Speedring needed?!?

hi all,

I have a just bought a GTX AT, and i was wondering something.

I have just cleaned the tires and noticed that there is no Speedring on all of the tires, this came like this “out of the box”.

Is it still needed? As the wheels spin good and freely.

See the picture.

Thanks!

 

It might have changed, but yes you should have a minimum of 3 speedring/washer per traction wheel and 2 on the free running ones.

On the back: axis => silver washer => gear => black washer => wheel => black washer => nut.

At the front: axis => black washer => wheel => black washer => nut.

I'm ignoring bearings and spacers

Same thing on a AT wheels video:

 

Thanks for your reply. I am still unsertain if they are needed, some people say they do and some dont. Think i am still going to ise them

 

Hi. Your strut appears to be a later version that has been adjusted. You will not need a large speed ring on the inside of the drive gear bearing.
If you have bearings with built in spacers, you shouldn't need one between the gear and wheel either.
However, due to manufacturing tolerances, the best way to ensure the best bearing adjustment is to install the drive gear and wheel without the belt. Tighten the nut like normal (not over tight) and check the free spin of the assembly. If it seems restricted, add a speed ring between the wheel and gear and check again. Once the wheel and gear/bearing preload right, install it all with the belt.

Hope this helps,
Nick
