SRAM!!!!!!!!

I used to have the hardest time with Shimano. I rode on Ultegra and I could not, for the life of me, get from the small to the big ring and vice versa. I literally had times when I would stop and get off the bike and manually adjust it.

I switched to SRAM and have been in love ever since, I am currently on my 2nd bike with it(riding Rival- it is equivalent to Ultegra) and am hoping to one day move up the line to Red, but right now Rival is perfect for me.

The double tap technology removes all issues that occur with the distance of the throw on shimano levers. I would definitaly look into it if you can. + SRAM is interchangable mostly with Shimano, so I bet you could switch out the levers and not have to mess with much else.
