I just picked up this G.1 Explorer today at the local WalMart. Went for the 44cm - I used to be 5' 11" but age and herniated disks have shrunk me to 5' 8". Inseam is 29". The 44cm seems to fit like a glove.

Anyway, they had 3 of them assembled on the floor - I asked if they had one unassembled and still in the box - luckily there was one in the back room. I took it home and had it built and adjusted in about 30 minutes. Only needed minor derailleur tweaks.

A quick spin on my gravel road and up a local trail proved to be very promising - but it's too soon to give any sort of meaningful review. Seatpost has to go, though.

I've got a set of Easton carbon drop bars ($250) and carbon seatpost ($75) that I could put on it - seems a bit anachronistic, though. The bars alone cost more than the whole bike. :-) I think I'll just scrounge an aluminum post out of the parts bin and see if I have a more comfortable saddle lying around...
