A recent ride saw the demise of our Velocity Dyad 40 hole rear rim. The rim developed circumferential cracks adjacent to the spoke holes.
I ordered another of the same rim, just being lazy. It should arrive soon and will be an easy swap.
When I noticed the cracks, it was after the Saturday ride in Vero with the PANTHERS tandem club. Sunday morning, after lockwiring the spokes to prevent a possible drivetrain lockup, I was talking with Bob Thompson, and he recommended having some taller profile wheels built.
I do have another set of hubs, and am now wondering, without going the cost of specialty wheels, or the price of carbon rims, what is an optimum rim height for the 25mm or 28mm tires. Seems it's a weight vs aero tradeoff.
BTW, my hubs are 40 hole, so whatever I decide will still be 40 spoke wheels.
Veocity offers a few possible choices.
Having discs front and rear, we could run these 43mm tall, 19mm wide / 770 gram
These were popular on some bikes at Vero 30mm tall, 19mm wide / 518 grams
Another possibility and wider 32mm tall, 24mm wide / 650 grams
Our current rims are these. 22mm tall, 24mm wide / 480 grams
This is a balance of cost vs performance for recreation type rides, group events and training rides.
