I am putting together the final touches after ordering my C59 Arte Decor with Chorus 11. I have ordered some FFWD Tubular wheels which are 45mm depth and I was about to order some tires when I wondered if there were any cearance issues I should watch out for? Ideally I'd like to go 25mm to have the best chance of avoiding flats but the Vittoria's I'm looking at also come in 21/23mm as well. Anyone help me out? Cheers.
