LOL! that was meant to be a drool icon.....

 

BUT, these guys are loosing the essence of a road bike - disc brakes are for MTB's

That must be heavier than my little titanium calipers?

Yip,

 

Technology is entering the roadie's world more and more.

 

Electronic gruppos, hydraulic brakes, power metres, etc

The carbon wheel riders must be happy to see this development. Arch calipers play havoc with the carbon brake surfaces, especially on the clinchers. And wet weather braking on a set of carbon hoops...........disconcerting.

 

But the set-up looks heavy. A close up of the brake levers will also be good. I would like to see how it is done.

I can see PRO teams fitting their disc brakes on wet weather days and so on...

I read about this and the wheel guys aren't too excited.

 

The necessary weight reduction to offset the weight of the rotor and calliper is not possible to remove from the rim alone. adverse condition braking performance will be way better though.

 

I would think that 140mm rotors on a road bike would be enough though.

 

They mention mass centralization - as a benefit on wheelset feel and response.

what about aero?

Hey Tarmac,

I don't think it's all about the weight - my opinion is the bikes have bottomed-out at 6 or 7Kg, why bother going lighter? No benefit in my view, in fact the weight does help the ride in various ways like maintaining momentum and stability. I'd venture to say 6 or 7Kg is about perfect.

The discs would bring other more valuable benefits, I would think.

Let's also keep in mind the bicycle reached it's pinnacle in engineering terms somewhere in the 1800's, and has not advanced beyond the basic principle since then. Yes it can be lighter, equipped with electronics etc. but the principles have not evolved.

Just my 10c,

Cheers,

what about aero?

 

Just gel your hair back?

Despite palpable industry excitement, road disc brakes are off the table for 2012, according to the UCI’s technical coordinator, Julien Carron. The UCI’s technical commission will be investigating the technology, and its use on the road, in their sessions this summer.

 

“A request has been sent to the UCI to use them in a [road] event this year, but is has been refused,” Carron said via an email to VeloNews. “The UCI is not necessarily against its use, but we need more time to make the correct decision regarding the safety in competition. I cannot give you a precise timeline, but this will be an important topic of the next equipment commission this summer.

That quote from velonews.com.

 

The concern is the difference in braking of caliper vs disc brake systems can cause risk in the peloton.

 

Interesting stuff.

Oe ja...
