Disc Brakes 2.0 aka When I Will Buy a Disc Brake TT Bike
Quote | Reply
When I look at current disc brake calipers, it makes no sense that the brake cable leaves the fork/chainstay and then crosses over to the furthest point from the fork/chainstay, out in the wind:

Instead, the cable really should enter the caliper inline or nearly inline with the fork/chainstay. Yes this requires a redesign of both disc calipers as well as disc brake frames/forks, but that gives us an excuse to upgrade to Disc 2.0.

Sure but wouldn't it look cleaner, too? I'm on board. I see no good reason why it should cross over like that

I agree. It could be cleaner. The same applies to the rear caliper.

I guess you have to leave something to improve in the next iteration :)

And if you do route it to the outboard side of the caliper, you'll obscure the bolt that holds the caliper on. Lots of possible issues/heartache there. Not to mention now it might have to protrude further to clear everything. It might end up not looking cleaner or saving any watts and make wrenching that much more of a pain.

If only there were a better way to cleanly integrate a braking system.....

it's hydraulic, should be easy to design it to be cleaner, no effs given about bends, just =make it internal and pop out 1" above caliper entrance( all still internal(plastic arm or whatever), and use 1" of external tubing. hell use this method to hide resevior in fork blade and make damn brake levers smaller.

either way, my rim brake bike is doing just fine hanging on the wall as-is until used again

Well...if that's the integration extent of 2.0, then I guess I'll just wait until 3.0 for the logical next steps of integration ;-)

I look at it this way: until recently, we were quite accustomed to our road bikes featuring cables sprouting from our handlebars. Now, in no small part due to electronic shifting and hydraulic brake cables, it seems almost barbaric (IMHO) to see cables up front. Virtually all high-end bikes are featuring a front end that hides the cables from the wind and the eyes.

I think the current design for road disc brakes was simply carried over from their original application - MTB - many years ago where aero was not a consideration and when aesthetic standards were different.

In 2020 - soon to be 2021 - it seems like an area that can and should be improved. After all, which seems more likely to be the road/TT disc brake standard for future bikes, the photo posted above or the photos below?
