The start of this test was not how I planned it. On the first ride I damaged my THM Clavicula crank and could not ride my MTB for 2 weeks. I changed to another crankset for the time being. The THM crankset is now under repair.

Did a couple of rides on the MTB, total of about 150km. All in dry conditions. But all on sand, as I mentioned before I live near the coast of the Netherlands. The MTB course I ride is in the dunes and riding on these surfaces can be bad for your chain.

The measurements:

Here are the first measurements, nothing shocking on these first kilometres. The Miche chain measured a 132.2mm when I mounted it. After 150km it’s ±132.25mm.


No up to the next kilometres of off-road fun.
