Recreational Cyclocross and Gravelbiking This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like :The Dirty Kanza". We also have a dedicated Racing forum for the Cyclocross Hard Core Racers.

Must've been one of those one-tooth, perfect clean slice chain rings.

The cut's on the left side of his left calf. It happened during a traffic jam on a flyover when everyone was forced to push/carry their bikes.

Yeah, well, no conspiracy theory here. After all, I shot Kennedy myself. I was underneath the car the whole time.

Funny that Trebon felt the need to clarify exactly what instrument resulted in his injury on twitter. Wonder if some 24-year old PR girl had orders to have him to shed light on that, for fear of reducing the panic on the Grassy Knoll.

First, mountain bikers never run and second, we would just ride over the stuff, not try to carry/shoulder our bikes.

The "stuff" in this case being other racers. A fat bike would be perfect for that.

Wow, it's quite a shock to hear that some people embrace a technology and others don't.

Jan Oestergard's race bike had one chain ring and V brakes when most of the top MTB cross country racers were running discs, he still won, lots. Clearly both work but why not use it if it works for you?
Cant believe people seriously think it's a safety concern though.

OK if you want to go all Zapruder, check out around 2:30 on this video:
http://vimeo.com/album/2200561/video/86090023

It's easy to pick out Trebon because he's the tall dude in stars and stripes with the white aero helmet. It's hard to tell PRECISELY when it happened (unless maybe someone has some fancy video app or something) but I don't think any of the possible suspects were even using disc brakes.

Looks like it was that Dutch guy coming up on his left side what did it.

Comedy gold. I've owned a fleet of bikes,worked on over 1K more at my free bike clinic,and have had some spectacular wipeouts playing polo,and not once have I seen an injury caused by a disc rotor. Plenty of injuries caused by chainrings.

If this really was an issue,you only have to look to the world of bike polo for the solution:

For road, it would benefit riders in wet conditions.
We all know how well wet carbon rims perform on decents...
They also save your rims, why replace a rim when you can just replace brake pads, or a caliper.
For cross, save your nice carbon race rims from all the grime/muck/debris that gets caught up/works it way in your brake pads over the course of a race.

Any real data to prove disc brakes give you an advantage in a race... No
Practical... IMO Yes.
Give them time to break them in, they're mfairly new to our discipline, we can get real data over the course if the next few years.
Just like any thing new..."gotta work the bugs out".


I guess I should be replacing my disc brakes for drum brakes on my car right about now...

I'll never use carbon rims for 'cross or probably road either so nope, no disc brake advantage for me. I still don't see the European peloton using them any time soon. But what do I know.

Like I said, once the bugs get worked out...
Companies like SRAM, & Shimano will force riders to use them in the peloton, whether the racers like it or not.
They're some of the major sponsors of quite a few teams, not to mention Shimano teaming up with Giant this year.
They're not dumping millions of $$$, on them just to let them fade into the sunshine.
If Kittel wins a few sprint finishes with discs, they'll be all the rage.
It wasn't long ago that we were all hating on carbon frames... "Assploding"...brittle...plastic...
Now you're like a leprosy survivor if you don't own one.
All in due time... "Haters gonna hate'"

You're probably right, but they have legit purpose on mountain bikes and others, is there anything wrong with sticking with calipers for lightweight road bikes? Horses for courses? Sometimes I think it's possible to over-innovate.

Nope my calipers stop my road bike just fine, I can lock them up quite easily.
According to Shimano, using their disc system has no weight penalties.

I do appreciate having discs on my commuter.

Just looked at your signature. Your ancient steel signature. You lack credibility on the subject of innovation.

The problem is the idea that all road bikes need the same thing. "Horses for courses" extends down to the application, not the bike type. Here in Florida where a "big descent" is the back side of a 60' bridge over the intercoastal, I'd be hard pressed to make a case in favor of disks. But for people in other parts of the world, the trade is going to be weighted much differently. Having choices is good. We just need to make sure that manufacturers continue to hear that we want a choice, not a change.

I have a disc brake on one of my bikes. I just don't think every bike would need or benefit from them. But point taken.

Hit a rock and fell off my bike the other day. Disc rotor cut 6 inches into my neck and I bled out in the snow. True story.

How did you pull this off?
My bike always seems to pull/break away from me when I bail.

^^ Shot off my hub on impact. By the time I knew something was wrong it was imbedded in my throat like a ninja throwing star. Luckily I had some superglue handy!

Must has been riveted on, I can't see a bolt on shoot off like that.
You could have a lawsuit in your hands.
Any pics to document?
