12-26 on 52-39
11-32 and 50/34. Came on the bike and perfect for me!
Bog Std Giant Defy Composite 1 50/34 and 12-28 get me up all the Isle of Man's hills (inc Postie's Hill in Glen Maye that should be in a Simon Warren 100 best book) and over 103 miles of Stage 2 from Harrogate to Sheffield - which were not as bad as i was expecting.... did spin out @ 49.8 mph but hey it's all about the climbing and i can do all that on those ratios...
53/39 and recently changed to 12-25 from a 12-21. Much easier for climbing, though being 9spd it's not as nice as the 21, providing you are fit enough
I'm on 50/34 with 12-28 on the back. I didn't even get out of the saddle the last time I rode the Lecht.
I'd certainly entertain bigger gears for racing or TTing though.
