## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    pretty good
  

*by E***N on Reviewed in the United States on 28 May 2023*

My reference point to this is from a 2 pot deore front brake. It took a while to break in the pads, and after a few rides I think i get about 30% ish more stopping power than the 2 pot deore's. It does have better modulation and so far I have not found a hill where this brake struggles to maintain control and the ability to stop.

### ⭐⭐⭐⭐⭐ 







  
  
    Braking power, fade free, and good modulation
  

*by J***E on Reviewed in the United States on 8 August 2022*

These feel different from the XT 4-pistons on my other bike in that the lever travels more and doesn't become hard so quickly.  That travel gives you a good feel of the brakes.  When you want to lock the wheel just pull harder and under any condition they will stop.  I have not felt any fade.
