Ask the pros and its says front wheel not rear wheelmadness
why do all the pros use disc wheels on the back then not tri spokes?
It says if you get a 3/5 spoke you'll save 42 seconds over a 12 spoke wheel, it says get a rear disc and save 29 seconds over a 3 spoke
So my deduction presumes a disc rear wheel is quicker than a tri spoke rear wheel, unless i cant read properly
