Friday my Karuykan throttleboss pair and knurled rings arrived at the bike shop. The extended screws, which I ordered, were not long enough to go through the stilletto bar ends, throttleboss, and into the hand grip. After looking around all day Saturday for longer screws my wife suggested that we go to Lowe's. She made the suggestion earlier, but I was reluctant to go because I had already tried Home Depot. Sunday afternoon we found the screws I had spent most of the weekend looking for (size 4-40 1.5 inches long). Once again my wife saved the day.
