Nextie Premium NGX 50 700c spoke length

ERD 540 mm, made in 16, 18, 20, 24, 28, 32, 36 hole. Pick your hub in the calculator for your exact spoke lengths.

Rim

Choose the rim

ERD 540 mm, made in 16, 18, 20, 24, 28, 32, 36 hole.

Washers under the nipples (optional), mm thick

Some alloy rims use them. Leave empty if you don't.

How to measure ERD yourself

Take two spokes of a known length and screw a nipple onto each until the thread end is flush with the top of the nipple. Drop them through opposite spoke holes so the nipples sit in the rim as they would in a built wheel. Pull them tight towards each other and measure the gap between the bent ends. ERD is the gap plus both spoke lengths.

Hub

Search hubs (optional)

Choose the hub (50 fit this rim)

J-bend. Flange diameter 57 / 59 mm, centre to flange 32 / 19.6 mm (left / right).

Lacing

Spoke holes

Crosses, left (disc side)

Crosses, right (drive side)

I've started you on 3-cross for 28 hole, which suits most wheels. Radial is only for a side that doesn't brake or drive: a rim-brake front, or the non-drive side of a rim-brake rear.

SpokesSpoke type

Used for the stretch, the weight and the ping note.

Tension, tighter side, kgf

Most wheels 100 to 130. Check your rim's limit.

Spokes come in

Allow for spoke stretch (spokes stretch a little once they're tight, thin ones most)

Spoke lengths

Check your rim and hub against the maker's sizes before you order spokes.

Rear wheel, 28 hole, J-bend spokes, 540 mm ERD.

Side	Spokes	Length
Left (disc side)3-cross	14	266 mm265.7 worked out
Right (drive side)3-cross	14	264 mm264.4 worked out

Rounded to the nearest mm. Between two sizes, go for the shorter one.

Tension: the left spokes run at 62% of the right side's tension. Bracing angles 6.9° left, 4.3° right.

Weight: these spokes and alloy nipples come to about 168 g (about 186 g with brass nipples).

Nipple length

Ping tuner: what each side should sound like

B4, about 488 Hz at 68 kgf

D#5, about 632 Hz at 110 kgf

Pluck each spoke between the rim and where it last crosses another, and match the note. Every spoke on one side should sound the same. It's a guide to even tension by ear, not a tension meter.

Often needed with this wheel

A Garbaruk cassette
Gravel and road cassettes for XDR, XD and HG freehubs.
Nextie tubeless tape and valves
Ready for the tyre when the wheel is built.

These lengths come from the makers' published sizes and a standard sum. Rims and hubs vary from batch to batch, and sizes you put in yourself are only as good as your measuring. Travers Bikes takes no responsibility for spoke lengths worked out with this calculator, or for spokes, wheels or parts bought or built using them.

Want me to build it?

I hand-build wheels in Rochford with Nextie carbon rims and Hope, DT Swiss, Chris King, Shimano, Nextie and SON hubs. I work out the spokes and order them, so getting the length right is my job, not yours.
