Thats what i've used i prefer higher faster excelleration, i tend to find it makes you jump higher as you have to get used to less top end.
No one gonna suggest the KHE or Trialtech chains then?
I would seriously advise not using a "Crappy" chain, you and your face may regret it very quickly.
Huh? No it isn't you can go as wide as you want, just change the cross over. Its the frame that the width depends on, if the mounts are to close to the rim then your brake will rub constantly, if they are to far away then the pads will barely touch.
