I don't know how long the Helix manual has been available on the Helix customer portal, but I just found it. Since people frequently mention the helical hinges wearing out due to dirt getting in etc. I'll post the section about how they are designed to be maintenance free:
HELICAL HINGES
DO NOT LUBRICATE - The helical hinges are designed for use in dirty environments and do not require lubrication. Road oils and grease will not affect their performance.
FORK AND STEERER LOCKING DEVICES
DO NOT LUBRICATE - The fork and steerer locks are designed to never need adjustment and require no lubrication for the lifetime of their use. Road oils and grease will not affect their performance.
It will be interesting to see if this is true.
