So you have a 2x8? But really more like a 2x7 since that 11t wouldn't be very useful other than to gather a lot of down hill speed.I'm just using an ordinary 8 speed casette hub with custo sprocket ratios made out of a number of different casettes.
The largest rear sprocket is a 36T and smallest is 11T.
I am using a 9 speed chain on 8 speed sprockets to give more lateral clearance between adjacent sprockets when the larger diameter sprockets flex under heavy load. Works well and KMC 9 speed chain lasts just as long as 8 speed chain.
From memory my rear wheel ratios are: 36, 30, 25, 21, 18, 15, 13, 11
The non redundant sequential method you could use would be:
1(1-4)
2(4-7)
For 8 sequential non redundant gear ratios.
As for the flexing on the cogs, have you tried riveting them together?
