Can't you just swap end caps and have either one? If not, I used one of those adapters once. It was fine.

 

I saw something like this:

It is made by DT Swiss so that should be good. Would I also need special end caps? This is my first build so I am unsure of what I need the end caps for.
Also wondering if it would not be better to let the builder make a 9x100 wheel since that is what the fork is made for. I.e. how good these adapters are?

 

I'd just go with the appropriate end capped 350 hub, then you can swap end caps in the future if you need to.

 

So you mean to get a 15x100 hub with 9x100 end caps pressed on it? And then remove the end caps if I ever change forks?
Sorry, just reading up on end caps now. The wheel builder didn't mention those as a possibility but that seems better than using an adapter indeed. If we can find the right end caps.

 

This might be useful (the chart, specifically):

Thanks, I found a similar sheet from DT Swiss here:

I'll ask the wheel builder if he can find some compatible end caps - they don't seem easy to come by... Annoying.

Are the end caps a better solution to the adapters? He recommended me to go for 15x100 front hub with adapter instead of 9x100 hub. Is that sound advice? I wonder if there are downsides to the adapter if I can't find the end caps in the end.

 

this is a strange discussion.

it's so incredibly easy to swap end caps for hubs that use them (a great many of the most popular ones) that I don't understand why this is even a question. I guess the adapter will work fine, too, but it also seems weird to me that DT Swiss would offer such a thing for hubs that use end caps.

 

It's really not that strange, especially if you haven't been through the shenanigans before with convertible hubs, etc.

I just went thru some similar thought process on my Surly ECR. It has a similarly limiting 9mm fork. Strangely, I actually ended up w/ a Surly Wednesday fork to solve my issues (same geometry as the stock fork, but I can now run my already built fat bike wheels on the ECR)...

 

Yeah, you just have to go through it once, I suppose. Why did you buy a new fork instead of converting your hub with an adapter or end caps?

Indeed it was strange how the bike shop didn't propose changing the end caps instead of getting the adapter. I guess I'll ask and hope they can get some.

I guess either would be better than getting the 9x100 hub.

 

My situation is weird...I have many 15x150 wheelsets, so the new (actually used and cheap) fork allows me to use those on my ECR without changing the geometry. Adapters wouldn't help in my case. And, this way, I don't need to build yet another bike specific wheel (I have many bikes and way too many wheels).

In your case, just getting the thru-axle hub with end caps seems like the most logical path...

 

deleted, didn't make sense.
