Got a new 17" x 4.5 Harley rim with custom spokes (CognitoMoto)

Trying to relace the stock hub. All inner spokes go through the hub fine.

1/3 of the outer spokes go through fine, 1/3 go through with a little bit more effort, but the last 1/2 I can't seem to get to turn/bend after their inserted. Not sure the terminology but the long stem portion goes through the hub holes fine, but at the 90 degree bend it just doesn't want to go in.

The head (angle) is thicker than the stock ones but not sure why it would just happen to some of the holes and not all. All spokes appear to be the same, I switched out the ones that went in fine for the ones that didn't and they were able to go in.

Any alternatives? Thinking of either sanding/grinding down the spoke heads or drilling the hub? Ideally would prefer to not have to do either, but if it came down to it, assuming the grinding down the spokes would be better?

Not sure if this addresses your problem. When I re-laced my wheels there were 2 sets of spokes for each wheel. An inner set where the head goes on the inside of the hub and an outer set where the head goes on the outside of the hub. The difference is the length of the 90 deg bend. The ones that have the longer length go on the inside of the hub (i.e. fed through the inside of the hub.)

I would not sand down a spoke to make it fit. it will rust pretty quick if it isn't stainless.

Sometimes you have to open holes a bit.. measure diameter. , and compare to stock.
The head should be snug against the hub when finished.

pjlogue - thanks the inners all went in smoothly and are currently laced to the wheel

754 - measure the diameter of the head of the new spoke? if making the hub hole bigger is not frowned upon, can I just file on side, where the elbow / 90' needs to bend just to get it in there? maybe file opposite to the bend so when it does bend the elbow is flush?

Are you sure you didn't get a set of all inside spokes? I know the 16" rims pretty much have to be laced that way.

ChopSticks · « **Reply #5 on:** February 26, 2018, 06:01:06 PM »

jgger - positive their different angles. I ended up drilling the hole a little bit bigger, but for the life of me can't get this to lace right. I can get both insides and one set/side of outsides, but when I try the other outers it doesn't even come no where close to the hole.

Tried probably 2-3 different combos

Now trying to do this time of pattern

but can't get the second inners across the first, almost as if they're half an inch too short

also already tried this method no dice

Even used this as a reference. From the two previous thread above, it looks like the second set of inners is supposed to have 6 (rim) holes across from the corresponding inner spoke that was inserted directly below, but still missing that 1/2" or so even with all the nipples unscrewed almost all the way

Sorry for coming back late , yeah filing will work if done in the right spot.
It's not looking right in the pic.

Uploaded better pic below. Those three sources I linked above all have 6 holes in between the first inner and the one directly on top of it (other side) that crosses over the first

To me it looks like the spoke you are holding should rotate cc and go into the hole marked #3.

The hole numbering of the holes will be different on a 36 hole rim versus a 40 hole rim, I believe.

ChopSticks · « **Reply #11 on:** February 26, 2018, 07:52:32 PM »

jgger - I had originally done that since it fit so perfectly, but the last set of outers wouldn't align with the holes without forcibly bending them and even then it probably wouldn't have been straight

I've attached a mock up of the images in the previous threads linked

2 styles of lacing. Inner cros, infers dont.
Alway take a pic first.
Sometimes you end up with rim or spokes not right.
Did you try changing direction .?
HD has used both ways over the years..

And one more thing compare your old rim and the new one to see if the holes angle the same way.

Chopsticks I don't know. I do know that the 1st time I laced a wheel I had to take it apart a couple of times at the stage you're at right now. If you don't take it all thre way apart you can keep making through same mistake over and over. I pulled mine apart, removed the spokes stacked everything up nice and neat and walked away for an hour or so. Came back with a clear mind then had at it again. I don't even remember what my issue was, but it really helped to take a breather.

I'm sure someone here will be able to walk you through it, hang in there it ain't rocket science.

ChopSticks · « **Reply #14 on:** February 27, 2018, 06:59:33 AM »

754 - do you have an example of the other style of lacing? Just looked at a snapshot from before taking it apart (only have a portion of the whole wheel) but it also appears the be the same 5-6 holes in between the next inner.

jgger - thanks, this will be day 3 and god knows how many hours. I've taken it apart and relaced more times than I'd like to admit. Guess I'll see if there are different examples online. Wish there was a way to lace the first 2 inner and 2 outers to see if the hub aligns correctly in the rim before doing the whole sets first

Are there any downsides to only being able to cross 2 instead of 3? Got the wheel laced with a little bit of elbow grease aka brute force (had to bend the outers) but was still only able to get a 2 cross pattern

754 · « **Reply #16 on:** March 04, 2018, 08:50:28 AM »

Quite often, on kits to mount say a 16 inch rim to a CB 750, they used cross 2 instead of the original 3..
So if that makes it fit, use it.

oh perfect! any idea what the maximum runout tolerances are? Google is returning anywhere from .5mm to 4mm depending on the source. Any way to accurately measure without one of those fancy gauges?

754 · « **Reply #18 on:** March 06, 2018, 03:45:43 PM »

Tryvto get it to .030 inch or better.. that is .75 mm
Alloy rim will be easier if it's well made.
