I'm not trying to be awnry but no bikes come this way. Not even close. If they did you would have to shift the rear 7-8 times (on a 9 speed rear) to get from one end of the cog to the other, every time you shifted the front. This is still obviously not the case even with the new 2X10 mountain bike drive trains. It is more normal to expect to shift the rear maybe 2 cogs lower when changing the front 1 ring higher in order to get the next higher ratio. Lots of overlap is normal.
