Oh the shame.
My commuter / winter bike was put away wet and unloved at the beginning of the year.
On return from an aborted French ski trip, work was from home.
Then furlough.
Only just got round to digging it out.
In need of major work. The cranks / BB are seized almost solid.
Only I can't get the HT-2 crankset out.
The NDS arm comes off fine, but the spindle is utterly seized to the bearings and could not be driven out.
Made some progress by unscrewing the NDS BB cup from the frame, pressing it off the spindle, but the forces involved were in danger of stripping the frame.
In the end, it was destructively removed with an angle grinder, cutting the partially-unscrewed BB cup and hollow spindle off.
The remains of the spindle was then driven out through the Drive-side bearing, taking the bearing with it, out of the cup.
Destroyed: 1 x old Ultegra Triple crankset, 1 x Hope BB.
The frame is fine.
Bah.
