The Complete Guide to Building a Bicycle Wheel

How a wheel is built by hand, the way it is done in a professional workshop — from choosing parts to the final truing.

Building a bicycle wheel by hand is one of the most rewarding skills a cyclist can learn. A hand-built wheel is stronger, lasts longer, and can be repaired indefinitely — unlike a factory wheel that often gets discarded when a single spoke breaks. It is also the heart of what a wheel-focused workshop does every day. This guide walks through the whole process so you understand not just how, but why each step matters.

1. The Tools You Need

You can build a wheel with surprisingly few tools, but a handful of them make the difference between a wheel that merely holds together and one that stays true for years:

• A truing stand — holds the wheel and shows lateral and radial deviation as you work.
• A spoke tension meter — the single most underrated tool. Even tension is what makes a wheel durable.
• A spoke wrench sized to your nipples, and ideally a nipple driver to speed up the initial threading.
• A dishing tool — to check that the rim is centred over the hub.

Tip: if you buy only one "extra" tool, make it the tension meter. Most wheel failures come from uneven or insufficient tension, not from the lacing pattern.

2. Choosing Your Components

Hub

The hub determines the spoke count (commonly 24, 28, or 32), the flange diameter, and the spacing between the flanges. All three feed directly into spoke length and into how stiff the finished wheel will be. For choosing a rear hub specifically — and decoding what the spec sheet hides — see the rear hub guide.

Rim

Pick the rim first if you can, because its ERD (Effective Rim Diameter) is the most important number in the whole calculation. Note also whether it is drilled for a specific lacing offset.

Spokes

Double-butted stainless spokes (such as DT Swiss Competition or Sapim Race) are the sensible default: lighter and more fatigue-resistant than plain-gauge, while keeping strong full-diameter ends. For the full picture — plain vs butted vs bladed and how to rank them — see the choosing spokes guide.

On a rear wheel you can also run different spokes left vs right — and even different spoke counts — to fight the slack non-drive side. See the asymmetric rear wheel guide for the recipes and the trade-offs.

Nipples

Brass nipples are the durable choice and rarely seize; aluminium nipples save a few grams but are far less forgiving. For a first build, use brass. There's more to nipples than material — length interacts with spoke length in ways that catch people out; see the spoke nipple guide.

3. Calculating Spoke Length

Spoke length is derived from five numbers: the rim's ERD, the hub's flange diameter, the centre-to-flange distance on each side, the spoke count, and the lacing cross. Because a rear wheel's two sides differ, the left and right spokes are usually different lengths.

You don't have to do the trigonometry by hand — any reputable spoke-length calculator will do it once you have measured accurately. The key is accuracy: an error of even 1–2 mm can leave nipples under-threaded (weak) or bottomed out (impossible to tension).

Tip: measure your own ERD rather than trusting the spec sheet. Rims vary, and this single measurement has the biggest effect on the result.

4. Lacing Patterns: Radial vs Cross

In a radial (0-cross) pattern the spokes run straight from hub to rim. It is light and laterally stiff, but transmits no torque, so it is only used on non-driven, rim-brake front wheels. A crossed pattern — most commonly 3-cross — lets each spoke cross three others, transferring braking and drive torque smoothly. It is the durable default for almost every rear wheel and most disc-brake fronts.

There is also the question of spoke direction through the flange. In this workshop's vocabulary, a spoke laced from the inside of the flange outward is called an inpoke, and from outside inward an outpoke — the choice affects how the spoke head seats, which matters most on radial and low-flange builds.

On crossed wheels you can also bind and solder the crossings — spoke tying and soldering. It does something more specific than "add stiffness"; see the deep dive for what it actually does and when it's worth doing.

One thing that catches builders out on crossed wheels is the rim's hole offset — get it wrong and the spokes straddle the valve. See rim spoke-hole offset for normal vs reverse rims and the left-drop / right-drop rule.

5. Building the Wheel, Step by Step

1. Lace the first group of spokes (the "trailing" spokes of one side) and thread the nipples a few turns each.
2. Add the leading spokes of the same side, then repeat for the second side, weaving the crosses as you go.
3. Bring every nipple to the same shallow starting tension so the wheel is roughly round and centred before any real load goes in.
4. Increase tension gradually, a half-turn per nipple at a time, working around the wheel rather than tightening one area fully.

6. Tensioning and Truing

This is where a wheel is made or ruined. Using a tension meter, bring the spokes up to the rim's recommended tension while keeping the two sides balanced. Then, on the truing stand, correct the wheel in this order: lateral (side-to-side), radial (up-and-down), and dish (centring). Each adjustment affects the others, so work in small increments and recheck.

Finally, stress-relieve the wheel by firmly squeezing pairs of spokes around it. This settles the spokes into the flanges and reveals any that will detension later, so you can correct them now rather than on the road.
