Hey ya'll. I just purchased my new used bike. It's a 2004 KHS Flite 900 for $450 tax free. I visited the LBS and they said it was the right size but needed a few modifications to be the best fit. My question is, How fast can you ride a 6 mile course of flat land? I do have 5 streets to cross on the bike trail, but I want to get an idea of how fast I need to get. My first triathlon is in Sept. If you have done a sprint tri in the the past, what are your swim, bike, run times?
