Looking to replace a 50mm axle.
I can go with OEM which is ~$300 (Top Kart) or any number of aftermarket such as PKT, Righetti, Swift. PKT seems to come up often as well respected, so I looked into that. They sell “D” variants, which are apparently “mild steel” tubing as well as a “chromoly” variant. Is one better than the other? I’m guessing I should be buying the -19 non-D variant for a medium stiffness axle?
Finally, I was thinking to go with PKT, but are Swift and/or Righetti just as good options? i.e. as long as I avoid garbage brands, are all of these OK and I should just buy the cheapest one?
