The S-A "K" family of hubs was ~advertised~ as tandem suitable
and they come up on ebay-uk with regularity, but I'm skeptical that they'd really give better service than a new SRF3.
And, well, 74 years ago S-A didn't flinch when recommending the AW for tandems.
Folks swore these hubs gave good service on tandems, too:
Anyway, my notes say Christine @ www.take2move.de in Germany was able to source a SRAM S5 Cargo.
Me, on a budget? I'd probably go out-of-phase and spread the frame to 129mm, then fit a S-A RSRF3. Not expensive, and has a solid axle.
The S-A XRF8(W) can get down to 116mm OLD (close enough) and has a beefy, solid axle, but you'd get into issues (mostly more expense) of regearing the drive crank.
- Sturmey Archer made both KT and AT hubs for tandem use. Both had larger drum brakes than the KB or AB. I do not know if the internal gears were stronger.
