If it was only so easy then why would they sell two different versions of the same fork in 26" and 27.5".
I really don't know and need to figure this out.
Forks for larger wheels usually have more offset which will change the trail of the wheel.
If someone would adjust the mounting position of the crowns from a 29" fork it wont be the same as a true 26" fork.
If you would put a small wheel into a 29" fork it would have a very low trail and therefore bad handling (at higher speeds), which is basically the worst thing you can do for a bike capeable of speeds close to 100kmh.
Regarding X-Fusion, i have bought one of the 26" RV1 from the link posted here recently (about 380€ shipped to my door from Taiwan), and all i can say so far is that it has almost no stick-slip or stiction - even with some weight on it.
What i really like is the independent low and high speed compression settings which work MUCH better as on the latest Rockshox Charger 2 Dampers for instance. I could compare a Boxxer and Lyrik (the latest ones with debond air spring) with the X-Fusion and guess which fork i did like better
-> Don't listen to theire marketing bullshit and probably sponsored reviews and test reports from the internet!
I was also looking for a used 26" R2C2 boxxer (which are availale around 300-400USD), but now i would always take again the X-Fusion RV1 if you could find it for the same price.
The only downside is that it comes with a very soft spring and replacement springs cost around 60USD (i bought the extra firm spring).
