I tried once Time MTB copies with Ti axles.
After a few months, the bearings did grind the pedal axle for a mm or so.
It is a question of finding a good Ti alloy provider.
While Walty for instance seem to make frames with high quality Ti alloy, the pedal axles from an unknown seller on Ali is far from certain.
The Ti axles of the original Time pedals I have are bombproof.
I buy the cheap model now, keep the outside, and re-use the Ti axles.
