After monitoring my current 2×10 (32-24 : 11-34) gear usage and comparing different oval chainrings I came to a conclusion, that Doval 30T 3032OCP would be good for my usage, but also ordered 32T 104bcd version.
- only oval that is available for 104bcd in 30T size with the 3032 mounting system and 99.5bcd
- “double oval” i.e. rapid transition to minor axis after power stroke on major axis (see mtbr forum for more pictures and details)
- cheap and easily available from ebay
