I recommend this product
Proscheep & easy.
These have put back into use an old set of hubs that might otherwise never been used again!
Hope quality is the best and simple to convert.

Boost rear wheel
05 Aug 2022
Hi , I’m currently trying to fit set hope pro 4 wheel rear non boost (135mm hub) to my 142mm boost frame , will this kit allow me to do this, if so will my wheel need redishing , thanks
This item is for148mm (BOOST) spacing, not 142mm. For 142mm spacing this, you need SJS part 43826.

Would this part work on hope hoops hub?
20 Dec 2020
I don't see why not, however as we have never made this conversion before with a HOOPS Hope hub we recommend you speak to hope directly prior to making this conversion as there is a chance the end caps might not be compatible. Without knowing the exact model of Hoops Hub we are unable to guarantee the success of this conversion.

Hi is the small washer to use for the front wheel?
02 Dec 2019
No, the washer sits behind the end cap. This is for rear wheel only.

Thanks - 03/12/19
Do I need to re-dish the wheel? Or does this not affect the rim at all?
23 Oct 2019
Hi there,

This part doesn't really affect the rim so you will be fine.

150mm to 148mm boost
29 Jun 2019
I need the conversion kit to swap a 150mm rear pro 4 hub to 148mm boost. Is this the right one?


unfortunately, this can only convert a Hope Pro 4 rear hub from either 135 QR or 142 x 12 into a 148 x 12 boost hub
Would I be able to use qr end cap with this to make it fit a bike with 141 spacing?
16 Jun 2019

this should be possible.
Does this come with instructions? And is this what I need to convert my 135mm pro 4 hub to 148mm ?
08 May 2019
Hi, yes instructions are included. Yes you can convert from 135 mm to 148 mm. Thanks 08/05/2019
