Front mech woes
I'm building up a Surly Crosscheck with a mish mash of parts but I can't for the life of me get the front shifting sorted. I'm attempting to run a 48,36,26 Deroe crankset, LX rear derailleur, 12-28 8 speed Sram cassette, Campag Xenon QS 10speed shifters, Shimano RSX triple front mech.
The back works perfectly but I can't get the front mech to shift to the outermost chainring. The RSX front mech was originally on (and I assume designed for) a 46-36-26 crankset so I thought that it would shift ok with the slightly bigger outer chainring and the multipe clicks on the ergopower levers.
With the hi limit screw completely loose and pulling the cable by hand, the outer cage only just clears the outer chainring (distance, not height wise) and doesn't shift the chain itself. If I place the chain on the outer ring whilst pulling the cable tight it rubs on the outer cage whilst pedalling.
Now is it just a case that this front mech doesn't have enough travel? Or do Shimano front mechs just not run with Campag shifters? Or is it a derailleur positioning issue (something I always have trouble with!)? Something else? Recommendations for a new front mech that will run this setup if this one wont?
Thanks in advance!
