I'm not sure on the breakdown, but I paid 345 OTD for the 120/70 front 003 Pro in Medium compound and a 180/55 rear R10 in Medium compuond from
www.cyclemall.net. It's an actual shop in Tustin, CA, but I'm sure you could internet order from him. I think he says he is going to normally charge 390 for the set of R10's in Medium installed on the rims OTD.
The 345 OTD was the installed on the rims price. He gave me 30 bucks off...cause he's cool like that. lol
