yep, b r, it looks as if I’m alone on this one. It’s not that it’s so hard to line them up – even I can do it, without recourse to my LBS – more that there might be a better way, even if only marginally so. Progress is full of tiny incremental improvements each of which on their own may make little or no difference to most people, but which collectively lead to significant changes over time; I was vaguely wondering if this might be one of those. The fact that most STW forum dwellers, not necessarily a representative group of the world’s population, find it easy to line up their stems, doesn’t invalidate the proposal. But the balance of cost, complexity, strength, and so on, relative to the size of the problem (tiny) that has been pointed out by some on here probably does.
But really, it was just a flippant suggestion. For my next thread I think I will suggest alignment notches on rims, with corresponding nubs on tyres, so we can get logos lined up with valves….
