Shimano and SRAM are the same.
Something tells me you do not speak Campagnolo. Campag make levers that are meant to be modified so you can run them with different speed kit, Shimano/SRAM don't. Only they try and make it some dark art that us mere mortals cannot understand.
Are meant to be modified? You must be joking.
Obviously you can't read a technical document as changing an 8S to 9S or 10S is relatively straightforward on the old Ergo Power.
Has anyone had an 11 speed RH Ergolever modified to run as 10 speed? And exactly what Camapgnolo 10 speed rear mechs can you run a modified RH lever with - every Campag 10 speed rear mech that there has ever been? Thanks in advance for any helpful comments.
Take the spec sheet of the Centaur 10S Ultrashift and compare it with an 11S. Spot the difference, order the appropriate parts and start replacing them. Even easier than on the older Ergos.
Campag make nice kit, but are utter crap when it comes to putting out meaningful and understandable product information. Really, the company is just not up to speed or not clever enough to get their after-sales care working well
Those docs are meant for LBSs and their technical staff not the general public. If you want to mess with your stuff that's your problem.
I don't see why Campagnolo should encourage it.
