So, I've known this guy for a few years, first met when I did a short stint of work at a local LBS, he's somewhere between an author and a bike mechanic, he also does some metal work.
He's creating this Book on the ways to prolong your frame life, in the chapters dedicated to the alloy frames (I think 7005 and 6065?)
me and him were debating something he was weighing up adding in his book, it was about
On the rear disc brake mount bosses, does increasing your rotor size by 20mm (i,e 160 rotor to 180) shorten the life of your frame by flexing your seat/chainstay more than it was designed to be?
I argued that it wouldn't do any damage because the rear brake is only as strong as your rear tires traction.
Then he said if you use an adaptor to get that +20mm increase, you cause more leverage on the bolt mounts as the caliper is moved further away from the frame.
He also added that if you have a bike that is designed to operate in areas with less traction (like cyclocross) then your frame isn't designed to take the braking power from using it on the road with say, grippy tires.
What are your thoughts?
