DT240 End Cap Conundrum

[kppolich]

Here is what I have gathered and shared with DT Swiss. I already ordered a set of replacement end caps with hopes of getting the right length DS end cap.
Result was: This is actually a 12x142 MTB hub and those come with different end caps than the 'Road' 12x142. Solution was to order the road 11s end caps.
Let me know your thoughts Paceline.

Main point: the DS end cap (short one) on the left is from a DT240 hub. It is obviously shorter than the one on the right and is causing my issues.



Hi Team,

I purchased a set of Enve CX Tubulars that came with DT240 hubs (12x100 and 12x142). However, when I installed them on my 2019 Trek Crokett (12x100, 12x142) I noticed that the rear spacing on the hubs wasn't 12x142. In the fourth picture you can see the DS end cap on left is about 3mm shorter than the DS end cap on the right from my Roval CL50 (DT350 hubs).

When I had the DT240 hub installed the 11T cog would bind against the frame. When i installed my roval CL50 rear wheel there was room. I swapped the DS end caps and the DT240 hub worked as expected.

Whats going on with the original DT240 end cap? Is it really 12x142? These are the stock build from Enve.
