The disc breaks on my bike don't really extend laterally beyond where the bike rack will connect to the rack. The bike rack I'm thinking of getting (Topeak Supertourist DX) comes in disc and non-disc versions. Is there a reason to get one vs the other ? It seems like the disc version might not be as strong, but I'm not sure. If I don't need the clearance, should I get the regular ? (Picture is not perfect, I can take a pic from behind when I get home...)


Thanks.
