I'm expecting a 46 tooth Thanet eliptical chainring to be shipped soon for my Jack Taylor fixed gear with a bolt circle that fits the Cyclotourist, Nervar, Stronglight arms with the really tight bolt circle. My question is: How does the wide part orient itself to the crankarm? I can have it perpedicular or in any of four other orientations. Its enameled and I'd just as soon get it right the first time. Does anyone on the list have experience with these? Hilary said that these were quite popular in the '30's and '40's. I expect mostly for time trialing, but I'd like to know more.
