Creo and chainring/cassette configurations

[Elkman]

I seldom used the 3 lowest gears with my Creo and so changed to a 11-34 11 speed cassette and replaced the rear derailleur with a Shimano Ultegra designed for 11-34 cassettes. I like the tighter spacing of the gears and the bike only weighs 27 lbs so even without the motor it is not a problem going up the steepest grade. On tours with my road bikes I used 12-28 10-speed cassettes with 48/36 front chainrings. My Trek 5200 has a 12-25 cassette with 53/39 chainrings and the gearing is plenty low enough with no touring load.
