Disc brake Equipped Road bikes

[The Smoovf]

Hi Hubbers.

 

I was just wondering if anybody else is wondering when then disc brake equipped road bikes will be hitting the bike shop floors.

 

I recently sold my road bike and told myself that I would only by a new bike if it came equipped with disc brakes. I understand that it is not going to be from the 1^st of January but would like to get the general consensus from the Hubbers.

 

Attached is a pic of one of the only “mainstream” road bikes that I know of that has been launched. Not sure of availability in SA.

Dont see the discs on that bike

Many cyclocross bikes are being made with discs..

[no calves]

ah now i see them

As far as I know quite a few manufacturers are experimenting with disc brakes and wheel designs in anticipation of a rule change from the UCI allowing disc brakes to be used in sanctioned events. Until this anticipated rule change occurs it is very unlikely that we will see much movement in this regard.

 

Cyclocross has been allowed disc braked for I think just one season so far.

Got the moola?

 

Buy a Colnago disc-equipped road bike!

 

Beautiful!

As should always be asked: Why?

have you ridden a road bike in the wet? ha ha ha

[The Smoovf]

Why as in why put disc brake on a road bike or why do I want to have the hubs' opinions?

1) stopping power (more for commuting and dodging cars, pedestrians and taxis than racing)

 

2) set of rims last very, very, very long

 

3) wet weather stopping power (probably same as point 1)

 

disadvantage = weight

I think on aluminium rims we generally dont have braking issues. But on carbon rims, braking is never as good. I can imagine pro tour riders decending those hectic Alpine passes would apreciate disc brakes on there carbon wheels. Personally, i like the simplicity of rim brakes. I'm often cursing my mtb brakes when they need bleeding!!!

You are right. Disc brakes are a necessary evil for moving over to carbon wheels. On aluminium rims we have no braking problems, not even in the wet now that we know that certain pads improve stopping distances significantly.

You can't go on indefinitely increasing brake force. As it is, we have enough force to overcome the limiting factor - overturning momentum. Discs can't overcome that problem so it cannot be an improvement on that front.

 

In my world rims fatigue at the spoke holes long before they wear through on the brake track.

 

Wet weather stopping has been solved with improved brake pads from Koolstop.

I dont see the need. What next 1.5 inch tyres for better grip?
