DT Swiss 240 hub end cap compatibility?

[ridethecliche]

Hi!

I bought 2 sets of wheels recently with dt Swiss 240 hubs. They're both currently set up as 12TA in the front but my bike is currently 15TA.

I bought a set of adapters but they look different and I think then might be for the 350 hubs. Are they not interchangeable? Just wanted to make sure so I don't break these nice wheels!

Thanks!

No way you're going to break the wheels, the end caps just pop off regardless of whether they're 240 or 350 hubs.

I mean if I put in caps that aren't compatible!

Still not going to do any harm. The circumference of the caps is the same regardless of hub, the difference is the length, QR vs thru, etc.

The 350 and 240 share rear endcaps but the front are different

They're are 17mm and 18mm axle versions of the 240 depending on whether it was sold aftermarket or in a wheel

Guessing there's a difference between the 17 & 18 in terms of parts. How do I tell the difference?

I might have just bought a few sets of the wrong thing Oops.

Thank you! Will do.

Didn't realize it would take so much to get these two wheelset going!

Are there DT Swiss 240 front hubs that are not compatible with 15mm TA's?

I'm still waiting to get DT Swiss to answer my email appropriately. I sent them the part number and tried to explain an interchange that I'd done and they just didn't respond saying that I didn't give them the info they'd asked for even though it was right there.

Next time... I'd just leave any extra info out. This has been frustrating.

I'm concerned that two sets of wheels I bought are built with DT Swiss 240 hubs that will not accept a 15mm TA...
The stock fork my frame came with has an AL steerer but also 12mm TA's, but it's much heavier than the fork that I kept from the warrantied frame. Frame was cracked, fork was fine. So I just reused the fork because it was nicer and lighter.

This has been a headache though. I don't want to have to use the fork that was part of the frameset because it'll require me to swap headsets and get an adapter for the front caliper. I guess I might be shopping for a new fork before I thought I would... Or I could just sell this bike and start over.

I hope I'm totally wrong about this. It would be pretty frustrating if their hubs were built without any backward compatibility especially since the compatibility or lack thereof isn't obvious at all.

What is the hub spacing?
12x100 and you want 15x100?

What is your fork spacing?
Asking to make sure it isn't boost

Finally, is your front DT240 hub Centerlock or 6-bolt?

I ask because this looks like the correct part and they even give you things to check to confirm in the description.

That's what I think I need but looking through the identification stuff on dt Swiss' website the only hub that matches mine shows compatibility for qr and 12mm TA. The other ones show 15 as an option.

Will update when dt Swiss responds!

Probably not relevant here but what it’s worth:

the only Dt 240 disc hub that I have come across that cannot be converted to 15mm thru are from before 2008, or even 2006? But a Canadian company made axle for that purpose. Am running these on my single speed MTB.

this. take a pic of your hub's serial number or write them in the email and sent to DT Swiss. they will tell what end caps to order or if they are not compatible.

I had 3 sets of wheels with DT hubs that needed to be changed to 12TA. They were all 15TA front, QR rear. The DT350 wheels were easy. The others I could change the rears but the front DT240s were not changeable to 12TA per DT Swiss. So I ordered one of those CNC'd 15 to 12 adaptors from Amazon and had a friend who has access to a metal lathe turn down the 15TA adapters so they would fit my 12TA fork.

Heard back from DT Swiss this morning. Looks like my concern was warranted.

You have the newer 240 road hub which is specific to 12mm and QR compatibility so unfortunately those two hubs will not be able to convert to 15x100mm. The internal axle used inside of the hub has a 12mm ID so a 15mm thru axle simply wont go through the hub.

Well sheet.

For reference, this is the serial number on the hub.
P2142297 409 10024734

So for everyone this may matter to at all... The newer dt Swiss road hubs will not convert to 15mm TAs. You can tell if you have that one by looking at the hub to spoke interface. I'll try to take some pictures to update this thread.

Welp. Sheet.

Which fork is it? There's a few forks that can convert back and forth between 15 and 12mm by changing the machined inserts on the fork.
