I am somewhat new/new again to triathlons. I did a sprint tri a few years ago but never seriously got into it for various reasons - work, time, etc. Things have changed now and I want to start again. I have a decent level of fitness still and decnt time to work out. But I am totally clueless when it comes to the bike. I was thinking about upgrading something on my bike (cannondale w/ shimano 105 components). Funds are somewhat limited right now but I can spend some money and plus my birthday is coming too. I had my bike in a shop a while back and they suggested upgrading my pedals first, said what I had on there was pretty bad. Honestly I wouldn't know. What advice would more experienced people offer? Not totally sure what I can spend, 2-300 at least, maybe a bit more if I wait a little longer.
