Currently, almost by accident using an old Sugino ovaltech chainring on my hack and quite liking it, although at 38T it’s a litle too big for some of the climbs coupled with a 12-27 on a 29er. It’s more like biopace than oval, but more oval than biopace was, if you get what I mean.
looking for a cheapish replacement for it, something 36T should be fine for my regular rides.
so, usual suspects, B labs and Absoluteblack, have their 12 ish degree clocking, makes kinda sense and eyeing the ovaltech seems about right (yes, I clocked it to the ‘right’ position).
however, I then came across These ovals on ebay for significantly less dosh.
looks like they have no clock, just large diameter when cranks are horizontal, smalest when they are vertical.
Anyone used them? AB and B-Labs would have you believe that this is wrong and to speak of such things is blasphemy (Ok I may have made that up), but any real world experience from the oval lovers out there?
