Bike helmet fit for the oblong

[DebW]

If you are talking about oblong front-to-back problem, like you have an aerodynamic skull; I've had good luck with Bell Citi and most Bell helmets. Giros are far too round for me, crushing my forehead while leaving wide gaps on the sides.

I have the opposite problem. My head is too round and I get squeezed by the helmet on the sides with too much room front and back. I've got a small Gyro that fits well unless I put more than one thin cap under it, then I get head squeeze.
