what should i run...i got a 32 up front....any recommendation for the rear...i ride alot of hilly sections with alot of downhill, i was thinking 16 or 18?

ouch

try an 18 or 20. isn't it nice to spin a bit too much on the first ride as opposed to blowing out knees? I think so. Mmmm, light gears, spinny-spin-spin-spin

Yup.....

....16 is gonna hurt. I ride a 32x19, and that works well for the long, extended fire road climbs that we have in these parts. 32x20 wouldn't be a bad gear to start out with either.

Listen to Eroman, he knows he shiat.

In gear inches a 29" 32:18 is roughly equivalent to a 26" 32:16. And 29" 32:20 = 26" 32:18.

I run 32:20 on the 29er.

hey thanks guys...i was wondering about it for the 29'r.....because of the larger wheel all the ratios would be different..
well im off to finish it up and take it for a beer run!!!

10% difference

A 29" tire is almost exactly 10% bigger than a 26" tire of the same width, so you'll want your gear ratio 10% lower to achieve the same overall gear.

A 2 tooth difference on the cog will come pretty close. If you run 32x16 on a 26"er, go 32x18 on your 29"er. If you run 32x18 now, go 32x20. I went from 34x20 to 34x22 when I built my 29"er, and it's just right for my terrain and riding style.

34x20 here vs. 34x18 on 26"

I find this ratio works well for my rooty, sometimes rocky terrain with short, but steep ups and downs.

32*18

32*18 on a 29" wheel is 51.7 gear inches with my lame assed caculations-where is Chester when I need his math skills.
No problems with the 2,000' climbs out here in Salida or ridding at 11,300' above tree line.

I ride 34:18 but I know of people running 30:17, 32:19, 32:20 and various others. Start at 32:18 and work from there.
