Brake calipers/rotors

[KMF]

It has been brought to my atention that the Radicals use Hi Spec Motorsport calipers and rotors. I have also read that there has been quality isues with Hi Spec components from an other fouum. Has any Radical owners had or heard of such problems with these or with the dealings with Hi Spec

No problems what so ever, ever.

Thanks for that, i am thinking of putting a set on my Atom, the R114-4 calipers. What size pistons do they use on the Radical calipers
