I found this site researching information on bike I ended up purchasing on line. I am a firefighter with 4 generations living in my home, working two full time jobs (98 hrs per week). I was lifting weights for building mass and swimming for flexability. I don't run sprints due to a prior ruptured achillies tendon and had to take some time off from weights and swimming due to shoulder reconstruction. I am back up and training again and want to do a sprint triathlon.I have already recieved some good advice/info from ny first post and look forward to getting more into cycling in the future. My bike arrived damaged so I'm still waiting for the repair shop to make needed repairs.
