## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    You need to have lose bearings in your wheels. Example; Shimano cup and cone loose bearings.
  

*by G***A on Reviewed in the United States on July 15, 2018*

Excellent low friction ball bearings, Used these on aeromax wheels. Went from 12 miles an hour to over 20 on flats, on hills from 6 miles per hour to 11 miles per hour. The bike rolls a lot smoother and I can ride longer. Instead of buying new wheels, I will switch all my wheels to ceramic bearings.I recommend these to everyone that wants less friction and being able to gain more watts.

### ⭐⭐⭐⭐⭐ 







  
  
    Decent upgrade for the pricepoint.
  

*by T***Y on Reviewed in the United States on August 23, 2015*

Replaced older steel bearings with these.  I used moly grease to lube.  After a 20 mile test ride, I can feel a difference on the roll-out distance from downhill coast.  Time will tell if these are worth the cost.  I will update after racking up a few hundred miles.
