Waw, that’s cool.
You know what, you should do this also for skateboard’s trucks.
Because most of the time, when you skate and grind, they don’t everlast.
Peace!

Nice work, if I knew you guys are making this, I won’t spend the same money on my Thomson stems.
btw, do you have the photos of side screws as well?

Sweeeeeeeeeeeet!!!!!!!!

woah! Looks so mice! Great work guys!!!

if i had a bike i would want it to look just like that.

AWESOME. Can’t wait to see one in person.

This is really sick….why are you not patenting this? you need to protect your intellectual property, silly artists.

The top of that block looks like a nice place to mount an iphone/electronic device. It’d be cool if you facilitated that with some kind of holder. Nice work t-pain

@RyMo I suggested the same thing, it would be perfect for mounting a camera!
Nicely done guys. Looks great!

Stuart?

ha. no. china.

Wow! this is amazing… Thank you so much for licensing this under the CC-BY-NC-SA. I think it is great that you share your design with people in this manner. Keep up the good work!

so you guys are in bed-stuy?
whereabouts? we should ride!

cw lives in bed-stuy. t is currently in an apt crisis. our work space is in greenpoint. Let’s ride! We’re out there all the time.

CC licence? It’s a common BMX design, and probably already PD, and likely unpatentable because it’s so simple.

@spiny norman A patent issued by the government conveys the exclusive right to produce the product for a limited time, that is, it protects your “intellectual property”. A patent really has nothing to do with a license. The license simply covers their work (i.e. the two files that are available for download). Read the CC-BY-NC-SA to better understand its terms.

Its cool looking, but you’ll stab your knees on those sharp corners…

yea. like we said, it’s not for everyone. we’ve been riding them for a while now and haven’t stabbed my knees on them. yet. fingers crossed.

Is this a joke? You guys can’t seriously be thinking that this is a “designed” stem. Its a chunk of aluminium with 2 holes in it. And even then it is a rip off bmx stems. At least those are engineered to be light- 240g for Primo Aneyerlator. Go do some “tricks” on your fixies and please leave bike parts design to professionals.

No, it’s not a joke. Yes, it’s a chunk of aluminum with a 26mm and 1-1/8″ holes in it. We love bmx stems that are engineered to be light. But we also like our heavy 1 pounder. I don’t know how to do any tricks on our fixies so I won’t go do any, but thanks for the suggestion. We’ll keep designing bike parts because we are professionals. :)

Weight: 501.8 grams? Too heavy!

delectable.

but does it blend?

NO! but it juices

Next has to be the blockhead seat post clamp. Get to it guys.

we’re on it.

neeeeeeat! wait, can it be mounted onto my bike http://itp.nyu.edu/~ml1949/2IN1.htm :D

What kind of headset do the bikes in the pictures have for the stem?

The white leader frame has a fsa carbon integrated headset. The black 183rd St. frame has AheadSet.

Bell & Ross called, they want their brand and identity back

Ha ha. Ok they can have it back. Which part is it that bothers you? The & between a bunch of letters? Or that it’s two names?

Nice one!

I’m no weight weenie, but that is seriously heavy

t, what kind of apt crisis?
i’m moving out in the next month some time and might stay in bedstuy, not sure. riding often between stuy + grnpnt, perhaps i ride by the shop? anyway, i’m def on the lookout for something live/work so perhaps something to explore.

kylej…ride by our studio anytime. send us an email first to make sure we are there. cwandt [at] cwandt [dot] com

Looks cool, but it’s a plain overpriced bmx stem :P

If it really took you a month to find a machinist to make this, it is probably because the “0.01mm tolerance” listed is absurd. Nobody wants to deal with tolerances that tight when there is no reason for them. If you changed that to “0.1mm” (or even larger) you’d have an easier time finding somebody to make these. And with no discernible loss of quality, since the amount of flex that the clamp design affords would easily take up any tightness or slack.

yup. you’re right. that’s a typo. ha. the tolerances are .1mm.

hi guys, cool stem…wondering what skin/theme this cw&t site uses…assume its wordpress?
thanks.

thanks et. we used and modified swiss-magazine wordpress theme by Upstart Blogger.

Oh yeah!! will be ordering one of these when I’m a bit less poor! wonderful thought, love the name…

I think it looks great, very minimalistic (kinda like a fixed gear).
I built one about 8 years ago just like it except mine is 6061-t6 instead of 7075.
I use the aheadset as well and I used black grade 8 socket head cap screws.
What is the small relief where the bars clamp in for? More effective clamping?

I know a machinist that can make these all day long- he used to make parts for me when I worked as a designer in the bike industry. Let me know if I can help.

cool! the little groove is for the brake cable, if you want to tuck it under the handlebar for the front brake.

Beatiful! Please don’t do anything iPhone (or similar crap) related with it!

Truly amazing. A stem/brick that not only stands out from the crowd but weighs in at only half a kilo! You should make a 31.8 clamp diameter version machined out of pig-iron. That´d make some waves. Keep up ye goode worke in the name of “My Little Pony” style fixie one-upmanship.

please please i want to buy,but i’m in indonesia. can i buy it and shipped to my country
it very please

it is fixed. we can now ship to indonesia! let us know if there are problems.

How come you don’t have the option to ship to Australia? I want one!

Australia, just added. Knog rocks! we have you on our bikes.
