  1. F***C

    Great quality. Haven’t used it yet, but looks good on inspection. 192g with lock ring, 187g without. Minor discrepancy but honestly i’m happy

  2. W***i

    The quality is good and the entire piece is a little more than 200g.
    Delivered in a reinforced plastic bag inside of a box.

  3. AliExpress Shopper

    Terrible cassette. Very loose fit on the free hub. Very noisy, gears clicking. Removed it and reinstalled shimano cassette which works flawlessly. Will try to return.

  4. AliExpress Shopper

    perfect and professional paint, weighs 180 grams

  5. AliExpress Shopper

    Package was well wraped and protected.

  6. AliExpress Shopper

    The weight is compliant, all that remains is to test on the road.

  7. AliExpress Shopper

    Very fast shipping and perfectly intact product. It seems to be of good quality, time will confirm whether it is or not!

  8. w***r

    Very good 👍

  9. L***e

    Great cassette for the money good communication

  10. F***i

    Good product!

  11. AliExpress Shopper

    To be clear, all 12 cigs are steel (good) and the separate carrier piece is aluminum (good).
    Looks trick !

  12. n***l

    Super cassette very very light,super well packed and very fast delivery. Can’t wait to try it out. Thanks

  13. p***r

    It’s certainly light, but how about its durability? If there is no discomfort when using it, I’ll consider it good.

  14. AliExpress Shopper

    The cassette is the advertised weight and shifts equally as well as my old ultegra cassette 🙂

  15. M***l

    Meets my expectations weight content (11/34: 194 grams) mounted without play to be seen in use.

  16. AliExpress Shopper

    new ULT 11s 34t

    The weight, including the locking ring, is 184.5g. There is no problem with shifting, but a noise that sounds like metal grinding continues to occur while riding. It’s even worse in the outer chainring.

  17. D***e

    Great product. Only place i could find a black cassette

  18. A***o

    Works great is light after 200km no problems

  19. AliExpress Shopper

    Purchase 12s 11−32
    It was under 200g.
    It is lighter by 50g compared to Dura Ace.
    The shifting performance may not have changed, but the sound during shifting has become louder.

  20. R***s

    Top well finished for the price

  21. k***r

    Works perfectly fine, no difference in shifting quality to my ultegra cassette. the shifting is getting more audible thought. that was to be expected. this is a machined (hollowed out), one piece design to save weight. that process makes them light, yet sturdy. a side effect is though that it got more of a “resonance body” then the solid (and much heavier) shimano sprockets. it’s not worse quality, it’s just simple physics. you can’t have one without the other.

  22. A***m

    Bought one of the new 11-36 versions, ridiculous 161g weight saving compared to 105 and the shifting has been great. I’d buy again in a heartbeat.

  23. B***a

    Not installed yet.

  24. J***e

    It’s light and seems quite sturdy. I’ve only tried installing it briefly, but there seems to be some noise because I didn’t apply oil. I’ll need to assemble it and ride it to know for sure. I’ll leave a review.

  25. W***i

    I’m not sure about the originality.

  26. M***e

    Excellent

  27. B***s

    I’m still unsure about this cassette. Shifting up seems fine, shifting down is very hit and miss. Tried the adjustments through the etube app and no difference. I’ll see what other tuning can be done but currently am not impressed with it

  28. 一***澤

    Lightweight, easy to fit, black.

  29. S***k

    Shifts perfectly with kmc chain. Other similar cassette was not shifting well with shimano chain, yet to test this cassette with shimano chain.

  30. n***l

    Super little cassette works really well on my bike and lighter than anything else on the market.a really fabulous buy.thanks

  31. AliExpress Shopper

    Super cassette works really, well very very light,at an amazing price yhanks

  32. a***r

    This cassette is perfect. 11-34t 11 speed weighs 189g.

  33. f***r

    Very good product, my 2nd one.

  34. n***l

    Super light cassette you would think the parcel was empty.works really well with my existing gear set up.super fas.t postage.and super well packed.thanks

  35. T***i

    I recommend it. It looks very good. It is made in one piece that we mount on the wheel, not like most which need to be assembled from several parts. It weighs much less than a normal cassette.

  36. p***r

    Not working at all, the chain jump continuosly on the small ring. I returned the cassette.

  37. AliExpress Shopper

    Very good

  38. a***r

    Super quick delivery. Item as described. Completely happy with transaction. Would buy from again.

  39. M***o

  40. F***t

    Great product, not fitted to the bike yet but looks a feels quality- very light too.

  41. D***l

    Excellent weight and gears changing. Let us see durability in some time

  42. m***r

    From ordering to arrival, the response was quick and very good. I thought I wouldn’t know about the product until I tried it, but after using it, there are no issues at all. And since it’s very light in weight, I’ll try using it in road races and hill climbs that include uphill sections.
