I am just starting to really get into cycling. I have been riding for about a year on a used road bike but I am planning on purchasing a new bike this summer. I am looking for a good road bike that I can train on and participate in centuries (100+ miles) with. I have been doing alot of reading about how to find the right fit in a bike but I don;t really know where to start when it comes to brand names and such. I am looking to spend about $800 dollars on the bike and I am also looking for a heart rate monitor that I can get for around $100. Thanks
