DT Swiss 350 rear hub conversion

I’m currently running a DT Swiss 350 rear hub with a 11-speed Shimano free hub and want to change to a 11-speed SRAM free hub to gain the 10T for when I’m pedalling to the trails.  Is it simply a case of buying a DT 350 SRAM rear hub or not?  I ask as an on-line retailer who I asked said that their product would fit but was for 12-speed.  Now I always thought that to convert to 12-speed from 11-speed simply meant buying a new rear derailleur, shifter and cassette, not a new free hub as well.  Happy to be proved wrong.  As my 11-speed system is working fine I see no need to leap to 12-speed

Xd driver is xd driver

That’s all you need the xd driver freehub for the dt 350

Make sure you buy one with the XD end cap as the don’t always come together.

Thanks both, that is what I thought

It’s the same as the XD freehub for the old 240, which might make it easier to track one down (but NOT the same as the newer DT240EXP)

Incidentally if you don’t get the right endcap- used freehubs often won’t come with it- you can easily modify your current one, it’s just the “brim” of the hat is a little too large. Seconds in a lathe but easy enough with a file.

This should be what you are looking for (assuming you have 12mm thru-axle rear)
