I don't think / know any rider is clean, and a tattoo, poor performance and books does not make them so. The British junior busted in 2015/16 (who raced my kid) had similar results to Gaimon and was always in the back.

Horner was tested by USADA some 129 times to Gaimon's 38. https://www.usada.org/testing/result...-test-history/ more than any other USA cyclist. Horner has a blood passport - you can see what that involves on the UCI site. Gaimon has a tattoo and pretty low WT rankings to show he was not doping. Horner is as clean as the system can certify, and he jumped through the hoops more than anyone else. He deserves that title as much as anyone. Any and every GT winner gets to be accused of doping. It is often true, but that is all the hard stuff I know on Horner. If Horner had Gaimon's performance nobody would be saying anything. If Gaimon had Horner's performance, well, that tattoo would not save him.

That Gaimon was a WT pro as Horner was does not mean he somehow knows something. Gaimon and Horner were not WT teammates and in different circles and times. They would be very unlikely to share information. Sure - win a GT and everyone knows someone who knows something. It was likely Russia.

Gaimon has not disclosed really much more than Horner's arrogance about why he thinks Horner got away with stuff. If Gaimon knows something - he should stop being a wimp and disclose it, otherwise just he should just talk about himself in interviews and not those he won't produce any evidence against.
