Disc brakes in the peloton

This article reports on the progress made recently concerning disc break safety in road racing. In summary, rotor covers should be available soon.

Shaft drive.  All races to be done on Biketown bikes.

  too lazy to find the link, but in some races,in a tight pack*, some legs have been cut by the brake disc, stitches required.   (* i assume front disc of one racer touched the calf or ankle of racer in left front).   On Mon, Mar 6, 2017 at 8:36 AM, via OBRA wrote:

Disc brakes are a disctraction folks. In my limited research, I've
turned-up a slew of unreported electrical shocks coming from electric
shifting systems --causing crashes. It seems that the peloton has been
silent on the issue since some of the riders have experienced
phenomenal, PR busting, sprint performances as a result of these
shocks. Indeed, it's not mechanical, it's battery doping.

It's gets worse: these electrical shocks can arc several meters in any
direction. When a rider experiencing a electric shifting arc also has
mercury dental fillings, the electrical anomaly can travel to a nearby
moto causing the moto rider to experience a muscle spasm in the biceps
femoris nearest to the emanating current --thereby bringing about a
moto steering action towards the current which thereby sends the
motorcycle on a collision course with the cyclist(s). In less dramatic
circumstances, sans moto, the arc induces a touch of wheels.

Further: some speculate that the introduction of disc brakes,
specifically disc brake rotors, provides for a canceling effect on
these shocks. Hence, true sprinters like Marcel Kittel argues for disc
brakes so that weaker sprinters won't benefit from eDoping surges at
the finish line.

-Its all fun and games until its your leg that gets cut.

-That they are rounding the edges indicates that there has been problems.

-OR are you all saying its OK for me to race with sharp things attached to
my bike, sticking out here or there ?! a few sharp knives, some ninja
stars, in my jersey pocket? And no handlebar plugs. *OR* do you want me
to "round the edges"? less safe, more safe, little tradeoffs everywhere
I personally think we should just outlaw crashing. No crashing allowed.
And no texting either.

I have been know to take file to too sharp chain ring teeth. (ie if you
brush up against them and they draw blood, yes too sharp. )

Disc brakes are a disctraction folks. In my limited research, I've turned-up a slew of unreported electrical shocks coming from electric shifting systems --causing crashes. It seems that the peloton has been silent on the issue since some of the riders have experienced phenomenal, PR busting, sprint performances as a result of these shocks. Indeed, it's not mechanical, it's battery doping.

It's gets worse: these electrical shocks can arc several meters in any direction. When a rider experiencing a electric shifting arc also has mercury dental fillings, the electrical anomaly can travel to a nearby moto causing the moto rider to experience a muscle spasm in the biceps femoris nearest to the emanating current --thereby bringing about a moto steering action towards the current which thereby sends the motorcycle on a collision course with the cyclist(s).

Why?

Because you gank on the brakes like a gorilla? I'm confused how this is
even a topic?

Disc brakes work a lot better, granted ... some gorilla slamming on a disc
brake can slow faster than someone with rim brakes behind them. But I can
slam on a rim brake harder and faster than some other riders. Should we
all measure our relative hand strength and be ejected from racing if we
have too strong a grip and can stop faster?

Maybe we should measure reaction time and consider someone with quicker
reflexes than "normal" to be a hazard and removed from racing too?

If you modulate/control your braking ... regardless of the brake style ...
you're a better peloton racer. Maybe we should relegate any one in the
peloton that weaves too much to the back - as they're unsafe riders?

I'm really struggling here trying to understand this ... why do you think
we should "consider disc brakes"?

Maybe crashing out you're afraid of cutting yourself on a rotor? Hell,
there a LOT of parts on a moving motorcycle that'll lop your fingers off if
you fall wrong.

I'm thinking lining the roads with 4" foam pads might help prevent road
rash too ... Dear OBRA - lets consider foam mattress pads on all roads
for bicyclist safety ...

Maybe since I weight 220 pounds - I should be allowed disc brakes ... since
I have more mass, and maybe my rim brakes won't be as effective as your rim
brakes if you weigh 140 pounds? Maybe a weight requirement for Rim -vs-
Disc brake usage?

Ok - so maybe my bias is clear? Disc brakes are superior, and it's a
choice up to the rider to use them or not ... but it's the riders
responsibility to use them safely in a race, with other racers around them.
That applies ... regardless ... of the item under discussion. I've seen
water bottles wielded with near deadly consequences in a peloton. Maybe we
should only allow hydration packs with water tubes so some careless rider
doesn't drop a full water bottle in the middle of the pack?

~~shane

P.S. Incidentally - all of my road bikes have rim brakes. All of my
cyclocross bikes have disc brakes. All of my mountain bikes have disc
brakes. I wish my road bikes had disc brakes.

Road racers please consider the safety arguments for and against disc brakes in racing. After my own small amount of research I've decided to use only rim brakes in races due to the apparent risks that discs pose to myself and others in the peloton.
