If you've got conventional quick releases on your DT Swiss 240s equipped bike and want more security and stiffness, these are the kits you need to upgrade to RWS Thru-Bolts. The advantage of the DT Swiss RWS Thru-Bolt is that it can be tightened more than your average skewer and won't flex or stretch when it is under a heavy load, like braking on rough downhills, or during hard cornering.

The DT Swiss QR to Thru-Bolt Conversion Kit is available for front and rear 240s hubs. Both front and rear kits contain the appropriate end caps to make the switch to use the 9mm or 10mm RWS Thru-Bolts respectively. Please note: these kits do NOT include the RWS Thru-Bolts. You'll need to purchase those separately.

Note also: The front hub conversion is specific to the 6-bolt 240s hub and the rear hub conversion also works with XRC 1350, XR / X, XM / M and EXC / EX / E wheels.

is this kit to convert the front hub to a 20mm thru ?

will it work to convert a 15mm front to a 20mm front?


Pretty sure that this is just to convert a 9mm to a 10mm thru-axle. If you wanted to swap out your 15mm to a 20mm, it's a different part but is the same style. I've done it with my DT440 hub, and all you have to do is buy the new cones. Takes like 2 seconds to swap em out too. This is what you need:

Easy swap and works on 350 hubs as well.

  • Familiarity: I've used it once or twice and have initial impressions

This was about as easy as it gets to change out. I went to a 135 x 10 on the back and this change took 5 mins to do. Just pop off the caps that are on there there now put in the new ones. (have to take off the cassette)

Also I have 350 hubs and they work on them just fine
