Jay seems to like the custom set that I had on the XStream. On Jay's cassette I removed a few of the larger cogs and I also removed the 12T and added more mid range cogs for more cruising-speed options on flat land. Think of it as a cruising cassette with an over drive gear (11T) for down-hill and bail out gears for up steep hills. :)

Terry,

For me, the single-step, mid-range cogs you have added improve the rideabiliy of the bike. I really like the way it rides. My other bikes are jealous, because I've been riding only the X Stream. :)

This sounds interesting... What are the specifics on this set, through the nine gears? I've got an 11-28 on mine, and tweaking the middle range may be something worth doing.

Tooth count of individual cogs is as follows: 30, 24, 20, 18, 16, 15, 14, 13, 11. Right now I'm having trouble getting the derailleur to shift the chain to the 30 tooth cog as I enter a steep hill. Down shifts fine on the test stand and going slow on the flats. Going to have to play with the derailleur some more.
