In less than 30 minutes, whichever SRAM groupset you have, SRAM RED, SRAM FORCE, SRAM RIVAL or SRAM APEX your bike can be transformed into a climbing machine. Our Pro teams, Astana Cycling Team, Liquigas-Cannondale, Omega Pharama-Quick-Step Pro Cycling Team and Saxo-Bank Team, have used WiFLi with great success on their SRAM RED equipped bikes for the extreme mountain stages. Why not you?
10 steps to transform your bike and climb all passes and mountains in the World. Follow the guide:
Step 1: Remove the rear wheel from the bike and use a chain plier to open the SRAM PowerLock or a chain tool to open the chain at a normal chain link. Make sure to follow SRAM’s instructions for chain assembly.
Step 2: Disconnect the cable from the cable-anchor bolt of the rear derailleur and remove the rear derailleur from the frame.
Step 3: Remove the quick release skewer from the rear wheel axle. Remove the cassette from the driver body using a chain whip and a cassette lock-ring tool.
Step 4: Install the SRAM 11-32 WiFLi cassette and torque the lock ring to its recommended torque (40NM).
Step 5: Apply some grease or mounting paste on the threads of the derailleur and hanger and mount the SRAM mid-cage rear derailleur on the hanger. Tighten the 5mm hex hanger bolt to 5-10 NM. Make sure that the B-adjust screw is in the correct orientation to the frame hanger. Reference the rear derailleur set-up guide for detailed specifications.
Step 6: Mount the rear wheel correctly on the frame. Take a new SRAM chain and follow SRAM’s chain assembly instructions.
Important: If you are not sure the chain is long enough, it is better to leave one inner and one outer link more on the chain and check again when the chain is run through the rear derailleur.
Step 7: Run the chain through the rear derailleur and check the chain length again before closing the PowerLock. The chain should not hang loose in the small-small combination and should not be fully stretched when shifting to the big-big combination. When you’re sure of the chain length, rotate the chain carefully so it is in a position on top of the chainstay rather than below. Close the PowerLock by holding the rear wheel, and apply light pressure on the crankarm in a clockwise direction until the PowerLock clicks into its closed position.
Step 8: Connect the shifter cable with the cable anchor bolt on the mid-cage rear derailleur, using a torque of 4-5NM.
Step 9: Adjust the lower limit of the rear derailleur with the screw H (H = High speed) so that the chain can’t fall off the smallest cog. The screw named L controls the upper limit (L = Low speed) so that the chain can’t fall off the biggest cog. Check the correct limitations by pushing and pulling the derailleur by hand against the limits. The chain must not fall off into the spoke side and not between the smallest cog and the frame.
Step 10: Shift to the small chainring and largest cassette sprocket. Adjust the gap between the upper pulley and the largest cassette sprocket, so that it is between 6 and 8 mm. Now the chain should shift quickly, quietly and smoothly between the largest cogs without rattling or decelerating. Fine tune the shifting between the cogs by using the barrel adjuster of the rear derailleur.
Go and ride wherever the road takes you!
