For those buying a new machine... disc or rim?

Discuss light weight issues concerning road bikes & parts.

Had a disc road bike and went back to rim for the hassle free non hydraulic solution.
Might go back to disc when they introduce "etap" wireless brakes.

Care to elaborate what model you had (bike/groupset) and what problems you had?
Thanks

Heh... Wireless brakes. What could go wrong?

I think he was joking. Because like you imply... wireless could never fail, so what could go wrong. :)

I can just imagine the threads. "I hit the brakes and nothing happened. Then, all of a sudden, the brakes grabbed hold and flung me off the bike!"

"It did all the queued braking at the same time"

I now have a flat spot on both rims, and my face/elbows.

Or just leave it at “... but nothing happened”. The day manufacturers put wireless brakes on bikes is when I say “Ok folks, wireless simply doesn’t fail, ever”. Because that’s the kind of confidence manufacturers would need for wireless brakes. Until then... shit happens. No one’s going to get hurt if your shifters stop working.
Ha, I just got what @mattr was talking about re the “queued” braking. :)

Maybe it's time for some Alexa/Siri/GoogleHome integration.

Would certainly make the language in the peloton a lot more colourful.

Future can be electro-hydraulic brakes. The wire will go from brake lever up to brake calliper where electro-hydraulic cylinder pushing calliper pistons. Simple, quite safe and lighter. Only braking feel will be gone.

They use brake by wire in F1 and it seems to work pretty well. As said above the brake feel would be much different and would take quite a bit of work to make it feel natural. Still a really cool concept and kinda the best of both worlds, no complex hoses and bleeding but awesome braking.

One thing that brake by wire requires that F1 cars have and bikes don't.
A power source, quite a large one, one that is continually topped up.

Vacuum pumps in conventional cars, hydraulic reservoirs and generators in other applications.

No ones yet come up with a more effective power source than a hand when you are talking about bike brakes.

Erm, I don’t believe there’s brake by wire in F1 (as far as I’m aware) as you’re describing it, all of the brakes are physically connected to the pedal via hydraulic lines as per any other car, the “by wire” bit merely bleeds off braking force to control rear wheel retardation due to the differences caused by hybrid systems/engine braking. I can’t ever see the day when brakes don’t have a physical connection on any bike/motor vehicle.

I thought it was true bbw as the FIA made a ruleling on where hydraulic hoses can and cannot be due to teams having front-rear interconnected suspension via hydraulics. :noidea: Who knows. Cool concept. maybe we'll see it some day maybe we won't.
