Speeds on Strava

[JMAG]

@Dan B you may have missed my post on the 1st page of this thread, but I carried out this experiment on Saturday, albeit unintentionally. The shifting of CoG will have a minimal effect on deceleration and I can tell you the rear wheel will come down several metres past the braking point. This was with a metre or so stopping space

Ouch @JMAG that's a nasty arrow through your knee there.
GWS.

I looked at strava the other day and a segment near me had the top speed as 180mph!! Or it might have been kph.

Was the athlete a Mr Nibali by any chance?

Strava must be wrong.......it gave my average speed as 9.4 mph.....no way! Never gone that fast an average yet (see my beginners thread)! Best so far was 8.4 mph. Or am I just getting better? *polishes her personal best award*

This is what I got when I tried to instantaneously stop from 20mph lzst year (pedal strike on fixed)

I and bike still travelled further than the with of a 2p though.

 

[Cannondale Lady]

Nasty!

I stopped on the diameter of a 2p once. Unfortunately my means of braking was the back of a car.

I thought this might have been @young Ed until I read the link!!

I can't wait to see Young Ed's video, although there could be a delay between filming and posting depending on whether his local hospital has WiFi.

There's a segment on my commute I have gone for a few times and I it in 3rd. Current KOM has an average speed 20mph above my effort!

 

[JMAG]

20mph is a lot uphill. Maybe it was a pro or maybe they cheated? There's nothing to stop anyone jumping in a car or on a motorbike with Strava on.

 

[jonny jeez]

I would much rather be able to be competitive climbing than going downhill, downhill seems to be more about how much your prepared to risk.

Sort of like motorsport then.

 

[Mr. Cow]

They have probably been driving with Strava running.

32.186kmph = 8.9405 m/s or 8,940.5 cm/s

No one seems to have bought you to task for this.

There's a 100cm in a metre (the clue is in the name). so it's 894cm/s, or 8,940mm/s. So (assuming your other calculations are correct) only 30gs. So he probably wouldn't actually be crushed by the force, as he presumably has strong muscles and bones to apply that braking power with his hands.
