"Blockhead Stem is the sturdiest stem you’ll ever meet. A solid chunk of aluminum machined with sharp edges and corners, this stem is not for everyone. Ride it at your own risk.
Blockhead stem's design is licensed though the creative commons. We're fabricating and selling them, but we're happy to have other people modify the design and find their own fabricators too. It's a solid block of 7075 aluminum. It's heavy, but it's indestructible. Please help us get the word out.
The first 5 people to purchase the stem from us can use the discount code, agoodword, to get 25% off."
