I have a 90 mm stem on my Cannondale quick four. I want to raise the handlebars up to take the weight off my hands and the Richie comes in 90, 105, 120 lengths. When I talk to Richie they said that you want to make sure that if you're raising the handlebars that the handling is the same so I'm wondering if the 105 or 120 lengths would be better to raise me up but not shorten the distance that might affect The handling. Does anybody have any experience with the four axis adjustables?
