Hi all,

I'm considering taking up mountain biking and am looking to purchase this bike:

However, I'm not sure whether to get a 17" or 19" frame. I'm 5'10" with an inseam of about 32.5", which seems to place me in between the two, though I've read that erring on the side of smaller is preferable. I know the sizing varies from bike to bike, but I really don't want to order the 19" and find that it's too big and then have to eat the shipping costs in order to exchange it. I also know that going to the LBS and getting fit is the best option, but I simply can't afford the extra that they want for a comparable bike. Any help is appreciated.
