Re: Heavier duty clutch cable ?
the best cables i've found are Jagwire Compressionless Mountain Bike Cables.
they've got a kevlar lining in the housing, and a teflon insert, too.
it's a huge difference in feel over the mushy stock cables.
the problem with the clutch requiring a lot of force is another story, though, and a new cable won't help much.
if you take the clutch cover off, you can back the flower nut out till it feels right. it might take some trial and error, but it's easy when you figure it out.
my clutch is effortless to pull.
