Here is my 1992 Diamondback Sorrento, before and after a few mods (handle bar, stem, seatpost and rack). The previously installed bar ends were not that comfortable and too far from the brakes, although they did provide a more upright riding position. New bars and stem do the same thing but a lot safer!! Old seat post had the 2 bolt clamp mechanism and slipped even when tight, new post has one bolt adjustment; for and aft and tilt. Rack is just a good thing to have as I like to carry tube, pump, CO2, patches, tools, first aid kit, phone and energy bars when I ride....just in case!
