With November's arrival, I pondered the thought of laying around for yet
another winter, watching my legs atrophy and my gut expand, and decided
that a wind trainer might be a reasonable alternative.

I chose the Racer-Mate "Piggyback" model.  I believe it has a number of
design features that make it superior to conventional wind trainers.
Frame support is entirely on the dropouts, rather than on the bottom
bracket shell.  You don't have to remove the front wheel, and since the
front forks don't get clamped into a mousetrap arrangement, there is
no risk of fork damage due to torsional stress.  It attaches quickly to the
bike with two thumbwheels and takes up little storage space when not in
use.

Wind load is somewhat less than what I'd experience under actual conditions,
but there's only about one gear's difference, with a 24-13T 6-speed freewheel
and a 52-42T crankset.  The experience is a lot more like actual riding than
what I've gotten from conventional exercise bikes.  After 20 minutes of
spinning at about 95 rpm, I was drenched -- a good workout.

The only disadvantages to this trainer are the unshrouded fans, which could
be a safety hazard; they're within easy reach.  Also, you have to
replace your quick-release skewer with the one they provide, so as to fit
correctly into the clamps.  Aside from these drawbacks, I highly recommend
this trainer.
