I'm stuck on 9-speed. Why change? For one thing, I have zero use for a cog bigger than 12. I rarely needed or used the 54-13 I could put on my racing bike when I was 24 and at the strongest and fastest this body would ever see.

I elected to go with Campy 9-speed when I built up my current bike 8 years ago. I love the 9-speed, I have (2)12s and 13 and 14 tooth small cogs and use all of them on two different wheels. 13-23 gives my great gear choices. 14-25 the same choices less a fast downhill gear.

At the Smuggler's Notch (Cat 3-4) race 40 years ago, I should have won riding a 54-14. I didn't due to being dumb and having not pre-ridden the finish; it had nothing to do with my gear choices. That race went up, then down the backside of the 1000' Smuggler's Notch pass. 55 mph descent. The two of us driving that race were myself riding without a 13 tooth cog and a junior on a 52-15. Big gears aren't everything.
