Is this suitable? Bike has campag veloce shifters

also need new inner, are shimano/campag inners the same diameter? I guess the stub at the end are different?
Say... That's a nice bike..

    I think the 650 are aimed to be used with 650 rims and not 700. I'm not sure the amount of vertical adjustment on the pads will be enough to compensate for that. To be safe, I would buy brakes aimed for 700 rims.

    As for the cables... if you change the inner, you better change the outer as well. I normally buy the cheap K:ble stuff and I find them valid

    Short reach calipers are no good, as there is a gap between the tyre and brake inside (plenty of clearence for mudguard)

    Ok,

    after a quick search... it will work... look here

    The Randonneur 105 has those brakes on 700 wheels. It looks like they're made for guards, rather than for smaller rims...

    Your brake is fine. The problem is that the wheel is missing :lol:

    I think this is incorrect.

    The Shimano R450 and R650 long drop brakes are for bikes with enough clearance for mudguards... the wheel size is irrelevant, what counts is the distance between the fixing bolt and the rim.

    If ithe rim is beterrn 47 - 57mm, from the pivot bolt then the the R450 or R650 are fine, less than that and you use a standard drop caliper.

    The R450 / R650 designations are a bit like 105 / ultergra quality IIRC. I went for the R450 on my winter fixed rebuild
