Yes. The sheer strength in this tube is no doubt up to the task but the bending load might overwhelm it. Sleeving with steel might work but I think the plastic deformation load will be different between materials and so one might be bending while the other is breaking...I need an engineer!
Thickness measures at 2.15mm at the ends and has an internal shoulder where it thickens to 3.3mm it is aluminum and no doubt a high load piece as it is designed to take big air impacts from downhill mountain biking.
My trike has a wide wheel base and is going to incorporate a small sail so the...
Yes, the black tube which is a downhill mountain bike axel is the axel. I was also concerned about its hollowness and was going to sleeve it with aluminum or steel. The quick release will go through the whole assembly and in to a threaded insert in the elbow.
This is my first build but not my first rodeo. I have been concerned with the strength of my steering wheel attachments, I have opted for 20 mm downhill hubs and axels. See my pictures please. Should I be concerned with folding up the steering tubes?
Any other thoughts?
