Actually Chi I think I should just get off the bike altogether. The aero saving would more than compensate for any loss in power. :)

So the largest difference between the 1x and 2x system in their biggest gear is 6W... just tuck your elbows and chin in, Allan!

If you're interested in the efficiency of larger vs smaller sprockets and chainrings you might like the following article:

www.velonews.com/gear/gear-issue-friction-differences-between-1x-and-2x-drivetrains/

It's all summed up in this picture:

So next time I get dropped on either of my 1x bikes I've got an excuse! (I still like the simplicity of the purely sequential gears though).

It would be interesting to see how the new Campagnolo 1x Ekar groupset compares with its 9T cog but I guess it will take an even bigger hit in the friction department.
