Training wheel, innit?

If anything, aero is even more important to sprinters as they are the ones who go fastest; at 70km/h, a sprinter has nearly 60% more drag power per CdA than a pursuiter doing 60km/h

Its not a training setup. The bike is Olga Panarina's from Belarus.
Here she is in the bronze final in the 2011 World cup sprint final with that wheel. http://news.bbcimg.co.uk/media/images/51855000/jpg/_51855701_pendleton_ap.jpg

I even believe she was one of the last to change to a sprint specific helmet. I don't think they have a lot of government support in Belarus so that might be the reason.

Her trainer is a big fan of leather too :)
