Ultegra RD - Short cage vs Mid Cage
I pooched my rear derailleur and have to replace it.
What is the trade off in going with a mid cage Ultegra rather than a short cage? At my age, the prospect of throwing a 30+ tooth cog on the back for hill climbing is an attractive option. Is it simply a bit heavier, or are there going to be other performance differences?
Also, what is the difference between "Largest Cog: 30 teeth" and "Chain Wrap Capacity: 40 teeth"? How big a rear cog can I use with a 6700A GS Mid Cage Rear Derailleur?
