I’ve got to think it’s very individualized. I suspect there’s quite a few here that will still be riding drop bars until they’re no longer riding. For me at 69, I’m not seeing a reason why I wouldn’t continue to use drop bars indefinitely. They come in handy riding in the wind and also pulling friendly pacelines. I’m fortunate to continue to have excellent flexibility so maybe that helps. My biggest question is when might I just lose interest. I know I’m not as “excited” about riding as I once was but I still enjoy it. For me it’s all about finding and planning new adventures or doing something different.
My brother continues to ride drop bars but raised his bars to where his drops are now not much lower than what the hoods once were. He likes the various positions it offers and now is more upright.
