I'd never heard of mechanics' stethoscopes; thanks for bringing them up. But question: most creaks and clicks on bikes occur only when riding. How do you use one of these while on the bike? I think in particular of bottom bracket and seatpost noises. (And I can imagine the looks you'd get riding along earnestly listening to your headset with a stethoscope. You'd have to wear a white lab coat.)
And +1 for threadless stems with multi-bolt bar clamps for very wide or high or swept-back bars; I much prefer how quill stems look (well, unless they're raised very high) but sometimes they're not up to the job.
