I used one of the Nukeproof adapters to fit the 27.5 wheels to my existing forks as they came with a 15mm hub.
It does the job just fine but there is a bit of play as the axle adapter is not a tight interference fit with the hub. It's probably 1-2mm play at the rim so not huge, less than a worn set of bearings, but may bug you. I've tried using a centre punch to create an interference fit which worked for a while but then wore down, if I get around to it I'll repeat that but with more gusto but it works fine without it
I have the stans no tube wheelset which have adaptors for 15mm & 9mm quick release hope this helps was running the 9mm before now using the 15 mm .
