I was all set to go to work last night...when I heard that today was the Kuhio Day State HOLIDAY!!! What a surprise! I was this // close to going to work this morning...
Anyways, put the day off to good use and spent about 3 hour building my first rear wheel...and although if took a LONG time, it was satisfyingly fun!
Here it is with the 6 pull drive side spokes laced. I took a long time deciding whether to lace the pull spokes heads out or heads in. But, after reading the Sapim site and seeing they recommended the pull heads in, that's the way I built it. From what I've read it's supposedly a better bracing angle and I knew I wouldn't have any clearance issues with my rear derailure since my current Open Pros were built pull spokes head in. My only issue was that the Dura Ace hub I was reusing was laced the other way originally...oh well...
Not knowing exactly how to do a 2x rear lacing, it was a good thing I took some pictures of the original 650c build so I had something to follow. Not as difficult as it may look or sound...
All built and trued up!
Took a really long time to true it up as I didn't have all the "proper" tools (only a Park spoke wrench) and was doing it all by feel. But, after slowly tightening left and right, things really started to fall into place and I think its really a tight build...a LOT tighter than my front wheel. I will be tightening up my front wheel again for sure...
For this wheel, I used one of my old frames as a truing stand. For my front wheel, I used an old steel fork I had laying around. Also used plain old Phil Wood grease on the threads and the nipple seats. I read that if you lace it up really tight, you shouldn't need any Spoke Prep...we'll see...
One thing I remembered today (and should have know yesterday) was that to prevent twisting the spokes 360 degrees while tightening, I needed to push on the rim to detension the spokes, made truing much easier - versus almost damaging the spokes trying to hold it with a cresent wrench...duhhh...
Also, on this rear build, I decided to "debur" the nipple seats using the ball-end of an allen wrench...not sure if it was really needed, though, I read it was good to do...
Took some weights:
Rear DA 7700 24h Hub: 310g (no skewer)
Kinlin 24h 30mm Rim: 460g
24 Sapim CX Ray Spokes: 115g (278, 280)
24 DT Alloy Nips: 10g (yeah...chancing the alloy on the DS)
24VeloPlugs: 5g???
TOTAL REAR WHEEL: 900g
Front DA 7700 24h Hub: 120g (no skewer)
Kinlin 24h 30mm Rim: 460g
24 Sapim CX Ray Spokes: 110g (272)
24 DT Alloy Nips: 10g
24VeloPlugs: 5g???
TOTAL FRONT WHEEL: 705g
TOTAL SET: 1605g
Wow...pretty light and looks super trick...not bad for a set of 30mm deep aluminum rims w/ Dura Ace hubs...can't wait to ride it!!!
