The Wolf Tooth Giant Cog is a USA made sprocket designed to replace the 17T sprocket on your 10 speed cassette and give you a much lower gear for pinch climbs or when you are near the end of the ride and simply have nothing left. The Wolf Tooth Giant Cog is great addition to any 1x10 speed drivetrain.
CNC Machined and anodised from from aircraft grade aluminium for a minimal weight penalty and rapid shifts due to its lateral stiffness.
The Wolf Tooth Giant Cog is supplied in two types - Shimano and Sram. Both will work on any chain, but is only compatible with the following 10 speed models -
- XT 11-36t (CS-M771)
- XTR 11-36t (M980)
- X5 11-36T (PG-1030)
- X7 11-36T (PG-1050)
- X9 11-36T (PG-1070)
Note: Around 50% of Shimano derailleurs will require a longer B-tension screw. Once installed, if your derailleur will not shift to the GC without the guide pulley riding ont he GC (with the B-tension maxed out) go to your local bolt shopand pick up an M4 x 25 socked head cap screw or buy a wolf tooth b-screw with us ($3). This will allow the guide pulley to shift smoothly into the GC without any noise.
Note: You may be require a longer chain on your bike. Before riding, ensure the derailleur tension pulley does is not fully extended forward when in the GC sprocket. This is especially important with a full suspension bike. To test this, shift to the GC, and release all the air from the rear shock and then cycle though the travel.
