Okay, I am going to start road cycling so I'm a newbie. I have done a lot of research and web crawling and I am finally on the home stretch to buying my bicycle, BUT I am stuck with a budget of R5000 for the bicycle and all the necessary safety gear etc???? I can get a 2007 Raleigh RC3000 for R3000, or I can get a 2005 Raleigh RC6000 for the same amount. I know the RC6000 has 105's and WH-R550's. So kudos to everyone giving any knowledgable and informative answers!!!
