andersonkaren+FollowJack Thompson’s 2-Speed TdF Throwback!Ultra legend Jack Thompson is back at it, folks! This time, he’s taking on the original 1903 Tour de France route—yep, the brutal six-day, 2428km beast—on a custom two-speed Specialized Roubaix SL8. The real kicker? He’s going full retro, self-supported, and rocking just two gears (48x16 and 35x16). Will Jack’s old-school setup conquer the climbs and flats, or will the mountains bite back? Let’s hear your thoughts on this wild challenge! #JackThompson #TourDeFrance #UltraCycling #Sports00Share
