I'm new to all this but found this forum when looking to see what people were saying about flat bar bikes.I'm interested because I've just decided to put flat bars on my Specialized Tricross Sport. I've had a couple of flat bar machines previously and found they suited me due to my being a once was a Rugby player. By the way I'm in New Zealand so rugby might be a bit unknown to many of you in the U.S.
My interest in biking is fitness and health - following on from cancer 3 years back - I ride around 200 plus kms per week and currently training for a charity ride around one of the bigger lakes here in the North island of NZ. By running my tricross on narrower tyres I've improved its speed but can switch back to tyres with more grip for some light off road.
