Could definitely be aero dynamics (or lack of such). Was on an Easton shallow rimed training wheel in the front. And please don't laugh, a 15year old road helmet. The back wheel was slightly better. I´m quite tall (and chubby) so it could definitely be that my frontal area and equipment need some work.

I'm by no means a power house so I don't want to go too big, but I think the 11 option seems resonable. There's a disc cover waiting together with my 808 zipp´s and an aero helmet back home so hopefully I won't run into this ever again :)

I don't get why you think I'm a troll BT_DreamChaser?
