rebuilding my trials wheel

it was built by that John Kavachi dude and i never knew the spoke size.it was laced 4 cross too.

it also was built with the longer nipples,not the smaller DT ones just so you know.

the spoke calc. thing was off by 3 mm for my latest doublewide/Profile wheel.

it was right on for a Alex 24/Profile wheel build last year.

I had to build my mod a 4X because 168’s (i think that’s what they were, maybe even shorter?) were so uncommon we couldnt get them without costom cutting. Heres the one my dad uses, it seems to be pretty acurate. http://www.bikeschool.com/spokes/

I did my Monty/Profile 4x as well.

Re: rebuilding my trials wheel

Leo,

I have just done a careful re-measurement of the rim. I used my digital
vernia and the instructions on the site and came out with 376.0 mm for the
ERD. Any idea where we could be wrong?

Sorry for the delay…

We at the Ordinary Bike Shop just built two of these. Profile hub, Alex DX32 19" rim, 4-cross. The rim ERD was 376, the spoke length was about 185mm, spokes were 14g of type DT Swiss. There are two views of the spoke interfaces here: http://www.unicyclist.com/gallery/view_album.php?set_albumName=albun41

The entire uni can be seen here: http://www.unicyclist.com/gallery/albuo07
