Cleaning your bike

From TrialsWiki

Cleaning your bike is the prime opportunity to check for any problems or notice something that may cause a problem. You may notice a hairline crack or a maybe a bent pin in your chain so clean regulary and you'll find you have less problems in the long run. also make sure to get into the tiny places where the bearings sit to get all the crap out otherwise later on it will get sinside and make the bearings feel like crap this will take a while tho, so give it a GOOD clean.
