Mountain biking can be tricky for insanely long trips it probably is a good idea to bring a lot more than I usually do which isn't a whole lot. A pump, some tools, a helmet and gloves. What I probably should be carrying is some fix a flat. Oh and yeah of course I have a pump with an adapter.
My first real MTB is a Diamondback Line. However I played around with some Trek ones too and really liked them. I only recently got back into it so I don't really call myself an expert what I do know is I had a checklist of sorts:
I will testify that the diamondback, if it is done through them, is insanely easy to assemble. I actually followed the online video and was done in five minutes. So why didn't I go local for the first one? I didn't want to get upsold. Next time, I definitely will go to a shop and custom order online through them so they can tune it proper. As it is I'll need to take in soon to get it tuned. So there is a con to ordering a MTB online.
