Hope Fatsno rear 170 QR / 177x12 spoke length

J-bend, 32 hole. Flange diameter 57 mm left and 57 mm right, centre to flange 45 mm left and 37 mm right. Pick your rim in the calculator for your exact spoke lengths.

Rim

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

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

How to measure ERD yourself
gapspoke + nipple,screwed on flushERD = spoke + spoke+ gap

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

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

Lacing

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.

Spokes

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

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

Spoke lengths

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

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

Tension: the left spokes run at 78% of the right side's tension. Bracing angles 5.7° left, 4.5° right.

Weight: these spokes and alloy nipples come to about 182 g (about 200 g with brass nipples).

Will my spokes fit?
Ping tuner: what each side should sound like
B4, about 490 Hz at 86 kgf
C#5, about 561 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

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.
