I took my bike to the bike shop and the one I have should work. I just need to put a little metal or something inbetween to make it fit. I'm a handyman but putting the other ones on was impossible which frustrated the hell out of me. lol No worries I have all waterproof clothes and am getting waterproof shoes to go over my shoes. I just wanted fenders to help reduce the maintanence I have to do on my chain every week.
