Too right ! - previous threads here have been all over the shop on this strength business...
There is also the minor matter that original featherbed frames come in 4 versions, of about 20 minor sub-varieties, at least. !?
Genuine Manx frames -made in 531 hi-tensile tubing, common road featherbeds in mild steel tubing, and Inter frames in cold drawn seamless A tubing.
And mild steel tubing for slimline type frames .
Note also that all the road-going frames came with (considerable) bracing around the steering head,
where the Manx racing frames came with none.
Some of the replica makers go either way.
Frames without bracing for road use may be a little bit of a gamble, strength wise ??
Value is in the eye of the beholder. ?
Genuine manx frames are streets ahead of anything else, as already mentioned.
