More bike speed wanted
I'm after a bit of advice from anyone/everyone. I've got a road bike which I use for my tri's. It's got the usual, carbon forks, handlebars, seatpost and tri bars. Aero spokes, Ali frame and basic Shimano 8 speed gearing and weighing in at 22 lb. I've put on Michelin slicks and fly. Away from training, what can I do with my bike to get more speed from it? I can't afford to blow a small mortgage on a flash tri bike or a great wheel set. I have been toying with picking up a tri specific frame, but what will this really give me over 40kms? Any help would be greatly received.
