6) Lastly, out of interest since I cannot afford this solution right now, how does the ENO eccentric hub compare to a standard hub as far as speed is concerned - is there any sacrifice associated with the eccentric design?
I've owned two ENOs for six years. They work fine. Both are spaced at 135, fyi. No sacrifice (maybe $$) that I can tell. I also own a '85 Fuji road bike set up with Harris Cyclery track hubs on semi-horizontal drops. Can't tell the difference.
