  • 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.
  • Lightweight, durable and very cheap

    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.
  • 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.
  • Precision product for high performance gear shifting

    posted by puterfixer

    The quality of the product is at the highest levels. The precision of every cut, the low friction of the encapsulated ball bearing, the flawless coating - this little wheel is not only going to change the looks of the bike, but also reduce the energy lost through friction and more accurately position the chain during gear shifts.
    Rear deraillers come with poor pulley wheels, made of solid plastic and with sleeve bearings. They clog up with dirt and the friction is noticeable. Worst of all, their role to guide the chain accurately when shifting gears becomes more and more a hit-and-miss, as the plastic wears off.These replacement wheels bring significant improvements to all issues above, even for high-end deraillers.
    A highly recommended aftermarket upgrade for your bicycle, to improve precision, durability and looks even for race-grade bikes.
