Seriously though, there's no magical rim depth that suddenly starts producing dramatic benefits. 30mm is better than 20, 40 is better than 30, 50 is better than 40, etc. etc. etc. Rotational mass as a factor in bicycle wheels is a myth. Now, if you want us to talk you into a specific rim, let us know and we'll come up with all sorts of BS to make you more confident in your purchase.
