I’m pretty comfortable washing my bike and cleaning/lubing the chain, but that’s all I’m doing for bike maintenance so far. I’ve had my bike for almost 2 years (first bike; ‘15 Niner Rip 9 RDO), ride about twice per week (more when the days are longer), and put in new brake rotors and pads (with help) in April ‘17. I had my bottom bracket serviced in August ‘17 at a local bike shop. Is there some sort or maintenance schedule I should follow? I realize there are a lot of variables here, and I’m both willing to learn basic maintenance myself and willing to pay LBS to handle more complex maintenance.
