What is the superior way to keep the chain
straight on tandem bikes?
I once saw a small chainwheel, slightly bigger
than an RD pulley wheel, in a vertical track,
so it could be adjusted up/down to interfere
with the chain.
This made sense to me, maybe because
I understood it, but I have since then seen
modern tandems and they don't have it.
Sure, many drive formats.
What I meant is that bolts should be in shear to the extent
possible. A stack of spacers under a bolt leads to bent bolts.
