for me it was worth it... my wife was starting out and with her smaller hands was having a hard time with movement on "normal" shift levers. I threw 9070 on her bike and it was so much easier for her to master. I took a cold chilly uphill ride with her bike and with frozen hands shifting was no big deal for me and I was sold.. my bike ended up with 9070 too.

it's really easy to adjust and customize as well...
