went t0 the hardware store and purchased a 6mm plastic knob ($4.60 US). here it is next to the stock bolt:
clamped the new knob in my bicycle repair vice to cut it:
here it is cut down:
no more torx required for removal!
After getting underneath the seat a few times the last couple of days for various reasons. I've decided to take your lead and replace with a knob myself. So, the search begins to see if the local hardware stores have that item. Oh, and I need a new hacksaw too. Always need new tools!anti-seize...i put that $h!t on everything!
ok, thanks U22, that was a no brainer. You rock.
