This is the rim we use on our four.zero wheelsets. Designed with the gravel rider in mind. With a wide hookless bead, this rim was built for gravel (though it works great for tubeless road as well). Available exclusively as a tubeless rim with 24 spoke holes. They weigh in at 410 (+/- 10) grams.

Recommended for tires 30 - 50mm. Maximum recommended air pressure is 65psi. Maximum spoke tension 135kgf. Recommended tubeless tape width is 25-26mm. No spoke washers required.

These rims come without markings or labels. Why? I think the better question is why not? Labels add weight, unbalance wheels, and add one more thing to the cost. We have tried stickers, paint, etc. Nothing is perfect and to be honest, we think the stealth look is best. If you want a label, let us know and we will send some. Free advertising for us. But we trust in our product and don’t think you need that!

Please note. These rims have hookless beads. You must use tires that are designed for hookless beads or you risk blowing the tire off the rim. In addition, we recommend no less that a 30mm tire and no more than the manufacturers recommended tire pressure for tubeless.
