I was hit by a car and my front wheel was run over. The rim and about 10 spokes where ruined, but the hub seems fine, so I'll reuse that. The weight weenie bug has hit me now that I need to buy some new parts (replaced the stem, bars, and fork too from the accident), and I would like to run less spokes.
The wheel was an H+son rim laced with straight gauge spokes to a dura ace 7600 hub, so it was quite heavy, 1140g for just the front according to my postage scale. I have a few options I'm looking at and am wondering what kind of advice within those options you guys can give.
I'm going to replace the rim with a kinlin xr-270, which will drop the weight by itself is 180g.
Buying much better Sapim laser spokes which drops the weight 110g.
And the kicker, I want to lace the front 24h, which drops another 50g and means buying less spokes lol.
So yeah, a 36h hub laced to a 24h rim. I know it's been done before, by quite a few people. Sheldon Brown has an example of one on his site. The wheel was laced 3 leading 3 trailing, and I think the general pattern can be kept while just removing some of the spokes in it, making it a 2 leading 2 trailing.
The original 3 leading 3 trailing:
If I were to remove the outside two spokes from the design to fit a 24h rim:
If I were to remove the inside two spokes instead:
Or I could simply use a radial lace, although I'm hesitant to relace a hub radial after it already has about 4k miles on in another pattern, since I know relacing a hub in a different pattern than was originally used on it it a nono, and radial lacing a hub is a questionable, and lacing a hub skipping 6 holes on each side is a questionable. nono+questionable+questionable = probably avoid that.
As far as spoke length, 2 leading 2 trailing uses 2x spokes. I can't quite wrap my head around how having a few more holes in the hub would change that length. Would it make the spokes a few mm shorter on the skipping outside version since they are slightly closer to the rim where they lace, and inversely a few mm longer on the skipping inside version since they are slightly further away?
And which version seems like it would stress the hub less? I'm inclined to believe the skipping outside holes version because it gives some empty space on the outside of the pattern, so the tension of those last spokes can be spread out over a bit more flange. Does anyone see any real issues doing this?
Edit: sorry everything looks so dirty. I've been waiting for a reason to clean the hubs and spokes. Since I'm getting a fresh rim and spokes both in silver, I'll strip the paint off the hub and polish it again for a clean look once more. Don't worry, the bearings are kept in very good condition even though the outside is painted and dirty. I clean those things inside like 4-5 times a year.
