That would seem to jibe with the empirical observation that it is sometimes optimal or even necessary to slide the axle back in the DO slots to make a 28 work. What is that if not increasing the effective chainstay length? Luckily the bike I'll be trying it on seems to have real long chainstays to begin with. I'm optimistic.
