Description
A sub 1300 grams carbon disc brake wheelset that can handle the rigors of road, gravel, and cyclocross that delivers the most reliable tubeless ready set-up? Yes, it is real, and the Stan's NoTubes Grail CB7 Pro Wheelset can handle up to 85psi with a 700x25mm tubeless tire or up to 50psi with a 40mm tubeless tire. If you prefer tubes the max pressure for the 25mm is 115psi. That makes the Grail CB7 Pro highly versatile for such a capable wheelset.
For NoTubes the key to building a great wheel starts with the rim. Lighter is better, tubeless ready is required, and the width determines the tire size range. The carbon CB7 Grail rims weigh in at 300 grams, so check off "light". The shallow bead socket tubeless (BST-R) for road, or higher upper pressure range takes full advantage of NoTubes 25mm tubeless tape and 35mm valves for an optimal set-up with sealant. The WideRIght concept was developed by NoTubes to ensure that rim widths are appropriately matched to tires size for optimal shape, use, and safety.
The 21.6mm internal width of the CB7 Grail Pro rim is designed for 25-40mm tires. Never exceed the maximum pressure rating of the tire and rim based on tire size, and use caution with low pressure set-ups to ensure that your seal is effective enough eliminate burping of air/sealant at impact. The rim technology is named RiACT. Obsessive attention to the shape of the rim and a proprietary carbon fiber lay-up process have resulted in a rim that absorbs radial vibrations and impacts while maintaining lateral stiffness, keeping your wheels driving constantly forward with less energy loss than other carbon rims. The more forward momentum your wheel and tire can maintain without deflecting off the ground and sending your energy upward and backward, the faster you move. RiACT carbon rims allow the wheel system to absorb more energy overall, offering levels of vibration damping and impact absorption never possible. The result is a rim that's both stronger and faster-rolling.... Read More
