• "[The only] hubs which are approved from manufacturer for tandem, load carrying, heavy duty pourpose are the SRAM P5 Cargo, Fichtel & Sachs Torpedo DUOMATIC and the Rohloff Speedhub"
  • Rohloff Speedhub — crazy expensive ($1100), crazy engineering, but you get what you pay for, it's supposed to be pretty bulletproof and maintenance-free
  • SRAM P5 Cargo — very difficult to obtain
  • Fichtel & Sachs Torpedo Duomatic — no longer produced
• OHHH, a few people have the gonads to ask
  • specific hubs that people have used on BMX bikes, and whether or not there were any complaints
    • just get the Rohloff, the rabble yells
    • SRAM Spectro 7 and Rohloff Speedhub are recommended
    • just get the Rohloff!
    • holy crap, the reviews seem to agree... just buy the Rohloff
    • Nexus = no good
  • friction shifter = bad idea, unless it's a 2 or 3 speed
  • yeah, lots of worries about three-speeds being too weak

NOTE: if you do get the Rohloff, BE CAREFUL to not overfill it during the oil change!
