Hi, I'm new to the forum and I'm looking for some advice. I bought my first road bike in 2013. I didn't really know anything going into the bike store. I've been running for many years now and wanted to get into triathlons so I knew I had to get a decent bike. I didn't realize how much I'd enjoy riding! So I bought a CAAD 8 2300. I ended up riding a little over a 1000 miles this summer, and love it. But now that I've have learned so much more about bikes I feel like I'm a bit limited by what I've got. I'd like to go faster, be more efficient in power transfer. I love the CAAD, but now I've been looking at the CAAD 10 105. I'm just wondering how much of a difference I'm going to see if I upgraded and in what ways. I have done a lot of reading and understand the differences in the specs, but I was hoping for some real world experience. Thanks for any advice.
