Don't know if this one exists (doubt it), but if I could build one up, it would look lilke this:
12 14 16 17 18 19 20 22 25
Basically, I find the 12 and 13 redundant. Any condition where I can actually push a 13, I can just as easily push the 12 (ie downhill....). The 11 is way too small a cog and really if I can use this cog in a triathlon, I am better off saving my legs and coasting (ie I am already rolling along faster than 60 kph). Where I want "tight spacing is 16-17-18-19-20". These are my flat and rolling terrain gears. Tight spacing here is great. Once I get beyond 20, I am hitting some steeper hills, so I am quickly needing to shift from 22 to 25.
By the way, I run a 48 tooth big ring. I spend all my time on the flat and rollers in the big ring. When I get into some serious hills, it is over to the 34. In that cog, the 34x(16,17,18,19,20) is really nice for a long sustained climb, saving the 22 and 25 for bailout when it gets super steep.
I really don't understand the utility of many cogs that start with 11-12-13-14...basically a waste of gearing.
What studly gearing are you 55 tooth guys using...is it something like 11-12-13-14-15-16-17-18-19 ?
