Titanium hinge pins for stampede? keep breaking caster blocks

not possible. Also, stock hinge pins are too weak. Surrounding them with stronger parts won't help since the pins aren't captured. They're in simple shear. I strongly suggest you move up to 3mm pins whatever route you take.

I've been there, and I suggest you return the blocks to Mike if you want the RPM hubs , and pick up these blocks up instead...

FLM has nice stuff but I am at a loss as to why they chose nitro style hubs for the pede. Not worth the headache to me to convert everythign to nitro.
