Yes and Murphy cheated death that day, being pulled up into
the train car at he very last second. We all grew up with
Jose Meiffret's adventures:

and of course John Howard's 1980s attempts. But this, I
think, is truly a step beyond.Â* Hats off to her!



Interesting that #1 the front fork rake is reversed from what we're
used to and #2 the front tire is off the rim after the crash. Was it
the front tire coming off the rim that caused that crash?


Right, speed record bikes have very different geometry - the
very last thing you want is snappy handling.

I don't know about the tire but tires/tubes/valves are a
real problem as we don't have 'speed rated' products for our
wheels as racing cars and motorcycles enjoy.

John Howard's Schrader valve pins depressed at some high
RPM, the solution being a classic metal valve cap with
rubber liner.

We were just talking about that yesterday. I think that Goodyear makes
speed record tires for most records. I understand that Goodyear is
about to start making normal bicycle tires again.


Such that "making" means buying them from the low bidder in Asia, then yes.


I've seen them, in a bike shop in Akron Ohio, the home of Goodyear. But
I saw no evidence they were actually made in Akron.

However, a couple articles state that a Goodyear team in Akron developed
the rubber compounds used, which supposedly vary for the different types
of tires.
