about to buy this derailleur
what is the difference between the low and high clamp versions?
thank you very much

i am drawing a blank, but i think:

up swing = bottom pull cable under bottom bracket

down swing = top pull cable from above

or some combination of that. see if someone else can confirm this

chances are you need high clamp. your frame should say??

Hi clamp version shown. Low clamp version is for frame that do not allow the high clamp position

I've found the top swing to be more universal but some full sussers need bottom swing to allow for suspension movement. Now Top pull or bottom pull is self explanatory depending on your frame.
