BBB’s AM Pulleys and Chain

As derailleur pulleys are an essential bike part for every derailleur bike, BBB puts much effort into creating the best pulleys available. Made of 7075 aluminum to make the pulleys even stiffer for fast shifting, BBB made the Aluboys as they are called, in two versions.

The BDP-21 is the standard version with High-Quality sealed ball bearing, while the BDP-22 has a high-quality sealed ceramic bearing. Both BBB AluBoys are compatible with Shimano 9 and 10-speed and Campagnolo 11-speed.

With the Powerline chains BBB offers a complete range from single speed to 11-speed in a wide range of qualities. The high-end chains are also available in a ‘Self Lubricating’ version. The special coating reduces the need for lubrication. BBB claims that when used on the road in dry weather, the PowerLine Self Lubricating chains don’t need maintenance for 1,500 kilometres.

For mountain biking the story is a bit different. The lubricating on the chain is released by friction. When the bike is cleaned after a ride the lubrication will also be washed away. Therefore the chain needs to be lubricated manually or by riding again as the friction releases the lubricant from the chain.

The main advantage of a Powerline Self Lubricating chain for mountain biking is that while riding, the chain won’t creak anymore.
