I like this solution but who is able to assemble rims with this magnetic nipples?
This kind of rim should be stiffer and... tubeless Very Happy .
If you know any shop who can mount this magical nipples, I will go for this solution.

What about a group for buying hubs, spokes and assemble all wheels?

The idea of pulling nipples through the valve hole by magnet or otherwise was mythbusted by me and my calipers in the wider 26" carbon wheel thread on Mtbr several weeks ago. It just won't fit. Trad drilling is the only way for the mountain bike rims. The exception is for the deep-dish road wheels, that will work because there is plenty of headroom.

News Flash:

Due to a PPP (Take it or be laid off) position being offered (their words) to me in Newport RI, I need to cancel my entire order.

I have about 45 days to move, maybe less........more to follow.

PB Matrix: Sympathies (or congratulations) on your new job. Good luck with the move, and I certainly understand about the need to cancel your part.

Eurotrash: Thanks for the heads up on the magnetic nipples SNAFU, I will stay traditional.

Is brass magnetic? I would assume there isn't enough nickel on a brass nipple to make it work either.

Check out JensonUSA for spokes. Their most expensive spokes are DT revolution and they $1.50. Double butted are about ten cents each less. Straight gauge are about a buck a spoke.

Sapim CX-ray. Mmm-mmm.

To use a magnet, you use a piece of old spoke or a steel insert made by Hozan. Nickel is non-Austinetic, it can't be picked up with a magnet.

Ok...now I'm confused. I thought that "austenitic" was only applied to steel, since that is the process of heating a steel to change the crystal structure, which renders it non-magnetic. Nickel is actually used in the process of making of some stainless steel, which is austenitic. So wouldn't "non-austenitic" imply that it IS magnetic??

Black hubs for me, not red ;-).
If they are red I will go for rims only ( red doesn't match my green and black flash)

Ya, I was trying to open a can...but John didn't go for the bait! I have to come clean...I had no idea what "austenitic" was, so I let my friend Wikipedia edumacate me. Always fun to put it out there...but not as much fun as if he had blasted me with a 2 page primer on metallurgy!

I started to... then I realized I made not one but two errors- first, the spelling, and second, I had my austenite and martensite flip-flopped in my head! When I think nickel, I'm usually thinking stainless. The time-temperature transformation is critical there, and the quick test is the magnet. I guess I've gotten rusty without my workshop to keep me sharp on metallurgy, pun definitely intended. So I cut bait! clown

"Hello Robert,

The order is being manufactured, and the 38mm wheelset is finished.
For 29er wheelset, it can be finished next week.

Thanks,
Nancy"

So, at least another week before the package ships.

Did you end up getting the 23mm wide 38mm depth clinchers? Very interested in these wheels.

The 29er wheels are 20mm depth, by 23mm outer (at least the two sets ordered were). The road wheels were 21mm width, 38mm depth, as I didn't realize they had 24mm depth.

I think Matt wanted to know about the road wheels.

I was asking about the road wheels. I see they are making a 23mm wide road wheel that is 38mm depth and 50mm depth. I am very tempted, but just don't know about the novatech hubs. What are your impressions? I am considering just getting the rims and building them in Chris King road hubs.

I asked Helen about the 24mm deep rims and she said they aren't advised for riders over 165 pounds.

I have a mixed impression on Novatec hubs. For a road bike, all that matters is that they roll smooth and are built to industry standard tolerances, right? Forget about replacement parts from a Chinese wholesaler, that is where the gamble comes in. Somewhere I read that they had Taiwanese bearings, but I also saw numerous photos of counterfeit German and Japanese bearings coming out of China... OK, so throw some Enduro or VXB cartridges in there and you probably have a nice hub. On the other side, for MTB use, I won't buy anything that isn't user serviceable, warrantied for M&W, and supported for replacement parts. At my weight and my riding style, I can't afford a catastrophic component failure. "Bearing" all of that in mind, most of our components have some Chinese aspect to them, and I have respect for the movement toward quality in Chinese manufacturing in the last few years.

That is what is making me lean towards picking up some King road hubs or DT240 and building them myself. I won't save money, but it will give some piece of mind. If I do get their wheels, I might do like you suggested and just throw in some Enduro bearings from the get go. I know a road wheel wont fail catastrophically with normal use, but replacing them when they are new is cleaner and you don't have to worry about creaky bearings in the middle of a long ride.

If you plan on replacing the hub, then I would just buy the rims from Light Bicycle, or perhaps also buying the spokes from them (I like the spokes, and Brian agreed to send me another 12 for the drive side replacement, free no less). Then build out a nice wheel; that is what I am doing for the rims I bought for the Mojo.
