Wheel lacing: angle flange hub
Notes:
- See Figure 2-26. The following procedure is valid for wheels that use an angle flange hub regardless of rim style or diameter.
- The primary brake side of the hub has one or two grooves cut into the disc mounting surface.
Figure 2-26. Angle flange hub: 1. Outer spoke hole; 2. Inner spoke hole
1. Place hub on workbench:
- a. Front: primary brake side up.
- b. Rear: brake side down.
2. Install all spokes in the lower flange.
3. See Figure 2-27. Flip hub over. Gather all outer spokes and hold upright with a rubber band. Repeat with the inner spokes using a second rubber band.
Figure 2-27. Spokes gathered: 1. Outer spoke; 2. Inner spoke
4. Install spokes in remaining flange.
5. Rotate the lower flange spokes as far as they will go:
- a. Outer spokes clockwise.
- b. Inner spokes counterclockwise.
6. Center the rim over the hub and spokes assembly and support on wooden blocks approximately 1.5 in (38.1 mm) thick.
- a. If valve is not located in the center of the rim, place valve hole facing up.
- b. If the valve located in the center of the rim can be placed either side up.
Note. Install nipples until approximately 1/8 in (3.2 mm) of spoke thread shows.
7. Install lower flange outer spokes and loosely install spoke nipples:
- a. Rim with side valve hole: See Figure 2-28. Start at the valve stem hole (1).
- b. Rim with center valve hole: See Figure 2-29. Start at the first hole counterclockwise (1) from valve stem hole.

8. Install remaining outer spokes in every 4th hole.
9. Install lower flange inner spokes and loosely install spoke nipples:
- a. Starting at the 2nd hole counterclockwise (2) from first spoke installed, install inner spoke.
- b. Install remaining inner spokes in every 4th hole.
10. Carefully release upper flange inner spokes and fan out around rim, rotating them clockwise.
11. Starting at the first hole counterclockwise (3) from first spoke installed, install inner spoke. Install all remaining inner spokes in every 4th hole.
12. Carefully release upper flange outer spokes and fan out around rim, rotating them counterclockwise.
13. Install outer spokes in remaining holes (4).
14. Verify spoke heads are seated. See 2.7 CHECKING AND TRUING WHEELS.
- a. Evenly hand-tighten spoke nipples until snug.
- b. Only tighten until slack is removed.
- c. Proper torque will be applied when the wheel is trued.
- d. Adjust offset and true the wheel.
Wheel lacing: straight flange hub, single hole circle
Notes:
- See Figure 2-31. The following procedure is valid for laced wheels that use a straight flange, single spoke hole circle hub regardless of rim style or diameter.
- The primary brake side of the hub has one or two grooves cut into the disc mounting surface.
1. See Figure 2-30. Divide spokes into inner and outer groups.
Figure 2-30. Spoke heads: 1. Short head (outer spoke); 2. Long head (inner spoke)
- a. Inner spokes (2) have long heads.
- b. Outer spokes (1) have short heads.
2. Lubricate all spoke threads and nipple shoulders with tire mounting lubricant.
3. Place hub on bench with the primary brake disc side up.
4. Fit the first two spokes.
- a. See Figure 2-31. Insert one outer spoke (1) (short head) into any bottom flange hole and swing it clockwise.
- b. Insert an inner spoke (2) (long head) in the next hole counterclockwise from the outer spoke.
- c. Swing the inner spoke counterclockwise over the outer spoke.
Figure 2-31. Lacing single row wheel hub: 1. Outer spoke (short head); 2. Inner spoke (long head); 3. Hole directly above two spokes
5. Find the hole (3) in the upper flange directly above the first two spokes. Insert a long head inner spoke.
6. Insert all remaining spokes in the upper flange, alternating the inner and outer spokes.
7. Flip the hub (primary brake side down). Install remaining spokes alternating inner and outer spokes.
8. See Figure 2-32. Group all spokes on the upper flange into two bundles of equal numbers. Secure each group with throttle grips.
Figure 2-32. Bundling top spokes
Note. Outer spokes must not cross an outer spoke. Inner spokes must not cross an inner spoke.
9. Angle all lower flange spokes as far as they will go without overlapping a LIKE spoke:
- a. Outer spokes (short head) clockwise.
- b. Inner spokes (long head) counterclockwise.
10. Support the rim on wooden blocks approximately 0.75 in (19 mm) thick.
11. Place the hub and spoke assembly into the rim and centered in the rim.
Note. Install nipples until approximately 1/8 in (3.2 mm) of spoke thread shows.
12. See Figure 2-33. Beginning with the 2nd hole counterclockwise (1) from valve stem hole, install lower flange outer spokes (short head) in every 4th hole. Loosely install spoke nipples.
Figure 2-33. 40 Spoke single row straight flange hub
13. Beginning with 4th hole counterclockwise (2) from valve stem hole, install lower flange inner spokes (long head) in every 4th hole. Loosely install spoke nipples. Each inner spoke will cross four outer spokes.
Figure 2-34. 32-Spoke single row straight flange hub
14. See Figure 2-35. Carefully release each top bundle and fan the spokes around the rim edge.
Figure 2-35. Fanning top flange spokes
15. Rotate all the upper flange inner spokes (long head) clockwise, one at a time, leaving the outer spokes (short head) resting on the rim.
Note. Be sure outer spokes do not fall under the inner spoke and become trapped.
16. See Figure 2-33. Beginning with the first hole counterclockwise (3) from valve stem hole, install upper flange inner spokes (long head) in every 4th hole.
17. Rotate outer spokes (short head) counterclockwise and install in the remaining holes (4) in the rim.
18. Verify spoke heads are seated. Evenly hand-tighten spoke nipples until snug. Only tighten until slack is removed.
19. Adjust rim offset and true the wheel. Tighten the nipples to specification. See 2.7 CHECKING AND TRUING WHEELS.

9. Support the rim on wooden blocks approximately 0.75 in (19 mm) thick.
