I am currently using a 42/53 front rings with 13-26, 8 speed in the rear. I am having a bit of a problem on bigger climbs and was wondering if changing the front rings to 39/52 would make much of a difference. Any advice from those with this experience? Steve
Three on the front = one on the back.
In other words, if you change to a 39, it will feel as if you had a 27 in back.
.
If you have Shimano, you could go as low as a 38, with a double crank.
Assuming the above information provided, IMO, no you won't notice much difference. I suggest going with something like a 13-28, 13-29 or similar in the back with a 39 in the front. Or, if you are up for it:
1. Compact crank up front -- 34/50 or 36 /50
2. Triple up front
Rule of thumb (and you know how thumbs are), going back to that days when everybody rode a single speed, unless they were a Tourist.
Still used for track guys.

All I know is that there ain't THAT much difference between the 42 and the 39. BTDT.
I DO know that there IS a distinct difference between a 23t and a 24t big cog. BTDT too!
To the OP: here's yer chance to upgrade! Go compact! Woot! Little gears that act like big gears. Rode the cross bike to work the other day with the 34/44t gearing in the front and the 'hills' between Morgan Hill and Gilroy weren't NEARLY as big. 'Course the top speed wasn't what it coulda been...
