I would appreciate it if the board could double-check my shift pattern for me. I am just now figuring out that not all chain ring/cluster combo's shift sequentially, so please bear with me.
My old Fuji "10 speed" has a 52-42 x 14-28 on it with 27" wheels, which would give the following in gear inches:
(14 16 19 24 28)
52: 100.6 88.01 74.12 58.68 50.29
42: 81.24 71.09 59.86 47.39 40.62
Which would give a shift pattern of : (L=52, S=42, etc.)
L14, L16, S14, L19, S16, S19, L24, L28, S24, S28
That seem impossibly complicated. I am missing something here or should I just memorize that pattern? Are any of those gear combinations that I should avoid? I haven't noticed any cross-chaining on this bike.
