Production units will be even further reinforced and the wall thicknesses have grown as the Grit in that video seems like it was a first gen based on the HTA.
Release date should be mid-April. We will only be selling completes initially but we're sure you'll be able to find parts available from other riders who customize theirs. It's possible that we'll have parts for replacements but unsure at this point.
New wheels (and full metal cores at that!) just arrived today and we will send them out next week for testing. We may need one more round but these seem pretty close to what we were looking for.
