Disc wheel v zipp 808 firecrest



Would a zipp super 9 be much faster than a zipp firecrest 808 rear on a TT canyon speedmax. Would be using it for 10 and 25 miles races.


I would say 15-30 seconds at most over a 40km TT. If you already have the 808, then just buy an aerojacket wheel cover: http://www.wheelbuilder.com/aerodisc.html


What sort of times are you doing?
