Following the mishap I described a couple of post back in which my Planet X’s hanger got bent, I’ve bought a hanger alignment tool. I just went for the cheapest one I could find (on eBay) but it seems nicely manufactured. I may only ever use it once.
It turns out that the Planet X’s saddle got chewed up in the same mishap. I bought a new one off Amazon. It was only £10, about 1/5 of the cost of the Prologo saddle it’s replacing. But again it seems well-made and comfy, and it even has green trim to go with the frame. And a gap down the middle, which the old saddle didn’t have. Which if nothing else will make it easier to get at the forward allen bolt that secures it to the seat post.
