Velocity Atlas Disc Brake Rim
The Velocity Atlas is the rim we build when the wheel has to carry a lot: loaded touring, tandems, cargo bikes and heavy e-bikes. The Atlas has extra-thick sidewalls, double eyelets at every spoke hole and a section that does not care how much you put on the rack. Velocity extrudes and finishes it in the USA, and it has been the touring rim of choice for long-distance riders for years.
This page covers the Velocity Atlas Disc Brake Rim in 700c, 650b, 26in. The Atlas is not sold bare. You choose the hub and the rest of the build in the configurator, and it ships from our shop in Georgia laced, tensioned and trued by hand.
Design and construction
The Atlas is a double-wall aluminum rim, 19.8mm wide inside, with walls thicker than any other Velocity road-size rim and double eyelets that spread nipple load through both walls. That combination is what lets the Atlas take the very high spoke tension a loaded wheel needs without the spoke bed cracking. The rim-brake version has a machined sidewall with plenty of material to wear; the disc version has a plain sidewall.
The factory recommends 110 to 130 kgf spoke tension, and the Atlas is happy at the top of that range. It takes 28 to 50mm tires with tubes; it is not a tubeless rim.
Every Velocity rim is extruded, drilled and finished at the company's own factory in Jacksonville, Florida, and that shows in the details a builder notices: the spoke holes are drilled to suit the wheel, the joint is clean, and the ERD we measure matches the one on the box. The color range is the other reason people ask for the brand by name; anodized and powder-coated options come and go, and the ones in stock are listed in the configurator so you can match rim, hub and nipples.
How it rides
An Atlas wheel is steady. It does not flex under a loaded bike on a rough road, it does not go out of true after a week of dirt-road touring, and the brake track lasts. It is heavier than a Dyad or Chukker, which matters less than you would think on a bike that already weighs forty pounds loaded.
We build the Atlas with 36 spokes for touring and cargo and 40 or 48 for tandems. It is the Velocity rim we recommend for anyone who has broken a lighter rim under load. Riders who have toured on lighter rims and had a spoke bed crack under the rear rack are the ones who ask for the Atlas by name, and it has never let one of them down in our experience.

This listing
This is the 700c, 650b, 26in listing of the Atlas, 32h, 36h, 40h, about 620g, 19.8mm inside, 18mm deep, disc. Pick the size that matches your frame; the profile and construction are the same across the range.
The disc version of the Atlas has no brake track, so the sidewall is a plain extrusion that saves a little weight and never wears; it is the one to choose for any disc-brake frame. The rim-brake version, listed separately, has a machined sidewall.
Sizes, fit and compatibility
The Velocity Atlas Disc Brake Rim comes in 700c, 650b, 26in and 32h, 36h, 40h drilling, in rim-brake and disc versions; check the name on this page. We build the Atlas on Velocity Standard and Tandem hubs, DT Swiss 350, Shimano, White Industries, Phil Wood and Son dynamo hubs, usually with DT Champion or Sapim Strong spokes and brass nipples.
Tire range on the Atlas is 28 to 50mm. Pick touring, tandem or e-bike as your bike type in the configurator and it recommends a spoke count and lacing pattern.
Put it in a custom wheel
Build a custom wheel around the Velocity Atlas Disc Brake Rim — the link drops you into our Custom Wheel Program with this rim pinned, ready for you to choose the rest. It is set up for gravel and road disc, track and road single-speed and touring builds.
Spoke head is decided by the hub, not the rim: this rim builds equally well with J-bend or straight-pull spokes, and the configurator only offers the spokes that match the hub you pick.
What Velocity says about testing
Velocity USA rolls, drills, anodizes and builds its aluminum rims at its own factory in Grand Rapids, Michigan; Velocity states the extrusion comes from Profile Precision Extrusions in Arizona. Production moved there from Jacksonville, Florida beginning December 2016. Rims are sleeve-joined: a piece of extrusion shaped to the rim's inner cavity is bonded in and the join heat-treated to set the bonding agent, then the rim is drilled, cleaned of swarf and anodized in Velocity's own tanks. Spoke holes are drilled at an exit angle of around 4 degrees, alternating flange bias at every other hole.
Velocity states that "Rims and wheels are checked for quality at every step of our process" and that it tests rims on an in-house load machine it calls the "Killdozer" "so that we can simulate a larger rider and calculate how many spokes result in a sturdy, quality wheel." Its spoke-count guidance by total rider-plus-gear weight is 200-229 lb: 32 spokes; 230-259 lb: 36; 260-300 lb: 36 front / 40 rear. Velocity recommends building to between 110 kgf and 130 kgf spoke tension and builds its Clydesdale wheels to 120 kgf.

Building it at ProWheelBuilder
Velocity USA makes the Atlas; ProWheelBuilder is an independent wheel builder in Georgia, not the manufacturer. Every Atlas wheel we build gets spokes cut from the rim's measured ERD, is tensioned in stages with a gauge to the top of Velocity's range, stress-relieved and trued before it ships.
In the configurator you will only see parts that fit this drilling; combinations that are not made are struck through, and the price updates as you pick.
Warranty
Velocity's warranty. Velocity warrants its rims against defects in material and workmanship for the life of the product, repairing or replacing at its option. Normal wear, accidents, misuse, improper assembly and poor maintenance are excluded.
ProWheelBuilder. If we lace this into a wheel for you, that wheel also carries ProWheelBuilder's own one-year warranty, which covers broken spokes regardless of cause and all wheel-related labor, including truing and rebuilding, for a year from purchase. Where a rim or hub is covered by its maker, we make the manufacturer's claim for you and coordinate it; where it is not, we offer an eligible replacement rim or hub at 25% off current retail. Shipping to and from us is the customer's. This cover does not extend to wheels built from components you supply yourself.

Atlas Disc Brake Rim questions
What tire width suits this rim?
At 19.8mm inside this is a road width. It suits roughly 25 to 32mm tires, which is where most road bikes now sit, and it will run a 23 if you still want one. Go much wider than 32 on this rim and the tire starts to balloon above the sidewalls and squirm when you lean on it.
Is the Atlas tubeless?
No. The Atlas is a tube-type rim built for load, not tubeless. For a tubeless touring rim look at the Velocity Cliffhanger.
Atlas or Dyad?
The Dyad is a lighter touring rim for moderate loads; the Atlas is the heavy-duty one for tandems, cargo bikes and fully loaded touring.
What spoke count should I use?
36 for touring and cargo, 40 or 48 for tandems. The configurator recommends from your bike type and weight.
Is the Atlas good for e-bikes?
Yes. Its thick walls and double eyelets suit the extra weight and braking loads of an e-bike; pair it with e-bike-rated spokes.
Is it tubeless-ready?
Velocity lists the Atlas Disc Brake Rim as clincher. Ask us about tubeless conversion if you need it.
Which spoke count should I choose?
It depends on your weight, terrain and the hub, not the rim alone. The configurator recommends a count from your bike type and rider weight, within the drillings this rim is made in.
