The separate support and steerer is a trampoline frame pole, I used whatever I found and was trying to not get involved in cutting the frame as I'm a joiner not a welder, would make it different next time as had a few head scratch moments, total cost will be around £200 so all round happy
Love it. Like the exposed steerer with separate support. Suppose its made it easier to maintain the integrity and strength of the main beam.
Great work. The joyous moment of going for your first test spin and it actually working is still fresh in my memory.
