For those riders who absolutely must have the lightest bike possible, Aerozine have part of the solution. Finely machined and ultra-light, these rear derailleur pulleys add a splash of colour and trim a few grams of weight from your ride. Simple to install, the Aerozine pulleys replace your standard jockey wheels, making spring time an ideal time to get a set after the winter road paste has done its damage. Although the Aerozine pulleys have cartridge bearings rather than the bushings you find in most jockey wheels, I can’t say I felt myself going any faster, but they add no perceptible lag to performance either. If you’re looking for an excuse to upgrade, then, performance isn’t it, but looks and weight are good enough reason. At first glance, the Aerozine pulleys are a luxury but if you need to replace your jockey wheels anyway, then they are perhaps a good choice – just make sure they match your frame colour.
