Gears for IM Moo Camp
Plan to do the IM Moo camp and only have a 12-25 (Ultegra) that came with the bike. I am running compacts but know I will need more gears for the climbs. Not sure all this matters but for disclosure purposes...
Shimano 105 FD // Dura-Ace RD // SRAM Red Cranks // Shimano Chain (not sure what model).
I was looking at the SRAM PG-1070 (Force/Rival) 12-27 cassette. While I was at it I figured a chain might be worth adding (Shimano of SRAM?!?). Bike is 4-5 years old but probably less than 2000 miles on the chain and 30% of that from the OS (trainer).
Appreciate any guidance.

Thanks Coach - not actually doing the race but hoping to benefit from a big bike weekend and soaking up knowledge from the group.
EDIT - Should I look at something more than a 27?
I am running a 12-27 on the back and a 52/39 on front. I have standard cranks, but 650 wheels, so it is a wash. I think you would be well served with a 12-27 on the back.
I will be running a 34/50 compact with a 12/27 cassette.
From a lil' peep - You'll be totally fine with a 12-27.
Compact + 27 is fine. FWIW, there is nothing very steep on the IMWI course. There may be a couple tops of hills, out of corner, etc that is 10% for a few pedal strokes, but the 3-4 legit hills out there (legit meaning long, relative to the others) are 4-7%. I think Timberlane is 9% for about .2mi.
i am running a 50-34 up front and a 12-24 on the rear, i know on hills it is hard to go the low watts EN way, thoughts?
