[Closed] DT240 RS Predictive steering - can it be converted to normal boost?

No, that hub only works on Rockshox Predictive Steering forks (RS-1, Pike, Revelation...).
The endcaps cannot be swapped like in their regular hubs (

).

No, afraid not, it's a completely unique hub, doesnt share any components with a standard Boost hub.

Well I think it's a mix of the above :0)
Any rockshox fork that is torque cap compatible (any boost rockshox I believe) will allow the predictive steering hubs to fit but you will still need to shim the rotor by 2mm due to the different brake mount position on the rs1
Note. It is an overbuilt hub so a fair bit heavier than the standard hub.

Hmm possibly not worth a punt then.

How do I know if my rs forks are comparable? They are 2019 sids

Bit of a thread hijack, but all those DT Swiss videos show the end caps being removed in a vice. How do you remove them if you don't have access to a vice...?

pliers*, maybe even just strong fingers

*with a bit of old inner tube over the jaws so you don't scratch the pretty finish - if you care

The ps hubs are quite porky if weight is part of the consideration.
A few ways to check. Rockshox used to put torque compatible stickers at the bottom of the lowers, I think all boost rockshox forks are torque compatible, you can visually check the axle cut outs on the lowers (a large machined space for 30mm end caps rather than the standard 15mm)
Or you could just pop the ps hub in your sid (remember that you will still need to space out the rotor by 2mm for everything to line up)

If i'm not using the vice for DT endcaps, i use a ball end of a 10mm hex key, insert just enough to the edge of the cap, then lever off, they tend to pop off easily like that, they're a nightmare to try and use pliers or the likes, as you need a lot more force taking them out level, rather than putting something in then levering them at an angle.

Unior hub genies work very well for end cap pulling without marking the outside.
