My Sturmey Archer XL-FDD has 22,000+ miles, 4,200 on tour, with only a sealed bearing change at 17,000. Been set and forget the whole time for both the power and drum brake, zero busted spokes too. It has near zero effect on speed. Vietnam in winter needs lights every day, they are on 100% of the time now anyway. My hub cost about $130 for 100% reliability. Only SA hubs are easily serviceable. Those other brands with loose bearings are goofy IMO. Using battery lights is a laughable concept. Rim rub gizmos are 100% STUPID.
