This shirt is to commemorate Rigoberto "Mick Jagger" Uran's Stage 9 win in the 2017 Tour de France. As you may know, he had a mechanical and was forced to ride in his 53-11 gear, hence the logo, to a photofinish win!
The T shirt is a poly/cotton blend and it is semi fit. It is not cheap cotton shirts that feel uncomfortable. Sizing is accurate with US sizing.
