He has always seemed to have a very good top speed when climbing but not much of a jump, even at his absolute best. Porte needs to burn riders off the wheel rather than jump away. Liege probably suits him better.He said recently he no longer has the power on the climbs to follow big accelerations, it takes him longer to react which is deadly in one day races. Seemed that way in the Tour, he would sometimes get dropped and ride back at his own pace.
