Considering there are many jump behaviors during MTB bike riding, impact testing is critical important for MTB carbon rims.
UCI impact test standard only requires that MTB rims should pass 60J impact testing.
We set our test standard much higher than 60J, to make sure our rims are strong enough for different usage.
All ProX MTB carbon rims must pass UCI impact testing before mass production.
The detail of ProX MTB carbon rims impact testing standard can be found in below table.
