PSI has them. Ron Ribolzi poured it on to win gold medals in the
I.S.D.E. qualifiers and to win a national enduro. In one three-day
qualifier, he never let up while the other contenders stopped
to change front and rear sprockets, sometimes twice . Rnally,
they asked how Ribolzi was able to keep going. "It's the PSI
sprockets;' said Ribolzi.
Ribolzi does change sprockets for different events. PSI has a full
line of sprockets , countershaft and rear. Standard and all optional
sizes are avai lable, 30 to 72 teeth for selection of desired ratios
matched for event, weather cond itions or altitude. Choose from
heat-treated, steel countershaft sprockets or 7075T651 aluminum
rear sprockets for torturous conditions.
Anyt ime you know you'll need to keep going, get PSI Sprockets.
ASK FOR THEM BY NAME.
MADE: TOUGH!
