It's now already the second time that the rear wheel has issues with side to side wobble and I would like to understand why this is happening.
The first time I had a bike mechanic to tune the true the wheel spokes but then it happened again.
I am not 100% sure but I have the feeling that both times it happened on occasions where I was carrying around 10-12 kilos in a single pannier (on the left side).
Mine is a mountain bike with a rear fitted pannier rack which can support up to 25 Kg of weight.
I know that carrying over 10 kilos on just one side is not ideal, but when I do so is only for a very short distance.
Anyway, I was wondering if that could in any way cause problems to the wheel spokes?
