Interesting what is and isn't there.
Rear wheel:
Vincenzo Nibali, 2010
Fabio Aru, 2015
Alberto Contador, 2012
Juan José Cobo, 2011 - disqualified, so strange to see it here
Front wheel:
Chris Froome, 2017
Chris Froome, 2011 - both 2011 jerseys? Seems odd to acknowledge both
Simon Yates, 2018
Primož Roglič, one of 2019-21, can't quite tell
Top tube:
Roberto Heras, 2004
Roberto Heras, 2000
Seat tube:
Alejandro Valverde, 2009
Roberto Heras, 2005 - now the official winner again
Stays:
Tony Rominger, either 1992 or 1993, can't quite tell
Laurent Jalabert, 1995 (could be Melcior Mauri 1991 or Alex Zülle 1996-7, but looks like Jalabert's)
Down tube: Denis Menchov, 2007
Pedals: Aitor González, 2002
Forks: Jan Ullrich, 1999
Handlebars: Alberto Contador, 2008
Seat: Roberto Heras, 2003
Surface:
Tony Rominger, 1995, Abraham Olano 1998, Álvaro Pino 1986, Alberto Contador 2014
Missing in timeframe:
Luís Alberto Herrera 1987
Sean Kelly 1988
Pedro Delgado 1989
Marco Giovannetti 1990
(possibly) Melcior Mauri 1991, Laurent Jalabert 1995, Alex Zülle 1996-7 (I believe the ONCE jersey there is Jalabert's)
Ángel Casero 2001
*Denis Menchov 2005 (Froome and Cobo are both there...)
Aleksandr Vinokourov 2006 (the gold Astana kit could also be his, but it has a sponsor that references 2008 on it so I assume it's Contador's)
Chris Horner 2013
Nairo Quintana 2016
The latter two could be there though, there is a red jersey which is obscured in the bottom left where you can just see the edge of the sponsor square, it's very dark in colour but I can't tell if it's the black of Radioshack (which I think more likely) or the navy blue of Movistar.
