Nothing at the minute, a couple months ago I bought a bike that had 15mm forks with SLX wheels, but I wanted to use my Hope wheels instead, which was easy as you can get Hope adaptors anywhere. I had the SLX wheels and QR forks left over as spare, and after some googling I found loads of people whingeing about how they couldn't adapt 15mm shimano hubs to QR, and only one person saying they actually did it with the Mavic adaptors. I have no idea why Shimano don't make some, they work fine
I almost bought a 29er MT55 front wheel last weekend to replace a wheel on my pompetamine, but decided to get a new rim and rebuild the wheel instead. If I did go for the wheel I would have gone for the 15mm with Mavic adaptors again, just in case
