Shift Kit-the ultimate in shifting technology
MADE IN THE USA
This HD Shift Kit will fit almost any Chinese 2 Stroke and allow the user to shift gears using the bike's standard rear derailleur. This and our Standard kit are what you see in the YouTube videos. Take a look at the parts list in our installation manual to see what we supply in the standard kit. The difference between HD and standard kit: HD kit comes with our specially designed Heavy Duty Freewheel for those more aggressive riders and engines with compression mods.
The HD Shift kit also now comes standard with the complete 131.5mm Bottom Bracket Cartridge
Note that this kit comes with typical mountain bike style crank arms and requires 9/16" pedals. If you have a one piece crank you will most likely need to purchase new pedals.
