Unlikely. Is it shorter or longer? The thread sticks out the other side on my Tripster a couple of mm already anyway and if it's simply more thread on the end, it'll still stop turning when it's tight, there might just be a little more thread inside the hub.
Interesting. I'd not seen those before (and I had looked).

They look like what I have on the Mason.
It doesn't say the front is for the Tripster but I assume it will work.
