Definitely a good way to get an idea, but it can deceive you. I ride a Soma Rush which does not have forged drop outs. The Rush is by no means the best frame in the world, but it is still a high quality steel and makes for a good foundation for a fixed gear. Just saying that - like with every rule - this one has exceptions too.
