Despite my initial reservations, the Ltwoo works really well (easily Tiagra, 105 level, but so does most shifting systems when they are well cabled and tuned... )
No point hanging onto the Neos, imho, its just trying to extend the life of a dead horse and then you when you get further issues on the neos, you might
1. No longer be able to find the RD hanger (due to lack of demand )
2. Think that you spent time/effort making the Tourney+Neos work, so you want to find another Neos (dead horse) replacement..
Agree, with a couple qualifiers.
- If the (separate, replaceable) RD hanger is recessed into the right dropout, yes, it must be the exact correct hanger, and there are far too many different ones (was recently a whole thread about that). My guess is it will still be available, but I could be wrong.
- If the RD hanger is not recessed into the right dropout, then it would probably require a claw-mount hanger under the right axle nut or quick-release, and that is pretty standard, easily available. If the bike is 7-speed rear, you can get a whole derailleur with integral claw mount for less than the cost of a claw mount hanger. $13 bought me a new Shimano Tourney TX RD, GS (mid) length cage, designed for 6/7 speed, works amazingly well for standard folder 1X (11-30, but should work up to 34) or 2X system, it has enough capacity for that. Vastly better shifting than the stock Neos RD.
