Test results: The best frames under test load

Risks of lightweight design
Those who regularly push their bikes to the limit may have already experienced a fractured or cracked component. This is usually caused by construction, manufacturing, or material defects that can lead to micro-cracks, even when only subject to low but repeated stress loads. Continued exposure increases the size of these minute cracks, until the remaining cross-section of the supporting structure suddenly gives away.

Brittle materials, especially some  carbon fibre designs, can show complete fracture by one single overload. If it happens with a load bearing component such as the frame, this often results in serious accidents.

Remedy: frame tests
With a range of fatigue tests the damage a frame incurs in the course of the bicycle’s lifetime is simulated in time-lapse. This is done by repeatedly applying precisely defined forces. To pass this test for a particular performance level, the frame must withstand the specified test forces 100,000 times without fracturing or showing cracks.

In addition to these tests, the EFBe TRI TEST includes additional maximum load and overload tests. Here the frame must demonstrate that it can also withstand high and peak single loads. Altogether each frame must pass seven separate tests to earn its place in our database
