The Stan's Grail MK3 rim features a 20.3mm inner width and 24.5mm deep, along with Stan's Legandary tubeless capability. The rim has been reworked slightly from it's predecessor so that you can now run higher pressure road tube + tires on them, lower volume with higher pressure tubeless road, or wider/higher volume CX / Gravel type tires at lower pressures. They all work well; tire mounting occurs with expected Stan's snugness. We build and ship these wheels with tubeless tape + valves installed, but you can always pop the valves out and run them with inner tubes. Valve remolval occurs via a simple loosening of the valve lock ring, takes about 10 seconds or less.
We're building these wheels with Speed Tuned Super 6 2.0 MTB hubs. The Speed Tuned Super 6 2.0 hubs feature 36 points of engagement, (10 degrees) via a 4x2 pawl free hub. The drive ring and pawls are overbuilt in terms of diameter, (drive ring), height, (drive ring + pawls), and materials, (quality stainless). Their bearing placement is proper, in terms of overall design meant to promote hub function and durability. Last but not least, these hubs offer both axle and drivetrain flexibility. The wheels only ship with one type of end caps and freehub installed, but additional options are available, allowing you to swap the wheel set in and out between bikes that might have different requirements.
In "stock" form, these wheels are built with DT Swiss Competition Double Butted 2.0/1.8/2.0 black spokes in a 32 hole, three cross configuration front and rear. DT Comp spokes offer legendary quality and performance. If you didn't know a thing about spokes, know that your wheels would come with a really top notch spoke product. That being said, we're offering a spoke upgrade option, in the form of Sapim DLight 2.0/1.65/2.0 spokes. There are two great spoke manufacturers in the world, DT Swiss and Sapim, (in alphabetical order). Essentially, you might be able to find a spoke product that approaches their quality, but you'd be hard pressed to find a company that makes a better spoke product than these two. All their spoke products, from straight gauge to their elliptically bladed and butted products, are all the best of the best. Sapim Dlight spokes will perform at the same relative level as DT Competition spokes, but will shave off approximately 75 - 80g from the wheel set.
