I just ran that link by three experienced triathletes and they all said it was an exceptionally deal for an entry level tri bike, esp with 105 components. One said that at that price, there may be some upgrades to be had (better wheels, perhaps) but a steal nonetheless.

Congrats... I hope you get the bike!

(I was sorely tempted, but I have wetsuit purchases still to make, so will have to make do with aerobars on my road bike)
