Can anyone confirm to me what size bolts the eyelets on a CAADX take please? I couldn't get the supplied bolts with my SKS Chromplastics to fit and have just tried fitting a rack that came with M5 15 bolts and they also won't fit into the eyelets. I'm not sure if it's just over-spray from the paint stopping them but don't want to force them in case they are the wrong size. Thanks in advance.

    M5 sounds right, if you have any M4 and M6 fasteners you will be able to determine which it should be. I had the same problem when fitting mudguards to my Defy, M5 would not start in the thread or went tight immediately.

    I carefully ran them through with an engineers M5 tap, as like you came to the conclusion that it was paint build up that was blocking the threads.

    If the thread is M4 the hole(core diameter) through the eyelet will be just over 3mm and for M5 will be just over 4mm, helps if you have a vernier. I'd be surprised if it's not metric.

    Also, if you don't have a suitable tap but have a spare bolt, just file or Dremel a couple of flats on the thread so the thread disappears. This should be good to clean the thread out.

    Cheers, I'll try an M4 and failing that I'll borrow a tap.
