  1. K***a

    It seems well-made and indeed lightweight; wear resistance will need to be checked as almost all sprockets are made of aluminum.

  2. AliExpress Shopper

    I made a repeat purchase.
    It’s light, there’s no problem with accuracy, and it’s lightweight.

  3. AliExpress Shopper

    Very well done. Excellent value for money.

  4. AliExpress Shopper

    Very light and beautiful, I will test it to give feedback.

  5. a***r

    Solid workmanship and good switching behavior

  6. AliExpress Shopper

    I’m already using several ZTTO sprockets. Their light weight and shifting performance are excellent. By the way, I’ve been using KMC chains for a long time. As far as mechanical shifting is concerned, I don’t feel the need to use Shimano.

  7. l***i

    item corresponding to the description and received quickly, recommended seller

  8. D***r

    Good, but obviously not that durable.

    I allready bought the secound one an the last about 2000 km with a waxed chain

  9. j***s

    Perfect as described, fast shipping, recommended seller.

  10. K***t

    Top quality item as usual.

  11. D***t

    It is cheaper and lighter than Ultegra but the work culture is incomparable. 🙂

  12. J***n

    Nice

  13. J***y

    Great. Cassette. Light and fast. A++

  14. H***l

    Everything perfect, waiting to try the product and hope its durability is correct or its wear is not too soon.

  15. G***n

    Light and smart

  16. AliExpress Shopper

    Superb, delighted. Best regards.

  17. AliExpress Shopper

    everything perfect, item matches its description, very fast shipping to Spain, very light cassette and works perfectly.

  18. S***o

    Excellent weight. Just over 230 grams. Almost 100 grams lighter than my old Shimano cassette. The gear ratio is very progressive, although the jump from 11 to 13 seems too much to me. I’m used to 11 to 12. But I guess it’s a matter of getting used to it. We’ll see the durability later. Right now, I recommend your purchase 100%.

  19. C***u

    Working well with an eds wheeltop and 48-33 chains.

  20. G***e

    Excellent performance, longevity needs to be tested but being new it is very precise.

  21. AliExpress Shopper

    After my first 100km ride i can without doubt say that this is a great cassette. The shifting is smooth, the quality is very nice and is lighter than my 105. don’t know in terms of durability but for now i consider this a top product

  22. J***C

    Very well.

  23. K***t

    Top quality as always.

  24. A***.

    Better than expected

  25. AliExpress Shopper

    Will want to buy again. Awesome 👍

  26. j***s

    I have several of this type in 11-32, 11-34 and this one in 11-36 and they don’t fit well with Shimano 105 RD5800 and RD7000 rear derailleurs, they work but don’t fit well and for the price they should fit perfectly, a disappointment.

  27. B***e

    Excellent

  28. B***r

    It works very well and is of high quality, better than expected. also very light

  29. I***r

    Weight as described, quality seems good, works well, need to check the durability over time.

  30. D***a

    Excellent quality, this is already the third one of this brand that I order.
    Recommended…..the wear and tear are in accordance with its price which is not bad.

  31. 5***r

    Good

  32. AliExpress Shopper

  37. AliExpress Shopper

    It works perfectly.

  38. s***r

    Very good quality. I will buy again.

  39. J***l

    Lightweight and well made. Fits nicely on hub and changes all smooth.

  40. AliExpress Shopper

    As expected, the ultra-lightweight sprocket had a slight error of only 1g.
    I am planning to go for a test ride tomorrow. The craftsmanship is solid. If any issues arise, I would like to provide an additional review. Since installation was easy, I gave it a 5-star rating.

  41. D***z

    Lightweight and seems of quality

  42. A***e

    Very very nice. Shifts perfectly with a new chain. Those complaint might be using a worn chain.

  43. g***a

    Fast shipping.. Excellent quality.. I recommend it.

  44. B***P

    Ztto ultralight cassette, good quality, great performance

  45. L***i

    Arrived! earlier than expected, well packaged, complete with ring.
    I’ll try it as soon as I have the chance to assemble it.
    Thanks friend

  46. K***s

    I have tested the cassette for a period. It is used on a bike with an ultegra di2 gear system. After fine-tuning the rear derailleur, it works excellently. The cassette is lightweight. I can definitely recommend this.

  47. AliExpress Shopper

    First of all, even compared to the weight of the bike, pedaling feels light and lively, so I am very satisfied with the riding experience and speed.
    It shifts smoothly without noise, highly recommended.
    I haven’t used it for long, so I can’t know about its durability.

  48. AliExpress Shopper

    Amazing quality

  49. F***e

    Chainring package like the original but lighter, fits perfectly without modifications, used in place of an 11/28 Shimano 105 CS 5800.

  50. I***s

    working perfectly

  51. AliExpress Shopper

    Do not buy it at all. After 40km the teeth were torn out and some were bruised. Do not buy

  52. d***l

    Perfect and light

  53. S***i

    Easy and fast delivery, the K7 is amazing. I haven’t assembled it yet, but I’m impressed by the machining.

  54. J***d

    Perfect cassette. Nothing to be envious of an Ultegra while being much lighter. The shifts are smooth. The quality of a Dura Ace for 10% of the price.

  55. AliExpress Shopper

    In the initial order, there was supposed to be an 11.12t high-side sprocket included, but an 11.13t was sent instead, so I returned it. The response was fast, but since it’s a reorder, it took twice as long as usual for it to arrive.
    Well, it was fine since I wasn’t in a hurry, but it’s probably better not to worry about this level.
    The product is light and has a good finish. Compared to some Shimano models, the shifting performance is inferior, but there are no issues.
    Out of the 11 speeds, 1 to 5 are aluminum, and 6 to 11 are iron.
    I haven’t ridden it yet, but I’m curious about its durability.
    However, since it only lasts about a day, I don’t really care.

  56. S***n

    Fast and easy delivery ali express the best i think

  57. AliExpress Shopper

    Goods

  58. C***n

    The cassette is very light and well made. I read another revieve that said a spacer behind the cassette was not necessary and that is correct. I took the space out that was there for the old heavy cassette.

    The shifts on it in the workshop are flawless.

  59. P***r

    Very light, shifting is great with grx

  60. 1***r

    light weight, very nice finish for a low price, now remains to be tested in the field!

  61. k***r

    Works perfectly

  62. A***r

    Top

  63. A***o

    Great product when it comes to cost-benefit ratio!

  64. r***o

    Very good quality, this is the second one I’ve bought.

  65. R***n

    Very nice cassette smooth

  66. c***i

    I have to try it but for the price it’s definitely worth buying.

  67. a***r

    Fast delivery, looks very good. I haven’t been able to test the function yet. The cassette is also very light compared to the original Shimano one.

  68. AliExpress Shopper

    Perfectly fits the Ultegra drivetrain.
    There was some noise during the initial setup, but it was adjusted fine with minor adjustments.
    After testing, there are no shifting issues at all.
    Highly satisfied…

  69. a***y

    Good fast delivery
