I have a 2021 stumpjumper Evo, not exactly a rare bike.
I'm wanting to lace the rear hub - a DT Swiss 2
360, jbend branded as Roval - to a DT Swiss EX 471 rim. (29er 28h)

I absolutely cannot find this hub on any calculator. I reached out to DT Swiss and even gave them the serial number and they apparently didn't have enough information to even get me the spoke length and tension i need.

I think this hub is the same body as the 370, but obviously I need to be sure.

Does anyone know anything?

Any reason you wouldn't measure it yourself?

The ERD on your new DT Swiss rim is 600. Roval doesn't publish the ERD but the rim depth is 22 and the rim diameter is 622 so that should mean the ERD is 600. If you are trying to swap rims it should work and you could reuse your spokes if not damaged and get some new 14mm nipples.


Got this from Roval site for traverse alloy wheels.

RIM DEPTH
22mm depth

SPOKE
SPOKE PATTERN

He is looking to change from a Roval rim, to a DT Swiss. The issue is he needs hub measurements to calculate new spoke lengths.

I updated my reply with the ERD info. I recently went through this trying to replace a very dented roval rim wit DT Swiss.

Ah! Got ya. So you also have hub measurement and you are holding out on us? Razz

Just teasing, I appreciate your effort.

Still, I would measure everything myself. Quite often, even published numbers are wrong. I actually believe even DT's published ERD numbers are sub-optimal, for their Squorx nipples. The account for this to some degree in their rounding algorithms, but that doesn't always work perfectly - or at all, if you are using a different calculator.

Thanks folks. Ended up taking it to a shop with an experienced wheelbuilder and he measured everything by hand with the new rim and put it in the calculator. It's crazy to me that that hub isn't programmed in to anything already.
