  • Looks cool.

    posted by BigIronOlO

    Looks cool, Its light, tho not much lighter that stock pulley.easy to install, creates a little more custom look.bearings are smooth and quiet.
    Silver would be cool too and other colors. The diameter was slightly larger than i expected but this did not effect function or create any problems.Shipping always takes a while.
    If you would like to further customize you setup it does that and functions too for under $10.
  • rear derailleur alluminum pulleys

    posted by johneco

    Some time ago I noticed that a had a strange noise in my stumpy fsr elite special edition rear derailleur.I checked out the frear wheel center (mavic crossride) and the center was working perfectly.Then i checked out the rearailleur and i noticed that the pulleys were in very bad position.Immediatelly i searched to buy new ones but with sealed bearing and not the craps of shimano.I found these pulleys and they are great. I have already ordered another pair formy giant trance 1 even though the pulleyw are still in good shape.
    We pay a lot of money to shimmano may they have to reconsider their policy for the expensive series to install on them more relyable parts.
    recommended to all of you that you want your bike work and look like perfectly
  • Complete Bike Computer

    Very complete bike computer, it has so many functions-Altimeter-termometer- Max, min km- backlight(This function is very important for night rides)very complete cycle computer
    if you don't need a wireless cycle computer, this is a good choice.i buy this cycle computer because this model have a lot of functions, and is very difficult to find a model with altimer and backlight!
    I advice this cycle computer price and functionallity are good!
  • Great product, great price

    Genuine Shimano product at a great price, plus free shippig. Works perfectly on my Merida bike. My original speed cassette was practically useless after 8 years of almost everyday use, this replaced it perfectly.
    I couldn't install it myself because I laked the necesary tools, but I went to a local bike store and they got it installed in no time and for very little expense.
    For me, living in Argentina, this product was hard to get and very expensive. Buying it from dx saved me a lot of money and trouble.
  • Good deal

    It looks, weights, and comes packed like the original one. Maybe it's a original, Shimano-made product. It's just does work properly. And for a very reasonable price!
    I'm using it with Ritchey Comp cranks fitted with Shimano Sora 3300 chainrings, Shimano Sora 3300 front derailleur, Shimano Ultegra 6500 rear derailleur and SRAM PG-850 12x26 cassete. Feels a little harsh, like it's unlubrificated. But properly i'm using Finish Line Dry on my chain.
    I reccomend if you would like to spend a little or if you have an older drivetrain, but it's better to find correct associations. It's a IG chain, and the HG ones have been around for already a long time.
