Got Elixr 3’s on mine and they have been hit and miss.
I find I get a lot of noise and vibration through the frame with the standard pads so replaced them with superstar and they seem fine.
Had one caliper burst when I was replacing the pads. I loosened the torx screw on the lever to allow a tiny bit of fluid out and pushed the pistons back ( as told to when I bought the bike ) and it popped the seal in the caliper.
Turns out the lever was faulty so It was sent to Fishers for a warranty and in the meantime, the bike shop lent me a Elixr 3 brake so I was’nt bike less ( which was nice of them )
Thats when the fun started with that “loan” brake. It went straight to the bars on a downhill section and I luckily was’nt bombing it and managed to stop on the front brake.
It seemed to need bleeding because it sometimes worked and sometimes did’nt so I took it back to the shop and they bled it and tried to locate my original brake that had been sent off ( turns out it got lost somewhere so I ended up with a brand new replacment )
That loan brake went again on the first ride and my replacment brake arrived the day after so I took the bike in and told them the loan brake was dodgy and he said ” oh i will chuck it in’t bin “
Not very confidence inspiring, the new brake has been fine so far so I will have to see what happens when I have to change the pads……
