Flanged Rims

My 72 has flanged mudcatcher Akronts on her. How much of a weight saving is there in converting to modern rims?
The bike is going to be a racer

Not significant enough to bother changing unless you run some old time tracks with a high % of loam content. Then the only difference in weight is the weight of the mud the rims retain.

The Akronts are much more rigid than DID rims. If I were to replace them, I would use Sun. If you want to be period correct, keep the Akronts until they get egged.

Thanks for that

I never rode a husky with those rims. I think they are more rigid and dirt bike stuff by now has the rims and spokes and spoke angles to get a certain amount of flex. Probably those rims are more rigid than really ideal is my guess. Now about the weight, perhaps it is how far out of balance they can get. Somehow I seem to recall hearing something to that effect, not the weight directly. Are there wheels from a bit different year that you could use instead? Or perhaps just the rims, I know on these forums it is common to state what can be purchaced new.

Have a word with Rod Spry in Manchester. He got me some NOS Akront rims for my 78 Auto. Very reasonable price too. They were the normal type, not the mud catchers that weigh a ton when they fill with mud and stones.

Luckily it doesn't rain in Wales, so there's no chance of that

Of course you are correct I keep telling myself that wasn't rain at one of Robbie Griffiths meetings many years ago. It took me 2 weeks to clean the congealed sunshine off the old BSA :-)
