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.

Perfectly fine.

The blue colour; it matches my eyes.

Tell us what you particularly disliked about the product

Nothing really, there's not much too it.

Did you enjoy using the product? I am ambivalent really.

Would you consider buying the product? Maybe, if i needed to replace the wheels anyway.

Would you recommend the product to a friend? See above.

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.

got a pair of these on my bike and really like them they look good and last longer than the standard plastic ones that come on your bike. the 11T makes it only compatible with sram and shimano but if you have got campagnolo you need a 10T jockey wheel.

Not bad value at £22 compared to £35 with other manufacturers.

I got a set of the cheapest ones with ceramic bearings on ebay (about £15) and fitted one in the guide pulley (upper) position on my commuter (Ultegra 6600).

The difference it makes to shifting is remarkable. The Ultegra guide pulley is cushioned, giving smooth shifts. These and their like are rigid, so you get much snappier Campag-like shifting. Recommended, if only for that!

These remind me of the blue anodised X-Lite crank caps I put on my old Marin MTB in about 1996. Love a bit of bling!

 1 Likewise. Blue X-lite crank caps, on a Middleburn RS3 chainset with blue spider and middle ring. With blue chainring bolts.
And blue jockey wheels and breakaway bolt, obviously.

Dunno if they'll work with 11.

I have the gold ano ones as this was the only color available here (India) and have used them on Shimano XT though only for races (weight weenie trait).

They shift well.

There is no upper (floating) 'Centron G Pulley' a la Shimano, so the rd adjustments need to be spot on. I found them a bit more noisy than the standard nylon/ plastic pulleys.
Tested the pulleys on some training rides that were bumpy as I thought they might crumple. They've held up just fine.

Yes, I'd recommend them - if one is into functional bling and has a budget for ditto.
