No problem. If you just give it a very detail cleaning you can spot what may be going bad.. A little bit of old time 3 in one oil goes a long way to lube brake pivot points, derailer Etc. Wal Mark has some cain lube in the auto section I use it . dont know if it for bicycles but it seems to beok. Do check your chain because it will wear out you sprockets when it gets stretched. A good chain breaker and New master link is a great thing to have, Buy a good one. the ones in Wal Mark will break in a heart beat. Parks or some other major brand. I use a master link called "Magic Link" Easy to put on and works well. Good Luck and happy cycling
