Your only half right about the T9 Bioshield; your right about it's "probably" the best for wet and muddy conditions, but for dry conditions Teflon lubes are superior in antifriction. Bioshield will have more friction on the drivelined then Finish Line Teflon Plus will have...BUT, will you notice it? maybe not but I can! I noticed a smoother free moving driveline using Finish Line Teflon Plus over any other product I've ever tried including T-9. BUT, if I was going to do a lot of riding in the rain, mud, or snow then you bet T-9 all the way; I use it on my mtb when ever it's going to be a wet ride; but with wider tires, wet conditions, etc, speed isn't necessary thus friction is not an issue.
