I scored a free Surly 1x1 frame and I'm tweaking it ( gears, wheel diameter ) to ride it around as a brakeless fixed gear road bike.
However I've noticed that MTBs have markedly different frame geometry than road bikes. The seat tube appears to be proportionally shorter than on a road or a touring bike, esp. with the 1x1. The top tube isn't parallel to the ground.
I assume the frame is configured thus to make it more efficient for the rider to exert force in lower gears, thus making it easier to propel the 1x1, which is designed to be a single speed MTB, up hills with a lot of friction and resistance.
So, my question is, if I convert this thing into a road bike fixie, am I going to destroy my knees and waste a lot of energy due to the specific design of the frame? Is it just a matter of adjusting the position of the handlebars and seat? Is my energy wasted here, and ought I find another, better tailored - to - the - streets frame instead?
