Internet is often criticized as being too easy accessibile but sometimes it is a cauldron full of useful information and news totally free and usable by all. In this case, a little wandering among the Youtube videos, I have found useful movies that explain how to do proper maintenance of our beloved mountain bikes. Given the already high cost of maintenance at the shops and the economic crisis, it isn't bad to learn a little selfmade maintenance that we could thanks when we ara out in some excursion. In addition, but this is a personal opinion, I find it quite relaxing every now and then to download our tension on bicycle: at the end it does not complain about anything, anything we do!
