Lance Armstrong fans may be interested in this little piece of history: a special edition Giro Atmos helmet worn by the American on the final day of the 2005 Tour de France to celebrate what many believed at the time to be his seventh legitimate Tour victory It was designed to.

You have long since made up your mind whether you hate Armstrong for being part of what has been described as one of the most sophisticated doping programs in the history of the sport, or whether you love him for, I don't know, being dominant as a result.

British cycling enthusiasts might describe him as a "marmite." The term was coined in reference to the famous yeast extract bread advertising campaign, and indeed, the yellow and black Giro Atmos helmet design perfectly mimics Marmite's "corporate colors."

Some fans, however, have been more interested in the good deeds Armstrong has done for the cancer community during and as a result of his return to the top ranks of professional cycling after his own testicular cancer battle, and the funds subsequently raised by his Livestrong Foundation, as well as Armstrong's would point to hospital visits and messages of hope delivered directly from himself.

Armstrong, who retired after his seventh Tour win in 2005, made a comeback in 2009 because he wanted to continue his fight against cancer.

"The most important issue is to bring cancer, which is so prevalent worldwide, to a bigger stage," Armstrong told CNN at the time. 'The best way to do that is to race around the world. To race in Australia, South Africa, South America, Europe, the U.S., that's our top priority."

Whether some of that good work was then undone when he was exposed for doping irregularities is a story for another time, but he is still being talked about and reported on.

Cycling News editor Daniel Benson recently wrote this about Armstrong's coverage as part of the site's 25th anniversary this year. I recommend reading it, even if you are not sure you really want to read it, as it gives a good idea of Armstrong's polarizing nature when it comes to covering Armstrong from a media perspective.

This eBay Find also seems to be polarizing. From their comments, it seems that the Australian-based sellers have decided where they stand. 'Time to let it go,' they write in their listing, but admit that they originally purchased it as a memento."

There is no doubt that this unworn helmet is still indeed part of the memorabilia.

We will spare you the long story about the "reasonable decision" of the U.S. Anti-Doping Agency to deprive Armstrong of these seven victories. You already know how that happened. However, the helmet bears a decal celebrating the seven "victories" from 1999 to 2005.

There was already a patriotic red, white, and blue Texas Lone Star version of the helmet, but this is a very similar design, with a yellow star on a black background, the LIVESTRONG Foundation's corporate colors.

A good-looking helmet, this Giro Atmos model was great, both this first design and the second one that came later. You would have to like it a lot to pay A$900 (US$625/£500) for this helmet, though.
