I recently purchased a Raleigh Technium Tri-Lite pro (this one: http://backroom.hardsdisk.net/images/raltecbefore.jpg). I was wondering what kinds of maintenance I should perform on it prior to using it as a daily commuter. Would it be smart to do some of the deeper maintenance like greasing bearings in the bottom bracket and wheels? Otherwise I was just going to take it to a shop that has a $30 special for a tune up including truing which I don't think I could do well. Also, does anyone know what size bearings would be inside of the hubs/crank/headset so I can order the proper parts if need be?
