trike rear wheel

Any recommendations for the best rim on the rear of my tadpole trike. 559
(26") size and using 1.35" to 1.5" tyres.
I assume there are other things to take into consideration because of the
side loading that will be experienced.

On a well-built wheel, most of the strength comes from the tension on
the spokes. A good, hand-built and -tensioned wheel will have far more
tension than a similar wheel built by a machine.

True, a wider rim will be better able to resist the side forces a trike
puts on a wheel, but most modern rims are more than strong enough,
particularly when built properly. I'd recommend a Salsa Semi:

use or a Salsa Gordo if you're really worried about side forces:
http://harriscyclery.net/site/page.c...=49&SKU=RM8619 . Bot are
available in a variety of drillings, up to 48-hole, if you're after the
ultimate wheel. 36 spokes should be adequate- we had no problems with
36-spoke Araya 7X's years ago:

The strength of the flanges on the hub might also be of some concern with a
tightly laced and highly loaded wheel, so don't go cheap and cheesy here.
See what gear the commercial trike builders use on their machines.
