Uh, I don't think so. I'm coming from motorcycles, so very chary of the short wheelbase and high CG of my road bike. I've already gotten the rear wheel *way* up in the air during some hard stops. This is with weight as low and to the rear as I can get it. I have absolutely no doubt that I can endo this thing with no problem - I'm extremely conservative with downhill braking.
