The Speed Tuned GRTR21d is a Gravel (GR) Tubeless Ready Disc rim that is still light enough for road. This rim is 22mm tall, 25mm wide, with a 21mm tubeless ready inner profile that's really strong, extremely stable, and at 480g, is still very weight competitive. You can run higher pressure road tube + tires on them, tubeless road, or wider/higher volume CX / Gravel type tires. They all work, and tire mounting occurs with minimal fuss. 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 secs. If you're into racing (Doh! not that kind of racing), training, or you simply prefer to buy really nice gear, this is your starting and finishing point. That's pretty straight forward.
We are building these wheels with Speed Tuned Super 6 2.0 MTB (Road 11 Spd) 6-bolt disc hubs, in either a 28 hole or 32 hole, three cross configuration. The rear hub features 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.
The Speed Tuned GRTR21d is a stellar wheel set option, in a field that's composed of some of the best aluminum alloy Road Disc and Gravel Disc rims ever. Given their level of performance, they are an unbeatable deal, (coupon codes here). We're not joking around here. If you don't have a lot of time to research all the rim options in the marketplace, if you don't have a lot of money, and if you can find this product page, maybe that's Magic.
