Yea robin is a sustained power rider, his wattage at V02 is not amazing but his ability to sustain it and suffer is 2nd to none i think in this country. Ive trained with him a good bit and power intervals are tuff as hell, leaving you wanting to puke your ring after only a couple of mins, but hes able to keep hammering through the reps. Add this to his skill on the bike in general and its tuff to beat.
