I'm new to triathlons and have done a few olympics and sprints. Will try a half IM in 2013. The bike leg is normally my strongest leg although I'm not crazy fast but I find it the easiest. I can do around 19mph on a hilly course in an Olympic tri.
I ride a 2012 Tarmac Sworks sram red... Thinking about getting the 2012 Shiv Sworks.. how much faster, realistically will I gain from this kind of bike on the same hilly course?
