Question about 1x spoke lacing
 

I'm lacing up my new front wheel, Kinlin XR-300 and American Classic Micro 58 24 hole, and am doing a 1x pattern.

I took a look at a set of Xero XR-3 wheels that I had sitting around because I knew the front wheel had a 1x pattern also. I noticed that both the trailing and leading spokes come from the inside of the hub. So all the spoke heads are on the outside.

When laced this way the leading spokes to cross behind the trailing spoke and actually contact it. If the trailing spoke is laced with the head in it won't have contact with the trailing spoke.

Is this how all 1x wheels are laced? Is there any reason why I shouldn't lace my wheel this same way?

Don't copy the xeros. Just lace it the normal way.

Lacing it with all the spokes exiting to the inside of the hub is a slightly more aero approach
than lacing with spokes alternating, Having the spokes in contact with the alternating
approach will put a bit more stress on the spoke. All this is incremental. If you spend a lot
of time above 25mph then the aero version is to be preferred, but you are talking in terms
of less than 100yds difference at 25 miles for the same energy expenditure.

for a 24h, it's better to use radial or 2x.

1x is there for 16h on 700c rims or a combination of very large flange and/or very small ERD rims.

you'll probably notice the shallow angle the spokes exit the hub at and how close the spokes cross from the hub with 1x on 24h.

Hmmm... I think I see where you're going. I have a 24 spoke 1X wheel, but I didn't interlace the spokes because they bent around each other too much. However, that's on a 17" Moulton rim and a high-flange hub: http://home.comcast.net/~jeff_wills/...es/bike042.htm , so I'd tend to agree- 2X on a 700C rim would be better.

Lacing a 24-spoke low-flange hub 1-cross with all the spoke heads "out" would allow the spokes to contact and act like they were interlaced. It avoids a sharp bend in the spoke that would result if the spokes were laced "normally" (head-in, head-out).
