Cntrhub thanks for the input. That's some cool stuff to know for sure. I'm excited to hear what these will sound like and even more to feel what this bike is like on the road. He's runninga slightly larger rear sprocket than mine as well, which I believe will give him a bit more bottom end as well. Everything I know about building bikes. I've pretty much learned here on hc. And alot of trial and error along the way too of course. But I"m diggin trying to come up with something new each time. And your guy's input, opinions and knowledge are a huge help and much appreciated.....
