Give credit where it’s due. We actually want you to go find your machinist buddy and see if he or she can make it for super cheap. We spent about a month searching for a quality machinist that can produce them on demand. If you find a better machinist please share.

  1. 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!

  2. 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?

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

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

  8. 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

    Posted August 17, 2009 at 11:11 am by RyMo
  9. @RyMo I suggested the same thing, it would be perfect for mounting a camera!
    Nicely done guys. Looks great!

  12. 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!

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

    Posted August 18, 2009 at 8:57 am by kylej
  14. 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.

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

  16. @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.

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

    Posted August 18, 2009 at 7:01 pm by Tom
  18. 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.

    Posted August 18, 2009 at 8:22 pm by cwwang
  19. 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.

    Posted August 19, 2009 at 9:23 am by anton
  20. 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. :)

  24. NO! but it juices

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

    Posted August 23, 2009 at 3:16 pm by Kyle
  29. The white leader frame has a fsa carbon integrated headset. The black 183rd St. frame has AheadSet.

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

    Posted August 24, 2009 at 11:22 am by o
  31. 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?

    Posted August 24, 2009 at 11:56 am by cwwang
  32. Nice one!

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

  33. 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.

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

    Posted August 27, 2009 at 9:13 am by ahoge
  36. 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.

    Posted August 27, 2009 at 6:49 pm by Mark
  37. yup. you’re right. that’s a typo. ha. the tolerances are .1mm.

    Posted August 27, 2009 at 7:24 pm by cwwang
  38. hi guys, cool stem…wondering what skin/theme this cw&t site uses…assume its wordpress?
    thanks.

    Posted August 30, 2009 at 6:02 am by ET
  39. thanks et. we used and modified swiss-magazine wordpress theme by Upstart Blogger.

    Posted August 30, 2009 at 6:38 am by t
  40. Oh yeah!! will be ordering one of these when I’m a bit less poor! wonderful thought, love the name…

    Posted September 1, 2009 at 7:01 am by Karl
  41. 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?

    Posted September 1, 2009 at 12:17 pm by tim
  42. 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.

    Posted September 1, 2009 at 8:35 pm by Honus
  43. cool! the little groove is for the brake cable, if you want to tuck it under the handlebar for the front brake.

    Posted September 1, 2009 at 8:51 pm by cwwang
  44. Beatiful! Please don’t do anything iPhone (or similar crap) related with it!

    Posted September 18, 2009 at 7:01 am by geistgesicht
  45. 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.

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

    Posted October 7, 2009 at 2:35 am by t
  48. How come you don’t have the option to ship to Australia? I want one!

    Posted December 15, 2009 at 9:08 pm by Elliott
  49. Australia, just added. Knog rocks! we have you on our bikes.

    Posted December 15, 2009 at 9:48 pm by cwwang
  50. will you be releasing the blockhead with built in brake lever any time soon, i want one rather badly.

    Posted March 25, 2010 at 1:22 am by leo
  51. YES! We’ll be taking preorders next week.

    Posted March 25, 2010 at 8:56 pm by cwwang
  52. Wow. Ugly, heavy and dangerous all at the same time! I’m also curious as to how you know that it’s the “sturdiest stem you’ll ever meet”? Why? Because it has shitloads of material in areas that it’s not needed? Does that make it sturdier? Or just dumb and poorly “engineered”? I’m a professional designer too, the difference is that you just suck at it.

    Posted April 5, 2010 at 11:20 am by Derek
  53. Hi D! We’re sorry it doesn’t fit with your taste. sad face. tear.

    Posted April 6, 2010 at 5:19 am by cwwang
  54. hey i want a 1 inch one please?????

    Posted April 27, 2010 at 9:57 pm by darwin
  55. we’re planning on making a bunch of 1 inch versions in our next batch. We’ll let you know when they’re available.

    Posted April 27, 2010 at 9:59 pm by cwwang
  56. yo. Was wondering if it’ll fit on a charge plug? the stem is 28mm so will it be too big? if not I need to have one of these! They’re so stylish.

    Thanks,

    Carson

    Posted July 17, 2010 at 11:01 am by Carson
  57. It should fit on your bike. If your handlebar diameter is less than 28mm (i think yours is 25.4mm) you can find adapters (aka shims) on ebay to get it to fit.

    Posted July 18, 2010 at 10:42 am by cwwang
  58. A friend is currently machining two of these out of the same piece of aluminum as I type this. One for me and one for a pal. I am stoked.
