Thinking of treating myself to a new frame, swapping over all the upgraded bits from my current frame.

I currently have hope 20five wheels with the RS4 hub fitted for QR (early disc adaptor for the road).

The frame I’m thinking about has 142mm bolt thru – I’ve looked but I’m still not 100% sure.

Can I get end caps to adjust the fitment as I would with pro4 etc?

Yes you can, but be aware the RS4 ones are not the same as Pro4

Part numbers are listed on here 142 is X12 iirc

Excellent – thanks for that.

I know the RS4 is different and I dunno how I got myself so confused on adaptors.

/Tips hat.

Don’t beat yourself up over it, Hope stuff can be infuriatingly confusing at times, I’ve just spent 20 minutes in my LBS trying to work out which RX4 caliper they needed to order for me (I think we got there in the end, will find out in a few weeks when it turns up!)
