bike derailleur Customers Reviews

  • Looking Nice

    posted by downhillfreak

    Great looking with nice golden-bronze-like colourGood quality. No free play at the axle so it fits well.Aesthetic upgrade for your bike
    Sell them by two against a better price as you need two for a derailleur.I haven't used it long enough yet to comment on the quality of the bearing. It seems okay, but I am curious to see how it holds under muddy conditions.
    It's a simple product and there isn't that much to say about it. If you like the looks of it...buy it. For that price you can't go wrong.

  • 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.
  • 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.
  • Is it noname Shimano???

    Good and precise manufactured. Mounted on LX and Deore, and have noticed that if used as a pair at the same time, the gap (clearances) is to tight, and the chain are not lead well. Instead of pair, should be use only one at the time, the other pulley should live original.
    The shifting are more precise and faster.
    If you use as upper pully, shifting will be more precise, and a little bit faster. Also, the chain fits better over the crank, cause clearances is much smaller then a classic pulley
