Sounds a little pricey to run R1 wheels, you can get aftermarket for not much more...
The pricing I got from HARDRACING for just the rear marvic magnesium wheel is $1399.00 with standard bearings. Add $150 for ceramic bearings.
I picked up the R1 wheel complete for $229.00 {it had a galfer rotor on it}
rear sprocket................................. $73.00
ceramic bearings............................. $95.00
................................................----------------------------
total.............................................
$397.00
I added that new caliper hanger........$104.00 { you dont need it....... its cleaner with my arm}
....................................................-------------------
my total........................................
$501.00
If you wanted you could do it much cheaper.. I saw R1 rear wheels for $100-150.00 then add just a sprocket and go. Less then $250.00
If your talking about a set!! The marvic's are $2395.00 with standard bearings.
You can get a complete set of R1 wheels with rotors
and all for..................... $400-500.00 {with tires}
front axle.............................$160.00
