>>1618554some of the cheaper V brakes are a little thin/flexy and the spring holders and adjusters do not hold up so well
the brake bosses can wear out and on some frames they are threaded in so can be replaced
only other thing is to keep an eye on the front derailleur cable, top swing front derailleur tend to strain and fray the cable more
its a meh but trusty sort of bike, should last a while and is worth throwing a few parts at as the old ones wear out
