I also use one of the sun ringle converters above, to be honest I quite like it and think it is more secure than qr.
I had a shit load of problems getting a conversion kit to change the front from qr to 15mm, really made me regret buying the wheels. I had the kit on order from hibike in Germany and cambria bike in the US. Neither had stock. After emailing easton, and then posting on their facebook page, easton said they would send me the conversion axle, another month later just an end cap turned up in a huge box. Thankfully by then cambria bike had got stock and sent it out, thank **** I hadn’t cancelled the order when easton said they would send one.
Easton’s aftersale service is frankly absolutely shocking, I wouldn’t touch anything with moving parts from them again. If you have a look around the internet, this unavailability of spare parts is a common theme that has been going on for years. I can understand something like that happening when a product takes off, but a company the size of easton should be able to get on top of it, and ensure the supply line is there after a while. Basically it comes down to, once they have sold you a product and have your money they don’t give a ****.
I have bought some spare spokes and the special nipples, just in case, because I don’t want to be chasing round trying to find them if/when one breaks, and I might do the same for the freewheel.
One thing other thing with them is that they go up tubeless very easy, but they also go down very easy, for some strange reason if you burp them rather than just losing a bit of air and needing topping up, they just completely lose everything. So I have ended up running higher pressures than I used to with stans flows.
