Cyclist vs Porsche

Great point Perfectlap. Also, the almost exclusive use of carbon fiber rims adds to the reduced braking performance from rim style brakes. Interestingly, the use of disc brakes in both cross and mountain bike races has proven the technology to be effective. One of the main limiters is that they are too effective and modulation becomes an issue on the road. Back to Boxsters....my car stops incredibly fast.

yes disc brakes are superb for offroad. No contest the stopping power simply does not compare. So many face first crashes into logs and trees could have been prevented with these 20 years ago. But what a hassle to keep them quiet. They require more cleaning than my Boxster! I have disc brakes on my 29er and single speed cyclocross bike which I ride during winter as commuter bike with studed tires. I have to keep a bottle of rubbing alcohol right there on the bike stand to clean off the brake pads after each ride.
