Is a (slightly) warped disc cover.........?

…faster?

Yes, especially if it’s been dimpled too.

Seriously, I have a slightly warped disc cover (on the drive side). I also have a race tomorrow and was wondering if I should re-install it or just use it as is. I’m wondering if there is any noticeable speed difference. It’s on a 60mm deep rim.

On a side note, I have considered hitting it hundreds of times with a ball peen (sp) hammer to make dimples. =)
