We The People and Investment Cast Innovation Feb 1, 2011


In the world of framebuilding, just muttering “investment cast” will get you some nasty looks. But in the world of mass-production, it’s an every day technology. That is, until you start to manufacture entire headtubes. Now I know this is relatively old news but it’s the first I’ve heard of it. We The People have started to investment cast their head tubes and seat tube clusters, specifically on their C.R.E.A.M. frames.

Check out more below.


You can see all the detail shots and read up on their theories here. Don’t forget to check out their frames, in all their production-quality glory here. Honestly, this is one of the most creative uses I’ve seen in regards to a mass-produced frame. Very innovative indeed. Many thanks to Dr. Tony Fast for the heads on this one.

    Prolly, has anyone attempted to make a cast iron road bike? tlak about the antithesis of lightweight!

    Interesting. This reminds me of an old schwinn traveler frame I have kicking around; it’s headlugs were actually cast onto the headtube as a single piece.

    @ bran. Uhhh, investment casting is a manufacturing method… this, by no means alludes to cast iron material. Of course the parts aren’t iron, haha. I’m sure the parts will be comparable in weight.

    My buddy has the We The People Warriors frame which has investment casting where the dropouts meet the seat/chain stays. I always thought it looked pretty cool and seems pretty solid

    Trek used investment cast seat tube clusters and bottom bracket shells on some of their racing frames in the early ’80s.
