Thanks for the side shot, the chain looks good even without tensioner. I'd put a brake on though, 140mm would look super sweet.

32/15 is nice (I've been running 32/14). Could you possibly take a side shot? Oh and is the chain halflink?

As a Moto owner myself I must ask you: How did you manage the chain tension? It looks like you aren't running any tensioner nor eccentric rear hub. What gear ratio did you use and is the chain tight enough?
