  1. AliExpress Shopper

    Very good

  2. K***n

    Comes with two spacers for mtb and road. Machining quality is good, we will see about the bearings. The inner diameter of the bearings is 30mm and it hase a plastic sleeve to reduce it to 29 mm.

  3. AliExpress Shopper

    My attitude to these bottom brackets is to replace the bearings when they were out but if you’re looking for something to fit and forget then chris king is the answer

  4. B***o

    T47 bottom bracket, external 30mm. Quality of the unit is ok for the price, however the bearing quality is not so good, they only lasted around 500km in dry conditions. I will replace the bearings with higher quality ones
