But in October 2021 I found use for it. In 2019 and 2021 I had had two knee surgeries, solving my year-long problems with my knock-knees once and for all by replacing my knees with two prosthesises. And while I temporarily was unable to run with these prosthesises I could try to remain fit on the standing bike in my gym. And found out that my Frank Shorter singlet was quite good as bikewear.
