[quote=msheredy]Watch he put the OEM pulley back on. Hey crazier things have happened LOL!

I also wonder which version he purchased? Aren't there 3 different sizes floating around these days?[/quote
Good point, original c3 pulley 65mm (two versions groved steel and non groved alum). Then came the c3 68mm called a midsize also two versions alum first then steel no groves either one (meant to run stacked with a 178mm crank pulley).Just my two centavo's. ILLCYA
