Now that I think of it, I haven’t touched either of my AXS derailer systems. On the fuel EXE T-Type derailer, the LBS set it up in January …haven’t touched it since.The benefit of either system is that once adjusted there is no reason to have to do any further adjustments. I have not touched my AXS for 2.5 years! Possibly ( not yet had time to prove this) but T Type AXS should require even less given there is no high/low or B tension adjustment.
As far as the cost of those systems …I could have a really good time in Vegas for about a week or more for the same price. (including flight, hotel, meals, taxes and taxi ). Or I could have a clean cockpit, avoid getting tangled in cables when I go OTB’s, enjoy smooth shifting etc…
