Hi guys,

I am installing a new front hub on my P150x (I stripped one of the threads on the old one) but I am finding that the diameter of that inner gear for speedo is different from the new hub vs old. The challenge is that I canít get new hub on and I think I messed up the seal that keeps all that grease in place.

Anyone know how to ensure to order right part from SIP?

Thanks,

V

Here is size of new hub:

Old hub seems to be 4mm shorter in diameter:

Looks like you have the old, 16mm hub and the one youíve got is the newer 20mm one. Measure the diameter of the axle, just to be sure. Youíll have to return it and get the correct one...

Yep. Didn't realize there are two sizes. I have the old 16mm one. Thanks Safis!
