1982 saw a 102mph top speed on rollers.

Here we see Dave Legrys beat it with a 126mph top speed- pushing a 232″ gear.

As TRACKO says- Now that’s a chainring.  Good find.

PS- you can come sprint with us on February 13th at the Counterbalance Benefit at Funhouse.  It takes place at the NOT QUITE  VALENTINES DAY SCAVENGER HUNT. There will be prizes, as well as a raffle for a bike and other great stuff.  Proceeds raise money for Team Counterbalance and their annual cross race.
