Disc wheel for 7 mile TT ???(2 posts)

Disc wheel for 7 mile TT ???Andy

Will a rear disc wheel buy me any significant time in a TT as short as 7 miles? I'm running Rolf Vector Pro's which are more aero than standard wheels. An additional 45 second savings would be my decision maker.

I'd think it's more like 5 seconds, vs. a Vector Pro. Run the numbers. Of course, it matters how fast you are going. 25 mph, I'd guess?
