Aerozine Pulleys



The finishing touches to the super-light machine or flashy replacements for the post-winter commuter

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

  • Exceptional
  • Excellent
  • Very Good
  • Good
  • Quite good
  • Average
  • Not so good
  • Poor
  • Bad
  • Appalling

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.

A fun addition to the bike. Hard to justify a purchase on weight grounds unless it is super important to you, but as a stock replacement they seem a good option.
