I was checking the range for a friend & stumbled upon this unusual mid season discount (17%). At £600 it was already keenly priced but nudging under the 500 barrier makes this a pretty good deal.
Summary for the lazy:
Aluminium frame with carbon bladed forks. 105 drivetrain (5700, 10 speed), Tiagra cassette, Prowheel Ounce compact chainset, Mavic Aksium ONE wheels. 9.5kg all in. And the usual lifetime warranty for the frame, stem, handlebar and rigid fork.
I use my Triban 500 '14 model every day for commuting & did a few sportives on it. Still a great bike & this is the next level up. i know looks are subjective but it looks good to me.
Update: Price has dropped lower but there still appears to be stock in S (As of 2pm 11/7/16). Awesome bargain.
