I'm new to road bikes and have questions about shifting. I've calculated my gear inches (12-23 9 speed cassette and 29,44 chainrings...its a mountain bike with disc-specific 700cc road wheels, swampable with 27" MTB wheels if I choose).

The transition from the small chain ring to the large requires me to simultaneously drop down four gears on the cassette. There is no other spot on the gearing tables that would prevent less shifting without a significant change in resistance.

How do I 'double shift'? I tried simultaneously shifting the rear and front once, and threw the chain on the front. How do I, and when do I, up or down shift four gears on the rear, while dealing with a chainring shift?

Thanks so much, again.

When shifting to the big ring, first shift a cog or two bigger, followed immediately by the big ring shift. This helps maintain cadence. When shifting to the little ring, I make the shift to the little ring first, followed by shifts to smaller cogs, as needed. The little ring shift is where campy ergo really shines. Ergo levers permit multiple shifts to smaller cogs with a single stroke of the thumb button. Quicker and more efficient.

The idea is not to get the your cadence slowed down. A low cadence makes shifting difficult and reduces efficiency, as you work to bring it up to the normal 90-100 rpm.

One of the easiest way to spot a beginner is by the 60 or 70 rpm cadence.
