If I remember correctly the ABS bearings spacing is different than on the non ABS bearings? Anyone know if this is correct?

Thanks

 

I understand the bearings are completely different and have a sensor magnet in them.

 

I have done a little more checking and it appears that the ABS bearings are not as wide as the non ABS and a spacer can be used on the ABS bearings and your stock axle spacers can then be used.

 

I'm running a set of ABS wheels on a non ABS bike, don't remember the spacer sizes, but it was a lot easier & cheaper to do, because I had the spacers already.

 

ABS bearings are wider than the non abs bearings. ABS bikes do not have a spacer on the left side, but rather have the abs pickup.
