in 11 and 13 tooth, a direct replacement pair for worn rear derailleur pulleys, in stock at our Kennington shop.
An 11 and 13 tooth pair of BBB RollerBoys jockey wheels, the small sprockets that sit in your rear derailleur cage and guide the chain through the gears. They are sold as a direct replacement for worn pulleys, restoring smooth shifting and keeping the chain properly tensioned. If gear changes feel sluggish or the chain looks like it is not tracking straight, tired jockey wheels are a common culprit, and leaving them worn puts extra stress on the chain and cassette.
This is straightforward maintenance that most riders need at some point. Check the tooth counts on your current pulleys against the 11 and 13 quoted here before ordering. We have them on the shelf in Kennington for free click and collect, and our mechanics can fit them for you the same day if you would rather not do it yourself.
