Kyklos Featherweight and 25mm tyres

Bobblehatboy1975

Hello,

I have a kyklos featherweight road bike and I've been trying to get some 25mm tyres on, and hit problems

I've got wheels with 20mm internal width and I have 25mm continental sports tyres.

The back wheel is too big for the frame, the tyre is too tall.

Does any have a Kyklos Featherweight and managed to find 25mm tyres that fit?

Does any know of shallow 25mm road tyres they could recommend, please?

Thanks
Bobble
