I was discussing flywheels with a few of the UMTR guys about aluminum flywheels and one of the opinions had my interest. The idea was that even though the inertia is greater with a steel wheel the aluminum wheel recovers RPM quicker between gear changes. I have a new aluminum wheel that I intend to use if I put the old Hays Mark XII plate back in because that 12 bolt adjustable plate is freakin heavy.
