crazy-small chainring clearance for a track frame.
S300 Courier cranks have a narrow (40.5mm) chainline. Omniums are 42.5, which would solve the chainring clearance but the spider would crash the chainstay because Omniums.
Swapping to a normal road crank using the outer ring opens up loads of room. Obviously you then have to fuck with the sprocket chainline too, but it's worth it.

Absolute class.
That's crazy-small chainring clearance for a track frame.
