e*thirteen Sidekick Pro SP rear 148mm (straight pull) spoke length

Straight pull, 28, 32 hole. Flange diameter 38.5 mm left and 54 mm right, centre to flange 37.5 mm left and 20 mm right. Spoke offset 1 mm left, 1 mm right. e*thirteen set the lacing on this hub, and the calculator follows it. Pick your rim in the calculator for your exact spoke lengths.

Rim

Choose the rim

ERD 591 mm, made in 24, 28 hole. Asymmetric: the spoke holes sit 3 mm off centre, allowed for in the lengths.

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 (39 fit this rim)

Straight pull. Flange diameter 38.5 / 54 mm, centre to flange 37.5 / 20 mm, spoke offset 1 / 1 mm (left / right).

Lacing

Spoke holes

e*thirteen set the lacing for this hub. 4-cross on both sides.

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.

Side	Spokes	Length
Left (disc side)e*thirteen's pattern	14	303 mm303.3 worked out
Right (drive side)e*thirteen's pattern	14	305 mm304.5 worked out

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

Tension: the left spokes run at 66% of the right side's tension. Bracing angles 6.5° left, 4.3° right.

Weight: these spokes and alloy nipples come to about 190 g (about 208 g with brass nipples).

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.
