i found a flat spot on my rear wheel (DT EX1750) These exact rims arent sold aftermarket are they??
Cant seem to find any.
They will be hard to get after market. Even from overseas.
The closest I got was at my old LBS before it closed down.
We where on good terms and one of the dudes managed to order one from DT Swiss by telling them it was a warranty job.
Ya its a ex5.1 (ex500) rim. The hard part is getting them in white...
There is other colours as well such as green and blue. I know some Giant Reign Xs have them as stock wheels.
Sure they will be even harder to get new tho.
To answer the OPs question about the axle sizes.
The hubs are 240s. A high-end hub. And they can be converted every which way.

They do come in a 150/12mm version. And there is a 150/12mm conversion kit.
It doesnt say the kit is for the 240s, but i just made my Ex1750s into a 12mm axle.... and it says i cant do that (340 only). I think the info is a little off.
(says the kit is for a 340 hub....same sizes inside hub)
Also worth thinking about is the DT Swiss Star Ratchet upgrade, from 18t to 36t. Makes a huge difference.
For about 30 bucks its totally worth it. Very easy to service them at home as well.

E2200 has double butted spokes.
EX1750 has Aerolite spokes.
If you wana run them hard DH and i suggest maybe changing the spokes. The stock ones are thin (flat) and not as strong as others.
That been said i can take mine DHing, 3m drops, 8m jumps and they are still straight.
Guess this helps them become so light, 1750gs.
