Have not read through this thread.. but Barguil is an obvious one, also I believe Cattaneo should hopefully make a breakthrough, Litsenko, a dark horse could be Joshua Edmonson, but that is probably more wishful thinking and he anyways will probably only feature in a very limited amount of races. Otherwise their is still time for last year's predictions of Novikov and Silin to prove their worth this year.. Other obvious ones include Dombrowski and possibly Zakarin, who was been hindered by his doping ban.
In terms of the TPers, well much has been said about the Aussies and of course Bobridge though by no means a surprise should finally start to prove his immense talent though he is at Rabo. Hepburn has been in the shadow of Durbo and Bobridge but he is certainly talented. But Kennaugh is someone who has been labelled by the Sky management as a rider with bagloads of potential, his career on the road so far has been hindered by the track so this season will tell us a lot about him.
