Thunderbolt

[@keir108]

Yeah I've just started getting cracks developing on the left side crankarm next to the chairing bosset after 18 years of riding my original wombolts so it look like it's time to see if I can find a second hand pair of thunderbolts on tea bay!

[@TsukuyomiPlayz]

One pair is kink pillar.. one are fly dolmens.. other are primo hollowbites. Idk what the raw ones are

[@LeonardoDBarbosaG]

The machine is testing the fatigue life of the cranks. It is imitating the stress put on the cranks every time you jump and land. This is done by cycling the object in this case cranks until they fail. The more cycles the object sustains, the stronger they are. Results are shown 0:50 seconds in.

[@dillonleuschen9844]
