My brother has been offered a Certini. This would appear to be made in the Cornwall/Plymouth area. It has Columbus Genius tubing and a mixture of 105 and Tiagra. It also has Mavic Cosmos wheels.
I'm not familiar with the tubing or wheels and would appreciate a little help.
The components don't sound like anything special, so ignore them they're probably worth nothing. The basic Cosmos wheelset is quite ordinary, so again, not worth much 2nd hand. But a Genius tubed frameset could be very special and worth a lot. I would be surprised if a frameset of this standard was sold with cheap components, so I'm guessing the whole bike isn't an 'off the shelf' model. Do you know how old it is ? I think it's pretty much the best steel tubeset Columbus made. I don't know much about frames that the Certini bike shop had made, and whether they're particularly special or not. I don't even think they're Italian made, despite the name, although if they were British made, that's not a problem by any means. Details of the headset will inidicate the age. A picture would be quite useful if possible.
