I have had a boardman hybrid compo 2011 for the past 5 weeks and I have been doing at least about 60- 80 miles per week. I have commuted about 6 miles in less than 30 mins and my fastest recorded speed was 17.6 miles/hour. I find middle front gear and the 3rd lowest rear gear comfortable. My major problem is that I tend to forget to gear down while stopping. Considering I took up biking less than 8 weeks ago. Am I utilising the potentials of the bike well. What was the fastest speed anybody here had done on the bike? And how did you achieve it?
