Thanks for the heads-up!

Checked with lbs this morning -- they have 'the parts' from Specialized, and will do the recall for me ('19 Sirrus X Comp, still with stock cranks) Monday. Apparently, an unnecessary spacer was factory-installed on the left (non-drive side) crank, which therefore will, eventually, fail w/o warning.

Hoping 'the parts' are an Apex 1x crank, but I don't really care as the crankset will, eventually, be significantly upgraded.
