I have a 2005 Schwinn Super Sport flat bar road bike. Has SRAM SX4 paddle shifters.
I have 1000 miles on it, & have had minimal service on it (free lifetime adjustment at Performance Bike, local store).
I began to experience some shifting problems:
1) rear (8 cogs)
when I shift to bigger sprocket..it slips back to the original (smaller) sprocket
can't shift from medium ring to small ring.
Does 1) mean that the shifter is at fault?
I played with the front derailleur for 2), & seemed to make some progress by adjusting the H & L screws on the derailleur. Then, I got greedy & thought I could take apart the SRAM SX4 front shifter..while it was still on the handlebar. BIG MISTAKE. When I unbolted the lever, a round clip fell out. When I tried re-installing the lever..it wouldn't shift.
I then took off the shifter, & disassembled it by removing the 3 small Philips screw. Pieces fell out everywhere (see picture). I couldn't figure out how to put it back together.
Anyone know of an assembly diagram?
I was amazed at the amount of nylon material (which holds the cable). Am I better off just buying a better set of paddle-shifters? REI sells the X.4 for only $26.00:
$8.95 for the front X.4 shifter
I could buy a X.4 replacement set, or upgrade to a better set. Can someone recommend a good brand/model?
TIA for any help/advice.
I found a manual here, but no assembly instructions:
