2) You need a 200mm rotor, 203/205 will be too big for the SRAM caliper.
I went with Shimano Ice-Tech rotors as I think they make a slight difference to the brake feel, being more consistent over a long decent as they don’t heat up. They are expensive though and have a more finite life. That meant using +20 addapters and some shims to lift the calliper the last 1.5mm to clear a 203 Shimano rotor.
In general, most rotors are much of a muchness. Some are noisy, some cause pulsing, some just don’t seem to grip the pads. I tried the superlight ones that are more air than rotor and eventually decided they were pointless. The best rotors are the ones with the most surface area. The more solid the brake track the better they work and presumably the more heat they can reject to the air. That’s why I prefer Shimano rotors over SRAM and others.
When I look at the spec for Scandal they have a 203 mm disc listed as an option.
SCANDAL
This contradicts what you say then.
Or do you have a Scandal also? And can confirm 203 mm disc wont work without shims?
Its getting confusing this
