Introduction: Lacing Bike Wheel : 36 Holes Hub to 32 Holes Rim

About: Just an ordinary person who loves #thinking and #tinkering

Do you buy a mismatch hub and rim of a bike wheel? I just did. I never noticed that the new Shimano hub I ordered has 36 holes. If only that store had a pair of rims available, it would have been easier to lace the wheels. Then I ordered a new pair of rims from separate store. I am new to bike's parts and technology. I do carefully count the spokes on my old wheel and yes I ordered 32 holes 26" rims. When both parts arrived, it felt like doomed.

Searching around the web gave me no workaround. I read that there are many out there, and the senior/pro keep telling us to get a new pair of rims. This is not working for us who live in a small town where local bike stores do not sell fancy rims.

Then I give it a try by myself, building my first pair of wheel. Not bad. For those who have the same problem you can give this a try.Some said we need some spokes with different length, but I would say that you need not if you have a double wall rims. Some spokes do pop out about few millimeters from the nipples but I would say no worry for they are still under the second wall of the rim.

I adopted a new method, similar to "three cross pattern" but differ from the conventional wheel building method found on the web. You need "the working sheet" above to follow this instructable easier and clearly, print it out if possible. It will help you lacing the wheel easier.

Step 1: Preparation

  • Rim (32 holes).
  • Hub (36 holes, 18 holes at each flange).
  • 32 pieces of spokes.
  • 32 pieces of nipples.
  • Few foam boards from refrigerator or tv set will help reducing scratches on the floor and rim.
  • A flat head screwdriver.

Place the hub in the middle and the rim around it. I start with the non-driving side up (the left side of wheel). I will use the terms Inside-out spoke that is coming from the inside of the hub flange and the vice versa Outside-in spoke where you can differ them from the picture above.

Step 2: Initial Spoke and the Red Spokes

I use the color code "red spokes" regarding to my working sheet. Find the valve hole for it is our guide for the initial spoke. The holes on the rim are slightly offset, if you look at them carefully. You can see that they are slightly up or down alternately.

First we are working with all the outside-in spokes. Put your first spoke in one hole of the hub then go through the hole on the rim that is slightly up (either on the left or right of valve hole, it is on the left in my case). Then put the nipple on the spoke to lock it on the rim. Five or six turns on the nipple is good.

Then go on with all the red spokes namely on hole 4, 6, 8, 10, 13, 15, 17 on the hub counting clockwise. On the hub flange we leave 2 holes between 1-4 and 10-13. On the rim, we leave 3 holes in between two spokes.

For easier to read on my working sheet, I mark the number on flange with colors. If a number has two colors it means one color is put on top flange and the other is put on the lower flange.

Step 3: The Blue Spokes

Flip the wheel over so that the driving side facing up. Locate your hole #1 and counting clockwise we get the hole #2 on the left. We are building based on our working sheet, the colors, the numbers on hub. We are still working with the outside-in-spokes.

The first blue spoke goes to the right side of the initial red spoke on the rim. In my working sheet, the blues are on the left of the reds because it is viewed from non-driving side, we have flipped the rim remember? It is good if you can imagine that your spokes have colors, otherwise.. you can mark it with color sticky notes. Now put all the other blue spokes on the hub namely hole number 3, 6, 8, 10, 12, 15, 17. All blue spokes goes to the next right holes of reds on the rims.

Step 4: The Orange Spokes

Flip your wheel over so that the non-driving side is facing up. Turn the hub counter clockwise. For orange spokes we are now working on inside-out spokes. These orange spokes are red spokes partners on one flange.

Start from the hole #3 on the hub (from the inside out), the orange spoke goes clockwise and make three cross to three red spokes. The first cross is from the above (up), the second cross is from above (up) and the third cross is from the below (down) the red spoke it passes. You might need to bend the spoke a little to bring it down the other spoke. Do not bend too much. Then it goes to the left of the blue spoke on the rim . So it is between a blue spoke and a blank hole on the rim after crossing three red spokes.

Put all the orange spokes on namely on hole 5, 7, 9, 12, 14, 16, 18 on the hub. They are all goes to the left of the blue spokes on the rim. There you can see we leave two holes blank on the flange without spoke.

Step 5: The Green Spokes

Flip the wheel again so that the driving side is on top. We are working with the inside-out spokes. Note that these green spokes are partners to blue spokes on the other flange.

Start from the hole #2 on the hub (from the inside out), the green spoke goes counter clockwise and make three cross to three blue spokes. The first cross is from the above (up), the second cross is from above (up) and the third cross is from the below (down) the blue spoke it passes. As on orange spokes you might need to bend the spoke more to bring it down the other spoke as our wheel is now getting tighter with more spokes. Try not bend too much or straighten it back after reaching the hole on the rim. It goes to the empty hole on the rim after making three crosses to the blue spokes.


Put all the green spokes on namely on hole 5, 7, 9, 11, 14, 16, 18 on the hub. They are all go to empty holes on the rim. Here we leave another two holes blank on the flange without spoke.

We are done. We are heading to the next level that is truing the wheel. Hope I can serve you another instructable on that one later ;)

Depend on the size of your rims. There are many "Spoke Calculator" on the net, or simply ask the local sellers and they will give you the correct size.

Anyway to lace a 36h hub to a 28h rim?

Answer 1 year ago

Technically yes. Then you will have 8 unlaced holes -- 4 holes at each side.
Your wheels will not fail you on daily riding, just don't use them on extreme riding or bmx jumpy ride.

Thanks for the help, how can I make your lacing pattern to work with this.

Draw a circle on a piece of paper and write down hole number 1 to 18 (this is one side of the hub).
While lacing you can skip hole number 4-9-13-18.
At the other side you can skip hole number 2-7-11-16.
Then you will get balanced-strength of spokes on your wheel for daily riding ^_^

Question 1 year ago on Step 5

Hello.
I would like to settle a 18 inch shell with 20 holes on a Nexus 8 hub (with 36 holes).
I plan to use the 1, 4, 8, 11, 15th holes for the red spokes ... I plan to use the 18th, 4th, 7, 11 and 14th holes for the blue ones...the 3, 7, 10, 14, 17 for the orange ones and the 2, 6, 9, 13, 16th for the green ones...
I notice that there is no spoke on the 5th and 12th holes of the hub...
Do you have you any idea ?
Perhaps I also may tell you I would like to settle the spokes on the non driving side in the vertical plan and those of the other sides more inclined.

Thank you for your advices.

PS : It is for a street performance with a barrel organ I need a 18 inch wheels on a nexus 8 hub to make the barrel organ work with a belt...

In my opinion, as long as you do not use it for extreme sports and the tracks you are running daily is not that kind of off-road tracks, that will be okay with 20 spokes.
36 - 20 = 16 holes to be left-out. Just distribute them evenly and do at least 2 crosses on each spokes I think that would be okay.

Question 1 year ago on Step 4

Hello,
Step 4, on your picture there are three crosses while on your schema there are more crosses (4 or 5). Is your schema right ? Thank you

Going few years back I need to refresh my mind for a while :D
When you see 4 or 5 crosses, you are counting with the blue spokes which are on the other side of the working-face. The same side is the red spokes. So 3 crosses is supposed to be with the red spokes, that's why on the next photo I use my palm to better viewing the crosses and blocking the other-side spokes.

Yes, I should had drawn the diagram with grey-out style or dash line :D

Hey Chienline,

thanks for saving me the headache of buying new hubs. Tried it the other day on both my rims and worked really well.

For those interested, I swapped my hub from 36 hole rim to a 32 hole rim and I managed to make it work with spokes of one size. The spokes for the 32 hole rim were 4mm longer than the original ones, and some where sticking out a bit. If I were to do it again, I would lace red and blue with standard length, and orange and green with extra length spokes.

You are welcome, Chris.
Yes you are right about "we need 4 shorter spokes" but I just couldn't get them here in my home town. Thankfully I have double wall rims, so the excessive spokes inside the rim do no harm to the tube ^_^

Thank you a lot !
I just put my nexus 8 hub on a nice green hoop thanks to you =)
I was just wondering... I had to use 4 different spikes sizes, but still some spokes are really more tightened than other ones.
Can you tell me if your wheel did stay true a long time ? Or did you have to true it more often than "normally spoked" ones ?

Normal riding, no issue so far ^_^
I think only 4 spokes out of 36 will bring little to no effect on normal riding. If you go extreme sport, well, better pick appropriate gears for that purpose :D

Question 3 years ago on Introduction

Hej chienline,

how did you calculate the spoke lengths? Used any spoke-calculator on the internet?
