A few of our bars have bent a bit. (We play very wildly and aggressively! =D ) But they can be bent back into shape. (The part can be taken apart relatively easily).
But in fact pretty much every single part can be ordered separately and replaced (and personalised), incl. pucks, players, plexi, sticks, etc. They (STIGA) have done this really well. For example, I ordered a few sticks as replacements (~5€ each). You can also buy lots of different teams (e.g. NHL and International). (I bought Suomi/Finland for 10€). But I ordered them on a foreign website.
