Re: 44 to 36 tooth sprocket swap HI All,
Concerning the use of the rubber spacers on the 9 hole mounts , I have to agree with Norman....Best to use the rubber spacers to sandwich the spokes.....rather than steel on steel as suggested.
In theory, one may be able to get away with steel on steel for awhile IF there is no movement between the two pieces (in this case the steel of the 9 hole mount or sprocket and the spokes themselves)....which could result in a cutting action between the 2 pieces and result in damaged parts / possible accidents.
The hub obviously has the spokes passing through them which is steel on steel or steel on aluminum depending on hub material, BUT since there is no real relative motion between the parts that is why they last....
Lastly, since the rubber "conforms" to engulf the spokes, they allow for more surface area to transmit the engine torque to the spokes rather than just the "tops and backs" where the metal touches the actual spokes should the rubber parts be omitted.
That's my take on the rubber or no rubber situation.
Hope this helps.
