Thanks again for the helpful info guys.
For the best rolling, I would recommend 451 size wheels not 406. I talked a bit to the guys at Bike Friday who do 406 and 451-wheeled bikes and their verdict at the time was all their racers were using stelvios on 451 rims.
Just want to be sure here, but will the 451's fit onto the Swift w/no alterations to the fork or frame? From what I've read, the brakes will have to be changed out to fit the 451's, correct?
I have three sets of wheels that I swap between two Reach bikes..
Wonder if the 451's are equally as interchangeable with a Swift.
I've contacted the shop were I ordered my 406's to see if they can get the 451's too, but I might be stuck w/what I've already ordered...
Still curious to know how the 451's fit with a Swift though.
Domo arigato!
