Radial spoked 20" wheel?

M. Chandler said:

I'm building up a new front wheel for my LWB recumbent, and have been
toying with the idea of lacing it with a radial spoke pattern. The rim
is a Velocity Aeroheat (ISO 406) and the hub is a Shimano LX unit. Even
with such a small, lightly loaded wheel, would the radial pattern be a
really bad idea?

I have seen several cases of people having problems with radially built
wheels on the front of Easy Racers, which is a similar loading condition
to your bike (estimated 35%/65% front/rear weight distribution).

Sounds like insufficient tension to me. My wife's Tour Easy has a
28-spoke front wheel laced radially, and it hasn't had to be trued or
tensioned since I built it 4 years ago- it used to be on the front of
my Lightning. The front wheel of my Tour Easy was laced radially until
a truck ran over it- I relaced it with an Alex rim, which required
1-cross lacing in order to reuse the same spokes.

(I know Jobst will probably slap me upside the head for switching
lacing patterns and head in/head out spokes, but so far, no problems.)

I don't think that can be decided without knowing more about the nature of
the problems. For example, what if they were hub flange failures?

I have generally used radially laced wheels on the front of LWB bikes
with _NO_ problems.

The wheels I used were mainly ones that I built myself and most of the
miles were using Airfree Tires.

It was a matter of the spokes coming loose, so it may just have been a
build problem. The wheels were re-laced on the same hubs two-cross and
have not had problems since (as far as I know).

Lewis,

How high was the tension on the spokes on your wheels?

Well, what will be better about it? Stronger? no. Lighter?
Sure, by the weight of a few mm of spoke length.

There are known flange failures from radial spoking but it's
not all that common, either ( manufacturer's warnings
notwithstanding).

There's probbaly no harm on a small wheel, they being
generally less trouble radial than bigger ones, but it won't
make anything better, either. If you think it's pretty, go
for it.

Ah. I believe Sheldon Brown has mentioned that this can be a problem with
radially laced wheels, because the spokes are more in line with the holes
in the rim, and this creates less friction between the nipples and the rim,
which are thus more apt to turn.

I have not measured it but, as with all wheels using Airfree Tires, the
spokes need to be _really_ tight.

I have a arrowhead laced such 36 spoke I think on my road bike it has held up
very well under my weight and abuse.
