Following the conversion sheet from the 1970s I ordered a pair of 2.50 x 17" tyres.
The ones I got are a dual purpose so hopefully they will handle any thing I try when out riding.
Fitting the tyres was easy, the front one went on no trouble and the wheel slid nicely into the forks.
The rear one, again was easy to fit. that was when the trouble started. I had to remove two small
bits of frame bracket to stop the tyre rubbing. an afternoon spent under the bike cutting and
filing sorted the problem.
Next job will be to fit those handle bars.
