Some kids have way too short a memory to see the exquisite irony in this post.
Never had a product recall.
Sure we had way more QC issues with the early batches of Wombolts and even Twombolts than I would have liked but there was nothing inherently flawed in the design which is backed up by the fact that we still make cranks using this design and they do have a very good reputation for strength now.
On the other hand, putting big sharp cornered slits down an axle loaded in combined bending and torsion was to my mind pretty obviously about as terrible a design as you could imagine... it's not like a few of these "might" break eventually, it was inevitable that they all would if actually ridden.
