We think that there has been some error in
the wheel and tyre weight which you have been given because
the weight figure for our 20" wheel and tyre comes out at
136 lbs. pair. Otherwise, we think that these figures
are reasonable.

We should like to point out that we hope to
reduce the road spring weight as time goes on.
