Well, I uh, converted on Saturday. Yup. Last big ride on my upright sent my back south and I have been miserable not being able to ride since then. The new bent is like a godsend. I don't seem to be having problems with sore bent muscles so far. I can't tell you that I have years of experience and never looked back but I can tell you that I went from 1 10 mile ride a week back to my 24 miles every morning again without pain. I am rediscovering my commute that I have ridden every day for the past 6 months by being able to actually see things and scenery on the side of the road. As far as speed goes I am faster on the flats already and only lagging .5 - 1 mph hour on the local climb and I am hoping that will soon close as I ride the bent more. I have a Strada by the way and it isn't the cheapest (it definitely is not the most expensive though) but for me $40 a week gas savings add up quick and I ride more than I drive so it makes sense to go for quality and something that will be durable and dependable.
