That would be too much of a difference. It will at least loosen the quick release so the wheel falls off, but in more extreme cases, it can snap the brake caliper off due to twisting forces of the large rotor.so I am running a 203mm disc and shimano slx hyd brakes. I was looking at a Suntour XCR
LO-R-29-AIR it says 185 max disc. How bad would that be? lol
Well two obvious bads would be 1) brake torque rips the caliper off the fork (lowers are made of soft alloy) jamming the wheel and sending you over the bars onto the rocks or 2) brake torque through the caliper buckles the fork lower sending you over the bars onto the rocks. But if you always ride on soft sand or grass, it shouldn't be a problem. Be sure to wear a GoPro so we can lol with you.How bad would that be? lol
Yes, this is true, but it's just a guideline.It's about how much force the fork can take under hard braking conditions.
