Ola.my next bike is going to be a fixed gear mountain bike. I've ridden single speed for a while now and have an idea of what gear ratio suits me any my locale. The fixed project is on a tight budget so i don't want to spend loads on sprockets and chainrings getting it right. So my question to the masses is, is my preferred fixed ratio likely to be the same as my s.s. Ratio or should i go a bit higher or a bit lower? Cheers people
