[MENTION=50586]msu2001la[/MENTION] I would think a 40 on road would be fine for most stuff, especially if you're not using the extremes of your gear range right now. I liked my CX bike with a 42 11-28 for most stuff including racing. It's gone through multiple gearing changes in the last two years (right now 50/36 with an 11-36), but it'll come back around to 1x soon enough.
