SHIMANO XT M8100 XC vs. SRAM Guide RSC

[Me rida my bicycle]

I am running the new XT 2 pot with 180mm rotors front and rear and very happy with braking power. I am just under 100kg and my bike is light though with fat rubber.

Rotor size makes a huge difference. Even Shimano twin piston brakes stop really well - in fact I'd say they are better than 4 piston SRAM Guides based on my experience. However, I have come to enjoy the base level Guides on my enduro bike for the smooth lever feel and modulation. Codes are stupidly expensive compared to Shimano brakes with the same or better power. For power and an easier and less expensive bleeding experience, get SLX or XT 4 pots. Or Zee of course.
