Carmichael Designs also makes an aluminum version of their sealed bearing pulleys. While Titanium is lighter and stronger than steel, aluminum has a lower specific density than Titanium, making it lighter than Titanium by volume. These pulleys are made for riders who want the lightest available, while the Titanium pair is the most durable pulley that's made of an exotic, light weight material. This set is machined from 6061-T6511 aluminum in the same shape as the Titanium pair, and uses the same bearing as the Ti model. They have a pair weight of 23 grams and will replace any known rear derailleur pulley that uses the standard 3/32" x 1/2" multi-speed drive chain. The aluminum set has an anodized finish available in Blue, Black, Green, Lavender, Red, and Silver.
