Then came tubeless, and suddenly, it was the tire/rim interface that radically changed. The G27 features a 27mm internal width that is intended for pairing with tyres 42mm with 55mm/2.0 tyres being the target tyre width for this rim.Due to the straight sidewall/hookless design of this rim and inherent high volume design, it is important to understand that not all tyres are created equal and for that reason one should pay special attention to the pressure ratings of both the tyre and the rim.G23 Max pressure for a 32mm tyre = 60psi/4.1barG27 Max pressure for a 42MM tyre = 40psi/2.75bar, Models:M525, M630, M635, M640, M685, M730, M735, M735E, M930, AM30 Tubeless Rim Type: Hookless/Straight-Sidewall Inner-Tube Compatible: Yes, Only with Tubeless/Tubeless Ready Tyre, Inner Rim Width Dimension:M525 = 25mmAM30, M630, M730, M930 = 30mmM635, M735, M735 E = 35mmM640 = 40mmM685 = 85mmTyre Size Range Suggestions:M525 = 2.12.4AM30, M630, M730, M930 = 2.32.6M635, M735, M735 E = 2.52.8M640 = 2.83.2M685 = 3.84.5.

Over the last year, weve worked with the engineers from both companies to ensure the full compatibility of our tires with their rims. Built upon over a decade of carbon wheel crafting experience, the Foundation 45 brings our knowledge and technology to the masses. We recommend building up the rim bed with extra layers of tape, but there is only so much you can do before the rims sidewalls arent tall enough to hold the tire securely. When you mount your tires, pay attention to how the tire goes onto the rim: If the fit is a little tight as the tire seats, then the diameter is correct. Two that come to mind are Velocity Atlas and SunRingle Rhyno Lite, both available in 36h for ISO 559 wheels (my preferred size). enve Built upon over a decade of carbon wheel crafting experience, the Foundation 45 brings our knowledge and technology to the masses. Seems pretty sloppy. What about aluminum rims? Our supple high-performance tires dont have the same casing stiffness as the mtb-derived gravel tires you mention. Because of this process, our spoke holes are capable of maintaining higher spoke tensions, greatly reducing the risk of spoke pull-through and the need to constantly true your wheels. It also indicated that other wheel makers are seeing similar problems with the tires. In both instances, the tires were installed tubeless and seated perfectly fine, but they blew off the rear rim totally inadvertently while riding, one as far out as around 500 miles from initial installation.

DT-Swiss TK 540 I did offer to bring my Barlow Passes and M50s over to you when I was having the burping problems and again after the blow off (Im local to you). enve To clarify, the 2 mm tolerance with hooked sidewalls is in diameter, so its a tolerance of 1 mm on each rim bed.

Because carbon fiber gets its strength from continuous fibers, ENVE routes the fibers around the hole without cutting them, increasing the strength of each spoke hole. Hookless/Straight-Sidewall Design-Tubeless performance depends on the tire maintaining a light press-fit with the rim on the bead seat diameter. Tubeless tires are an emerging technology. I am a larger and heavier rider. Id like to test (and measure) a few more wheels before saying anything definitive, but it seems fine. enve All rights reserved, Auburn Cord Duesenberg Museum, Auburn, Indiana, Erik's first e-bike-only store is also its first Arizona location, OKAI shows new fat-tire e-bike model at Big Gear Show, State Bicycle Co. and Corona Announce Cycling Collection.
