Hi. I am a novice. Have a new Jamis Coda Sport hybrid and am already fumbling around w/ it .....Had trouble centering front wheel with brakes after removing it and putting it back on. I am not mechanically inclined but I think basic things can be taught and learned hopefully. So REI is offering a free 90 minute class on basic bike mechanics. Description below. Has anyone taken it and found it helpful, or just a waste of time. Not sure if this question shuld be in the general forum....maybe more newbies would see it then. Thanks.

REI Class Description: If you ride a bicycle, then you need this class! In this informative session you will learn how to lube a chain, fix a flat tire in record time, and make other minor adjustments to your bicycle that will keep you riding smoothly and prolong your bike's life. No experience necessary! Note that this is a demonstration class; please do not bring your bike.
