There are three chain rings... 48/52 and a 28 tooth granny. This works well with blocks that are 5, 6, and 7 speed where you have larger ranges and bigger jumps between gears. I know I could build up some 8 or 9 speed wheels but where is the fun in that ?
My folding / separable touring bicycle also runs a half step with a 50/53 and a 40 tooth granny which gives it nearly the same range as the 26 inch wheel Cascade and it uses a custom 7 speed block.
Will be loading this bike up in a week for a little weekend adventure...
1973 Phillip's 20 custom touring bicycle.
Both drives offer me excellent range and nicely stepped gears but you do have to know how to shift a half step to get the maximum benefit... with the larger middle ring my cruising gears tend to sit in the middle of the freewheel and this makes the drive more efficient as you are engaging larger cogs.
