currently if got the R-6 wheel and rotor on the bike with the stock caliper and as to be expected with 10mm of extra leverage it has a bit more power but it's minor in my opinion. still waiting on the 320 R-1 rotor and the Old school R-6 caliper. But after waiting so long im starting to lean back over to using on Radial mounted calipers with a more complex but cooler looking payoff like this.
