Title: Akront mudcatchers rims.
Post by: Momus on May 19, 2020, 04:36:02 pm
Does anyone know when Akront, or similar ridged aluminium rims first appeared on Spanish bikes- road or off road?

Borrani have been making them since adam was a boy and Moto Guzzi ave been using them. Not Spanish but close.  The cover of Cycle – August 1951.

Classic. Good one.  Thanks Pokey.

Someone needs to come up with a meat slicer quip for the dude in the photo.

So that makes aluminium rims legal for Pre1960 CMX

The ridged style aluminium rims  are on a lot of early Bultacos- well before 1965, my recent probing reveals.

Norton used the flanged alloy rims on the "Works" bikes during the 1930s. They painted them black to try and kid the opposition!

Interesting.

Black paint is great stuff for subterfuge.

Norton were early adopters of magnesium for bike castingss as well and as I was told by an old engineer the first to a proper 100 hp per litre (50 hp 500)output with their later Manx.

Naa Hoony, i wish I did but Im just another Guzzi tragic, The only ones to get the vee the right way round ;)
I have a stack of useless info in my head and a folder of just as useless stuff on the poota.
I cant recall the name but there was an english rim maker who was also around in the 40s or 50s who did  alloys but the good teams all had Borani.
