Not yet. I live in the snow belt and do not ride when it is cold. But in Feb I completely go thru my two wheel recumbent and my trike. The whole drive chain is cleaned and relubed. The chain gets a complete cleaning and check for wear with both my Park tool and a steel rule. They will be replaced is wear is indicated. All nut bolts and screws are checked. Doing this, I seldom have any problems while riding in the summer except for an occasional flat.
