Sub 1000g wheelset for sub US$1000? - Ride report p12
Moderator: robbosmans
Well they have now been officially crash tested
Got my front wheel taken out by someone else and went down and smacked hard. Had to readjust my brakes, tweak the bars and very minor truing of the wheels. They barely needed any truing so I am quite impressed. No injuries, my first thought was, Dang... my wheels!
All good so far.

Just got home from a business trip last night. My tires were stretching on the rims all week. I put the first layers of glue on tires and rims and left them to dry overnight. Another coat today followed by installation and a day to cure. I'll ride them for the first time tomorrow.
Incidentally, with Carbon-ti skewers and a Token 12-23 cassette, the wheelset came in at exactly 1200 grams. That is still nearly 100 grams lighter than the Easton wheels I normally ride without cassette or skewers. Since these wheels will be for climbing I'm installing a pair of Vittoria Crono EVO 700x20C tires. They came in at 180 grams each. So total weight including tires will be under 1600 grams.

WOW! What a nice ride! I was only able to get an hour in, but I did it over some crappy, bumpy, rutted tarmac along the beach and didn't have any issues whatsoever. It could be the nice tires I am riding, but at 20mm I think they only contributed partially to the nice ride. These wheels are snappy, accelerate wonderfully, and brake at least es well as the Eastons I usually ride with. I'm currently using some Shimano composite brake pads but am looking at another alternative as these are nearly worn out.
While I admit, the finish on the brake track doesn't look quite as pretty as on some more expensive, name brand rims, I didn't feel any pulsing or abnormalities when braking. One thing I did notice as the wheels are so light is, when still in the stand, there is a noticable hop at the valve stem. The tire is smooth and even all around, as is the rim, but it seems the weight of the 42mm stem is enough to create a slight imbalance. I didn't feel it at all when riding but noticed it when the bike was hanging on the stand. In fact, both front and rear wheels came to rest valve stems down when left hanging on the workstand. I placed the speed sensor magnet opposite the valve stem on my rear wheel which seems to have mitigated things a bit. But after only a brief test ride this is the only nit to pick.
I've just come off 8 weeks of physical therapy for a knee injury so will be working back up to some longer rides and higher mileage. Stay tuned for a longer term ride report.

so going into my 5th month of usage (around 2500kms), heres my update on my sub1000$/ sub1kg build.
-never had to have the wheels retrued after the wheelbuild
-brake tracks are holding up well, no marks whatsoever on where the pads hit, just a slight shine compared to the bare carbon brake tracks (using mavic yellow by koolstop pads)
-soul (sean's) hubs are holding up wheel too! just increased noise from the freewheel compared to bnew, will repack with grease soon.
you cant buy fitness, but you can buy advantage.

farm_lim, what spokes did you use?

So today I got my hands on a brand new pair of Tune hubs, Mig-45 and Mag-150. I wasn't really shopping for hubs but couldn't pass them up. I got them for such a good price I can build another set of these wheels for under $1000.00 and I am certain they will be under 1000 grams.

New North American group buy here:
My apologies to the weight weenies elsewhere, I just can't handle the logistics of a worldwide group buy.

I've just ordered a set of these rims (20mm tubular) from that guy 'Henry' from Archtek Tech Co. I haven't got the rims yet, and I presume they'll take a few weeks to arrive but I'm planning ahead. I am going to use some American Classic hubs (Micro 58 front and 205 rear) and I plan to use DT Aerolite spokes.
Question is, what spoking patterns have people used? I was thinking about radially lacing the front, and going 2x on the rear. I imagine these aren't going to be the stiffest rims so I was considering doing the rear drive side radially and leaving the non-drive side 2x.
Any thoughts people?
Incidently, I will be using these for road racing, and I weight in at about 74kg. I'm 6'1" and reasonably powerful. These wheels are obviously intended as a climbing wheelset but I do want something I can still sprint on.
Cheers.

@Giles.
Ahh, if you want stiffer wheels maybe reconsider your hub choice. I know one person personally and have heard of a few others that have had negative experiences with the AC hubs (although perhaps they have a newer, more reliable model out). I am just skeptical looking at the NDS flange placement (could be moved out a country mile) and the seemingly tiny front hub diameter.

I take your point. The advantage of having the NDS rear flange set in a little is more equal spoke tension on the rear, hence more durabililty. The Micro 58 front hub has very low flanges but should be fine when radially laced I think.
Thing is, I'm planning on building these wheels as a second set of wheels (I have Lightweight race wheels). My priorities are 1. Light, 2. Cheap, 3. Stiff, in that order.
Althought the AM Classic hubs aren't ideal, I'm getting the pair for £100 and I can't get near the weight of them for that price. I was just hoping to make the most of them with the spoking pattern.
Thanks for your advice.
