I've been off my fat-bike for a month while it's been in for service. I ditched my carbon rims in favor of some DT Swiss aluminum. I needed something more durable, something that would be a lot less likely to leave me stranded out on the trails in sub zero weather. I've gone tubeless with the new setup.
I also had my RockShox front suspension overhauled so it will function in the bone-chilling temps that will soon be the norm.
