Welded Cush Drive?!

(1/3) > >>

Raygun:
I have myself some beautiful looking Lester Mag wheels- however on inspection the rear appears to have the cush rubbers removed and the hub welded to the sprocket carrier?

Does anyone know why someone might of done this? It can't be an easy thing to weld so hardly by accident, I imagine. This also raises some issues with replacing my rear wheel bearings...

Best,
R

McCabe-Thiele (Ted):
Could the wheel have been made that way - like you say the welding ain't easy?

K2-K6:
A bit strange, and certainly for a road bike, on which you'd expect to have a cush.

Racing I could see the potential to modify as some would use no or very very litte cush effect to give direct response to input. But it would normally be at the expense of chain and sprocket life which they'd probably be willing to accept.

There's one in the primary drive to catch engine vibrations and prevent onward travel into further transmission.  Then this one that allows the next stage to run vibrations separate from being directly constrained by the tire on the road. Technically it'll work as the peripheral weld should easily take the torque,  but at the expense of component lifing and added harshness to the rider.

That's some really great information, thank you for sharing. It seems like, in that case, using this wheel won't kill my transmission whilst I potentially seek out some new wheels.

I'll share some photos tomorrow when I'm working on the bike. The welds are reasonably neat so in response to Ted: I had originally thought this is how the wheels came, until my local tyre shop didn't want to fit tyres to these wheels in the first place.

I think i have a lester rear in my stash, i will look it out if you wish and check it over. Pics of yours would be good to compare to.
As its a lone wheel dontwant a fortune but dont expect it to be free and carriage would be not cheap
