Sorry for writing this in english, but my german is not very good. I started mountain biking last summer during lockdown and have enjoyed it a lot. My first bike was the Trek Marlin 7, and although it has been a good bike for climbing, the downhill is not what I want it to be. I want to buy a full suspension bike but I can't afford anything more than 1800, and I don't know if I should pay to have my Trek Marlin services/fixed to then sell for more money for a full suspension. Does anyone have any tips?
