SPROCKETS
SPROCKETS ARE SPROCKETS, RIGHT? NO! CAREFUL THOUGHT HAS GONE INTO THE DESIGN OF OUR SPROCKETS. ALL GEARS ARE HOBBED, THE MOST ACCURATE METHOD TO CUT TEETH. THE REARS ARE MADE FROM THE STRONGEST ALUMINUM, 7075-T6, AND ARE MACHINED TO AN 'I-BEAM' CROSS SECTION TO ENSURE LIGHTNESS, FLATNESS, ELIMINATE STRESS CONCENTRATION, AND PROVIDE SAFETY (NO HOLES TO CATCH YOUR FINGERS). THE COUNTERSHAFT SPROCKETS ARE MACHINED FROM 8620 ALLOY STEEL AND THEN HEAT-TREATED FOR STRENGTH AND HARDNESS. NOTHING OBVIOUS, JUST BETTER.

REAR SPROCKETS:

Specially made for us by PBI for over 20 years, our sprockets are machined from 7075 aluminum and are available in 530 and 630 pitches.
