I think that chainring is a 650c

Al Letorneur's chainring was considerably bigger, IIRC.

Here is a pic - also note that unlike more modern record attempts, Al wasn't TOWED by the pace car up to a near record-breaking speed, and then released for a brief sprint. He pedaled that bike up to speed.
Bike was made for the record attempt by the constructeurs at the Schwinn Paramount shop.

Here is Jose' Meifret's bike for good measure. 130 tooth chainring and I believe a 15 tooth cog in back.
Meifret was famous for surviving a terrible 80+ MPH crash during a record attempt, and then recovering and doing the attempt AGAIN on his way to establishing a new record.
His biography was entitled "My Rendevous with Death" !

To stop it from becoming an aero lifting body.

Not that this is a car forum, but the pace car is a full blown Porsche race car - that thing on it's own is crazy cool, but then throw the fairing and the tricycle in the pic...unreal. I can't even imagine it...

Do you not wonder why they are not all backwards? ;)
