Our frames have undergone rigorous road and laboratory testing including the latest international safety standard - BS / EN / ISO 4210 where the frame is subjected to the following tests:
It is an acceptable practice to provide a separate frame for each test in order to attain the standard, however Silva have chosen to put one frame through all 5 tests, ensuring that our frames are capable of withstanding the most rigorous use.
For example, not only did our Celero frame achieve 100% success, it over doubled the required standards for Frame fatigue with pedaling forces – the most of the fatigue tests.
Frames are required to reach 100,000 cycles on each fatigue test to pass the entire testing process.
Our Celero frame achieved over 220,000 cycles - that's well over twice as strong as required...!
Every piece of wood is unique, and this adds to the beauty of our bikes. Whilst every care is taken to select the best section of timber, it is not the same as selecting a piece of metal from the shelf which has been created under controlled conditions.
We therefore over engineer our bikes to take account of nature's variables, however it must be acknowledged that we are working with a natural material and therefore the integrity of each frame cannot be guaranteed.
