BOS are now serviced by Surf Sales. I have exchanged e-mails with their service technician and they are all set up and ready to go. He was really helpful when I asked some questions about setup.
JTech also service BOS, as do Mad Elk cycles in Ireland, all of which I contacted prior to purchasing my bike.
I have air shocks both front and rear on my Morewood and can thoroughly recommend them. However, they are not like other suspension units in that they are setup from the factory and need very little fettling. Also, the car park test is useless with BOS as they almost feel as if they aren’t working properly, but when you get them on the trail…. 😯
In short: Don’t be put off by the BOS suspension.
