Is this the correct drive side spacer for a microspline freehub when fitted to Pro4 Boost hub?
15 Jan 2021
The diagram on the Hope website for the MS freehub shows 2 different spacers for 12mm thru-bolts, the HUB1016-04S and the HUB1016-03S.
This is the correct part you need- SJS part: 52571

Thanks, 29.01.21
Hi. Is this the correct part to use on a Pro4 Boost 148 hub? Thanks.
15 Jan 2021
Thank you for your enquiry. The end caps you require for the Pro4 Boost 148mm hub are as follows:
Drive-side - HUB471, our item 44074
Non Drive-Side - HUB463N, our item 44039
If you input the Hope code or ours into the search box it will take you straight to them.
Kind Regards. 15/01/21 JP
does this also fit the pro 2 evo x12 microspline hub?

I need to know if its 135 or 142 old you are running- as the spacers are different sizes.
