Drop some knowledge on me!

I am relacing a set of Peregrine 48's. I. Measured the spokes at 7 1/4 inches long. I am purchasing the spokes from Porkchop. Does anyone know the dimension or size I need for these. I believe I need 184's.  Thanks for your help!

Re: Drop some knowledge on me!

7.25 inches = 184.15 mm

I think you are spot on.

Make sure you measure the front and rear separately. They are not always the same length.

If in doubt think about dealing with Danscomp - they have people you can talk to and will assist in getting you exactly what you need (and many more options).

Make sure you are measuring from the center of the head to the end of the spoke. I just built some HP 48's and the spoke length was 182mm for both front and back.

Also measure both rear spokes. Usually the drive side will use a shorter spoke.

I've always said this too but others started a debate saying all hub are centered. Coco is right. I have measured and 80% of my hubs have offset.


Ban me! Please!

Not confusing at all. You have the original spokes, correct? If so, just measure the length of the ones used for the front wheel, and then measure the ones from the rear wheel. In all likelihood they will be slightly different sizes.

If you don't have the spokes to measure, then yes, I would take them to my LBS - they have an ultimate set of tools lol

I've been building my own wheels for almost 20 years. Most wheels have an offset but sometimes it is very minimal and when using a double wall rim, you can get away with using the same size 8 times out of 10. Most of my hubs I use have a higher flange (Profile mini cassette for example) on the drive side.

When in doubt, a good bike shop is the way to go for wheel builds. It may cost you but it should be done properly after it is all said and done.

Bring in the hub and rim and they can measure it all up for you.
