Title: ZRace Microspline freehub won’t spin
Post by: Joselu on March 10, 2025, 08:05:15 AM

Heya! I have a pair of DT Swiss P1600 wheels that I want to convert from HG to Microspline. So, I bought this MS freehub: https://es.aliexpress.com/item/1005005310126883.html (https://es.aliexpress.com/item/1005005310126883.html)

It seems the Quick Release end cap is preventing the wheel from spinning, as it doesn’t seat properly on the hub bearing. Do you have any idea how I can fix this?

If it does not spin it means there is too much friction. I assume some spacer is missing or some spacer are too big.
Did you measure the end-to-end measurement? is 142/148 mm exact?

Is the endcap correct?
Are the bearing perfectly seated?
Is there any interference with seals?
