I’m the exact opposite x7 shifter, x9 mech, can’t say i’ve had any issues that weren’t casued by abuse really. cheers though, just trying to get the auld bike working for as much cheapness as possible!
The shifters are the brains, an X9 shifter pushing an X5 mech around feels nice, but an X5 shifter pushing an X9 mech feels exactly like an X5/X5 combo to me.
Dropping down on the mech doesn’t make that much of a difference, but the X9s seem a lot more long-lived than X5… maybe not tougher (I’m not a mech breaker) but they wear less, and they’re more resistant to corrosion etc
X5 shifters and X9 mech on the pitch, can’t complain about the shifting, low end SRAM shifters are the old shape with the integrated indicator window in the clamp rather than the newer ones, but I cant fault it.
