The world's first, and still most reliable, 'split' rear sprocket
system for gearbox engined karts.
Carriers in 25, 30, 35 and 40mm bore, alloy or steel.
Steel sprockets in #428 or #520 pitch for all sized carriers.
We apologize, but these sprockets and
carriers are no longer being made.
At this time we have no stock at all.
