Since the circumference of a 650 wheel is smaller, it would make sense. For the same gear ratio, you would be a bit slower on 650. Not sure this requires changing your chainrings. Unless you are already overspinning your 50x11

C'mon, Bob. This is the triathloon forum, of course he's talking about 650C.

Use a handy gear calculator to express the various combinations of wheel size, tire size, chain-rings and cogs as Gear Inches for direct comparison.

My two cents - I ride 650s on my tri bike and 700s on my road bike. I find I can use the same components on both and really do not notice that much of a difference. Gear for 650s is just becoming harder and harder to find.
