Posted: Tue 1st Jul 10:13am Post subject: I Fell Off Climbing Dyers Pass In The Ice This Morning!
It was first time up there in a few weeks, probably a stupid idea given the -2deg forecast overnight, but Danose made me do it!

anyway, what fool does NO hill work over winter?
I was not far short of the Takehe, so only going slow, my wheel just spun out on black ice.
Must have looked quite funny as I proceeded to fall over again on the ice as I struggled to walk across the road in my road shoes.
To add insult to injury a roadie chick came breezing down as I was gatherering myself - how did she get up/down without falling off?
I also bent my beloved Tiagra rear mech (rest of bike is Sora) into the rear wheel. luckily managed to bend it back to a position so I could ride it again and limp into work...
So, how do you do hill training at this time of year without getting hurt?
It was around 08:30 so the sun had got to a lot of the road
Are some climbs less icy than others?
And what I am going to say when my wife sees my gravel rash..?

I rode up dyers pass this morning and it was pretty slippery by the sign of the takehe. I find it's not quite as slippery if you ride further out from the side of the road

Try sticking a nice knobbly 2.1 tyres on yer rims
Yes, have to see the funny side of it...
Another stupid move was pumping the skinny 23mm tyres up to 140psi this morning, not the best for traction...

Hill repeats up hackthorne to the cup after work, morning in winter is a crazy time to be doing hill work!!
Trouble is that means doing it in the dark (and usually wet) conditions - a different type of hazard

I was quite far out, but man, it was so slippery!
I was glad it was going up I had my spill and I didn't wait until the descent, could have been a broken collarbone or something... I think I'll take a better look at the weather forcast next time before an early morning ascent ...

I always like to think something good comes out of something bad (I always used to have lots of graphic pictures of my motorbike accidents when I was younger).
In this instance I believe a crash rating system is required, then I will feel I have quantified my experience.
Rate your crash:
Score 0-10 in the 3 categories below, then multiply them together to give a final rating out of 1000.
a) Severity: 0 = no injury to rider or bike, 10 = grievous injury to rider and/or bike
b) Humility: 0 = no-one saw it, 10 = done in front of many bystanders while showing off
c) Avoidablilty: 0 = nothing could be done to avoid it, 10 = the warnings were all there, it was totally avoidable
So, my score this morning:
a) 2 (gravel rash and bent rear mech)
b) 7 (a number of witnesses and subsequent fall walking)
c) 9 (I knew the road conditions and had warning slips before I actually fell off)
2 * 7 * 9 = 126
Now I feel satisfied!
How does your favourite crash rate?

I lost traction on my driveway this morning (I'm on Hackthorne Road) - that was enough to make me very careful for the rest of the ride to work
I looked out the door at the patches of black and plate ice and decided that having
munted myself in those conditions 2 years ago today was a good day to drive in
I then discovered the battery in the car was dead due to the cold (had been meaning to replace it since the start of winter - doh!)

actually not so silly - on ice you need pressure melting for grip - so a larger contact
patch (either 23s at low pressure or big fat mtb tires) actually give LESS grip. It's all about kg/contact patch (which is why you can drive you car/motorbike across an icy patch you'll fall over on foot on). This is why studded tires work (put all the pressure thru
tiny contact points - studs pressure melt in and grip)
as for the chick who made it down - momentum is your friend

What are you complaining about? I discovered that my doors were frozen shut, and after hosing the car down and getting inside I discovered 3 inches of water inthe passenger side well. gnikcuf great door seals, eh?

How does higher pressure and it's associated reduced contact patch assist in traction on ice?
