Superbike vs Gravity bike

A challenge last monday Aug 15th (result unknown, may be the ****
crashed himself) between a GSX750R and a bicycle prepared for
descending roads. The road is the most extreme road in Spain, with an
average fall of 13% and peaks of 24%.

 

And linked from the index page:

There's some ... ummm ... interesting machinery there.

I can see that the result would be close.

I prefer uphill twisties to downhills, myself.

I prefer a bar with beers amid the twisties, myself and

Cool. But why don't they picture Diego Herrero and his /actual/ Gixxer
rather than young Mr.J.Hopkins and his MotoGP bike...?

 

With you there, bro.

No worries. I'm sure he looks the part.

 

Ah. I'm sure madriders.com are chuffed to bits.

Erk.

Made me think, though - you know those downhill races they have for
mountain bikes? What's to stop someone taking an engine-less MX bike,
or similar, and entering that? Surely its better chassis would piss all
over the pedal-driven things? Or do these races have some sections
which are flat or uphill so you actually have to pedal?

You've clearly never looked closely at a downhill bike's chassis.
Oddly enough, you're not the first person to think like this.

There are lots of bits that need pedalling - even on steep, straight
downhill sections where you might be getting, say, 30mph from gravity
alone, pedalling will be able to push that up to 50 or so.

A mate at primary school (David Burke[1][2]) did that some 30 years ago
with an old MX bike, except he went one step further & added pedals
too. It was far & away the coolest pushbike on the block, & quite
possibly the only pushbike around with suspension & drum brakes.

Well, see Ace's post, but pukka downhill mountain bikes are
effectively *very* lightweight motocrossers now anyway - lighter cos
the don't need to support an engine, and only deal with 1 bpp [1]

I love UKRM acronyms )

I remember some test of a downhill bike against a engine-less MX bike.
Still, the lighter frame of the bike helped. If the path to follow had
all been high speed, a stiffer frame would have won.

 

Yes, you're right, I've never looked. Thanks (and to Champ) for the
heads-up. Mind you, 50mph downhill on a bloody off-road push-bike.
Jeez. What sort of protective gear do these guys wear? Sounds bleedin'
lethal to me.

Well, that's the fun!

The riders wear full face helmets and moto-cross style body armour -
the only real difference is they don't wear huge FOAD mx style boots,
so they're about as protected as MX-ers. Apart from the fact than MX
races aren't run through the trees...

Only 50mph?

Fastest Cyclist On Snow
The fastest speed attained bicycling down a glacier is 212.139 km/h
(132 mph), by the downhill mountain bike racer, Christian Taillefer of
France. This was achieved on a Peugeot cycle at the Speed Ski Slope in
Vars, France, in March, 1998. The snow cycler's position is optimized
by aerodynamic pedals; the rider is dressed in an airproof Lycra suit;
fins are attached behind the arms and legs; and a large, streamlined
helmet is worn.

Obviously, off-road downhill cyclers do not use Lycra

You do have to pedal, racers will pedal like mad even on the steepest
downhill sections. Most downhill mountain bikes are not too far
removed from an enginingless motocross bike now anyway. Substantially
lighter though (40lbs normally).
