On a CX bike it makes sense for one primary reason: moving the braking surface to a clean location. When discs first appeared on MTBs people used to ask me "why?", my answer was usually "because brakes don't work too well in mud and crap".

I think that is a cyclocross bike? Not?

 

The use of disc brakes on road bikes would call for oversized forks and chain/seatstays. It would also render the use of radial spoking useless.

 

I have to ask why.

Because they've reached the saturation point with cantilever brakes, they need to reinvent stuff to make all the old stuff obsolete so they can sell the new stuff and make more money.

As Martin says on cyclo-cross bikes its makes sense because of the mud and mayhem, and its only because the UCI have allowed them to be used now on X bikes.

 

On road bikes what is the point? besides adding additional weight, for which there is no point. You don't need to stop on a tikkie like off road cycling for starters. Hydraulic disk brakes are very good at that, under all conditions.

 

Anyway nice to see some more Hope eye-candy

 

 

(For those who have never heard of a tikkie, it was like a small coin, something like a few cents. A phone box used to be called a tikkie box)

What are you on about? Look again.

You can't use hydrolics with sti unless you use a adapter.

 

aah good point!

 

And even with the regular canti's that CX bikes usually use... how do they rg up the dual lever system?

Here's someone who got a bit McGuyver on his CX bike

I think it has just such an adapter on there. At Eurobike Hope showed a system that accepts an cable entry and converts the exit to hydraulic. This allows you to use hydraulic calipers with a standard cable lever.

TRP make the converter but they are very expensive.

Cannondale SuperX disc prototype – First look

Seem to have gone down the mechanical disk route. Also disks now allow them to build flat seat stays which function as 'micro suspension'.

i dont ever see the point of this on a road bike....it will just add more weight for a stupid reason. We managed well so far with the current brake setups, we also don't go so fast that the current brakes can't stop us...just another money making scheme.

They come in handy on tandems.

Do0d these are cyclo-cross bikes: they need sharp brakes for all those quick stops and dismounts, and there is also lots of mud & mayhem going down generally.

 

And I agree doesn't seem much reason to use on road bikes (besides the techno-bling factor)
