Re: Aluminum billet covers- any sound difference?
A few grams here, a few grams there- has always been the cycling way. "An ounce off the wheels is like two off the frame" is what Olympic cyclists used to say.
I use titanium allen bolts on the covers. With an aluminum sprocket, bolted directly to a large flange hub with titanium bolts, eliminating the heavy chain tensioner completely, and a 415 Trike Industrial chain at about half the kit chain's weight, the kit weight has really dropped quite a bit. Now if only we could get a smaller plastic frame tank with a lightweight vented cap.
I'm not a souped up kind of builder- you can tell.
