For the clamps it’s .58” wall thickness, 1 1/4” od for the steerer clamp and 1 3/8” od for handlebar clamp I think.
I’d been using the 1 1/4” x 0.58” for the extension tube too but have been trying lighter weight stuff for the extension tubes recently, off cuts of 1mm wall thickness stuff I’d got from Ceeway for framebuilding stuff.
