Last week, professional Austrian cyclist Markus Stöckl set the speed world record of 104.14 miles per hour on a commercial downhill mountain bike.

“It’s a standard mountain bike, so there’s no part on the bike that you cannot buy,”Stöckl told Dirt afterwards. Sure, it’s a high-end bike with the best parts, but you can buy any part. Nothing has been specially made.”

He took his Mondraker Summum from zero to 104.14 miles per hour in eleven seconds, down a 45-degree-angled volcano in Chile. Stöckl had a spandex suit specially designed for this record attempt. He has been setting speed records since the late 1990s.

However, this isn’t the fastest speed reached by a mountain bike. Eric Barone has hit 138.8 miles per hour but on a specially designed bike.
