Which type of bike for me?

[KnottedYet]

I always plug Surly Long Haul Truckers, so, here I go again:
$980. Size 42 cm. Fender and rack mounts. Gearing to let you fly up the hills. Slack, comfortable geometry. http://www.surlybikes.com/lht_comp.html

Trek420 test rode one last year, and wrote a review. (she's a couple inches taller than you, and her LBS recomends she get a 46 cm) http://forums.teamestrogen.com/showthread.php?t=17451

Surly makes a wonderful sexy stable spry beaut of a cyclocross bike in a size 42 cm, but I think you'll find it too big because of the higher bottom bracket and such. But look at 'em anyway, just cuz they are pretty! $930. Comes with a double, but the spider lets you just toss on a granny if you want to make it a triple (that's what I did) http://www.surlybikes.com/crosscheck_comp.html

While we're on Surly bikes - there's always the pacer - can be built up well within that range....
