  • Good buy

    posted by yskeong

    The cogs have Shimano stamped on it and without having a lab to test it, I will assume that it is a genuine Shimano product. The price of this product is much lower than what I can get in the local bicycle shop in my area.
    The product came with good padding to prevent damage in transit.Apart from the time taken to receive the products, this is a good buy.
    It is a Shimano product. Can buy without apprehension.Shimano CS-HG41 Acera 8 Speeds (11 - 32 T) cassette on my MTB has been giving me trouble free ride for thousands of KM already.I am buying this new unit to installed on my new set of wheels.
  • 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!
  • Original product at a great price

    Original Shimano product at a great price, Works 10 points on mi Merida 24 speed bike
    My other chain was very worn out after 8 years of almost everyday use, so I had to replace it and this one fit perfectly. I couldn't install it myself because of lack os tools, but I just sent it to a local bike store and they got it done in no time.
    In Argentina, where I live, this product was really expensive to get. Buying it from DX saved me money and trouble. The only setback was that it took about 4 weeks to arrive, but for the price, it was worth the wait.
  • High quality bearings, good fit

    posted by asdasd123123

    I've bought this little spare piece for my bike a dozen times, never been this good even for ten times the price.Has a ball bearing, no sleeve bearing!
    Works as intended, not quite gold, more yellow.Fit was like a factory new piece, no juddering/skewing.
    If you need this and know what it does, you should get this. There are some other colors, just make sure it's the same model.These are standard size, will not work on the cheaper SIS oversized pulleys.
  • 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.
