If performance issues arise, please consult the following table for possible solutions. For more information, please contact your
local dealer or SRAM Dealer Service.
Issue Possible Cause Cure
Stuck in Over-
drive/Loss of
1:1 Gear
Too little tension in shift cable Adjust the shifter by turning barrel adjuster on the shifter counter-
clockwise. If barrel adjuster will not provide sufficient adjustment,
reattach cable at the cable anchor bolt per “Shifter Installation
Instructions”.
Malfunctioning or damaged
shifter
Cycle the shift lever several times to confirm proper function. Replace
shifter, if necessary.
Contaminated or improperly rout-
ed shift cable housing
Check that housings are properly routed and that cable moves free-
ly within the housing. Properly routed cables will take a smooth path to
the cable stop and provide enough slack for handlebar and suspension
linkage movement. Clean and lubricate or replace housings if necessary.
Cable end pinched between collar
plate and frame or ISCG spacers
Check to confirm that the excess cable beyond the cable anchor bolt is
trimmed to the correct length and allowed to move freely. If not remove
cable from pinch point.
Contamination on overdrive pawls Clean and lubricate overdrive pawls.
Contamination inside actuator
assembly
Clean and lubricate actuator assembly internals.
Broken overdrive spring Replace overdrive spring.
Incorrect ISCG spacers installed
on offset ISCG tabs
Confirm offset and spacer configuration.
Stuck in 1:1/
Loss of Over-
Drive Gear
Too much tension in shift cable Adjust the shifter by turning barrel adjuster on the shifter clockwise. If
barrel adjuster will not provide sufficient adjustment, reattach cable at
the cable anchor bolt per “Shifter Installation Instructions”.
Malfunctioning or damaged
shifter
Cycle the shift lever several times to confirm proper function. Replace
shifter, if necessary.
Contaminated or improperly rout-
ed shift cable housing
Check that housings are properly routed and that cables move free-
ly within the housing. Properly routed cables will take a smooth path
to the cable stop and provide enough slack for handlebar and any sus-
pension linkage movement. Clean and lubricate or replace housings if
necessary.
Contamination inside actuator
assembly
Clean and lubricate actuator assembly internals.
Contamination in mechanism
assembly
Disassemble, inspect, clean, and lubricate mechanism assembly.
Broken overdrive spring Replace overdrive spring.
Incorrect ISCG spacers installed
on offset ISCG tabs
Confirm offset and spacer configuration.
Increased Drag Contamination in mechanism
assembly
Disassemble, inspect, clean, and lubricate mechanism assembly.
Wear or damage in mechanism
assembly
Disassemble mechanism assembly and examine gear teeth and pawls
for wear or damage.
Incorrect ISCG spacers installed
on offset ISCG tabs
Confirm offset and spacer configuration.
ISCG tabs out of spec Use SRAM ISCG cutting tool and face ISCG tabs perpendicular to BB
axis.
