aest rear Customers Reviews

  • Lightweight, durable and very cheap

    posted by jnielive

    They are very cheap, compared to other brands made from the same material, in my country(Denmark)They seem very durable, I've used them for at least 3 months now, and they still look new.The color also seem very durable, it has not been peeling even though I've been biking in some rough terrain, mud and rain.
    I've allready purchased another pair, and have several friends ordering too.
    Buy them, they are very cheap, and as durable as other brands.
  • Super satisfied from the product

    posted by bushavec

    The product is very useful, has a super acceptable price, and it looks like it is super strong.I like it because it is made from aluminum, instead of the stock pulleys on the deraileurs which are made plastic, and are much less durable.
    The fact that it is cnc machined and the color is anodized for the money is unbeliveable, compared to the same products from the bigger brands.
    Why to spend 200% more money on the big brands like shimano and sram for this kind of spare parts, when you can buy them for a lot cheaper and yet be happier because they look so good.
  • Robust lightweight pulley for low budget.

    They really weight 13 gramms only.Perfect for weight-fetishists. In reallity they look much stronger than on the picture, there is material only where is needed.
    I use them on a real racing mountain bike of my son(8years, 25Kg), same as a all other blue AEST parts of DX program.They are low cost, because of best design, this does not mean cheap. But for sure they are worth the money.
    Nothing else found on the market for similar price.Only 13 gramms for both for less than $7.There are some cons, but if correctly used, they are the perfect solution.
  • Very useful!

    It fits both places on my Shimano gear with 5mm shaft and is supplied with an insert for 4-4.5mm shaft. It's light-weight and rolls very nicely. Nice colour, but who looks down there? :-)
    I haven't had these cogs for long, so I don't know how long they last. They roll very easily, but I'm not sure wheather it is roller bearings or not. The old plastic ones wears down fast.
    I'm very positive in the start. Time will show if they are worth it.
  • Pulley for low friction and weight fetishists

    posted by mabiteam

    Really 9 Gramms and a very low friction ceramic bearing and nice too. Works perfect.
    I thought this pulleys would be a must have on a bike of less than 6,5 Kg total weight.
    Again this is one of those products where the Pros are really measurable compared to other products, but produce no significant difference in the whole system bike & biker. It is more the nice to have effect that decides to buy this pulley or to complete the perfection of a top bike.
