Ultegra. 16.5 lbs.I got a great deal. I initially was going to cop from REI since they had the best deal in my area $2100. All my LBS wanted 2300+ until one said $1850 otd. They werent allowed to sell Cannondale instore since there was already a Cannondale seller 2 min up the street.My landlord said their was a big falling out between the 2 stores and that may be why I got such a good deal.
