Hi,
i don't think, that they really work fine with gripshifters. Cause when shifting you're twisting your hand across the grip(as i noticed by myself) thats why my grips lok like a slick after one year
. Therefore i think if there's such an (how to call it, unround, not round, asymetric) grip it should be al little more difficult to shift. How about a better and ore ergonomic handlebar?
Greetings
