I purchased these to replace some old wheels after confirmation that they were suitable for Campagnolo 9 or 10 speed road mechs. They aren't. The bolt holes are 6mm, when Campagnolo's are 4mm. The advert also claims all bushings for different systems are included, when nothing other than that pictured is included, just two jockey wheels. No additional bushings are included, so you would still potentially need to use the old spacers for these to work but these wheels aren't the same as the originals, so that doesn't work. Campy 9 and 10 speed mechs also have different upper and lower wheels, so you can see this is not the case with this product. I'm not sure why it's still listed with these details following recent problems/ discoveries. You may additionally want to read the small print about postage refunds. Read full review
