Just realized the irony of disc brakes on an aero bike.
I rarely have these genius moments but this is for sure one of them. The whole purpose of an aero bike is to use them on flat stages where constant speed is high enough that the aero advantage of aero tubes offsets the weight penalty, and the purpose of disc brakes are to avoid overheating of carbon brake tracks on mountain stages where lots of braking take take place. If an aero bike is not used on mountain stage, then caliper brakes would offer better aero gain than disc brake, as well as reducing overall weight close to 6.8kg as aero bikes rarely make to that light. But since everything in the bike industry is about marketing and forced gear retirement, the manufactures probably don't want you to know this. One can argue that discs offer better braking in wet weather, but with recent year pads and brake track improvement I highly doubt discs even offer that much better braking performance.

Your underlying assumptions are incorrect. Even aero bikes have no problem hitting the UCI minimum. Well engineered aero frames with flatmount disc brakes have better aerodynamics than caliper brakes, depending on who you believe.

And better braking is better braking, applies to flat roads, wet weather, and downhills.

just take a giant bong rip, turn on a hairdryer, and exhale while kneeling in front of bike with hair dryer pointing to rear of bike to see the aerodynamic drag.
then calculate the coefficient of friction as the square root of the thc content multiplied by the v02 max of the rider divided by the gear inches of the top gear configuration. |

There was a minor faux pas from Mavic support during the tour last year. Dan Martin recieved a double wheel change at the start of a descent, he's running discs. after 10km of descending the team car comes up and does a bike change. Mainly because things were a bit iffy on the descent and he was running 160 rotors but Mavic gave him 140's

landis should lead the research effort.
maybe even come up with cbd chain oil. |

BTW, I worked on a tri bike for Drew Scott that had these really awful, integrated into the fork legs and underneath chain stays, blade type brakes that were, VERY aero. Had to be more aero than any caliper/rotor setup...only problem, they didnāt farming work!!!

I do like that this is not turning out to a disc sucks thread. Well done everyone |
