The dual position seatpost did catch me off-guard i must say...but I wasn't going to let anyone else buy that bike out from under me because of that. I'll probably contact jamis at some point and ask about availability of the other post...you know...the one they SHOW it with.

about the 670 and 671 it is the 50th anniversary edition. They don't make them in rosewood anymore because it isn't considered "green" to use rosewood...which is true. the white leather actually grows on you after a while.

I am far from loaded. I am just a poor little industrial design student who runs a gallery full of kick ass designs of which I only own a small number of.

back to the bike:

this bike accelerates like nothing I've ever ridden. Its just fast. I cannot WAIT to take it out on the velodrome in Colorado Springs this summer.

It also came with true track tires that are super thin and soft. I'd say they are only good for 500 miles...on an INDOOR TRACK. The stem leaves little to be desired as well. Just ordered my 100mm 17 degree +/- Thomson X2 to solve that. The saddle is absolute garbage too. gar-bage. Its sooo cheap. got an SLR on the way

also, for any of you who are still interested after an already long post...the down tube is very very thin tubing. very thin. they get away with it being so thin because of the shape, which is almost triangular or diamond shaped ,and the size of the tube. Just...don't crash.

the long and the short is this: the bike is super f'ng stiff and light. the whole bottom bracket area combined with the crankset means serious power transfer. like i said, this bike accelerates like nuts. the replaceable steel dropouts are nice.

if anyone has any other questions about this bike let me know. I know its hard to find anything about it online so I'll try and help anyone who is interested in the bike. I'll try and take better pictures too once i have the steerer tube cut down w/ the bars lowered and with the new stem & seat.
