I just bought a Z1 TT flywheel because it does not seem likely to warp and has seems very light. I have tried a Fidanza alum one in the past that just hummed and provided no notable performance gains, so I have used the factory FW for the last 10 years. What are your thoughts on the Z1 flywheel, from people who have used it?
