Nextie Gravel carbon rim
The Nextie Gravel is a full carbon fiber rim for gravel and all-road riding on 35 to 50mm tires, with the wider bed that lets a big tire hold its shape at low pressure. Premium is Nextie's all-round layup: a little more material than Supreme for a rim that shrugs off rock strikes and seasons of use. Nextie designs and molds the rim; ProWheelBuilder is an independent wheel builder in Georgia, not the manufacturer. We build the rim into a complete wheel: pick the hub, spokes, nipples and lacing in the configurator and it ships laced, tensioned and trued.
Sizes, weights and prices
10 sizes in 700c. Rim weights are Nextie's published figures per size; ERD is the effective rim diameter we cut spokes to.

What the designations mean
Every size in the list carries Nextie's own series code so you can tell the profiles apart. Here is what they mean.
| Supreme | Nextie's lightest layup - the least material that still meets the rim's strength target. Choose it when grams matter most. |
|---|---|
| Premium | The all-round layup: a little more carbon than Supreme, for a rim that shrugs off rock strikes and seasons of hard use. |
| CGX | Premium gravel, 25mm inner - road-gravel crossover for 32-40mm tires. |
| RGX | Premium gravel, 38mm inner - the widest gravel bed for 50mm-plus tires. |
Material and construction
Every size is molded from carbon fiber in Nextie's Xiamen factory, in a UD (unidirectional) weave with a matte finish. Premium is Nextie's all-round layup: a little more material than Supreme for a rim that shrugs off rock strikes and seasons of use. The rim bed is tubeless-ready, and a Nextie Gravel rim is stiffer laterally than an aluminum rim of the same weight, which is what makes a light carbon wheel feel precise under power. Nextie rates these sizes for a maximum system weight of 138 kg; 140 kg; 143 kg; 145 kg; 148 kg; 150 kg; 153 kg; 154 kg; 155 kg; 158 kg; 159 kg; 160 kg; 165 kg; 169 kg; 173 kg (rider plus bike and gear).
Weight
Weights run from 330g for the 30MM DEEP CGX (25MM INNER) to 500g for the 60MM DEEP RGX (38MM INNER). Rim weight is rotating weight at the outside of the wheel, so every gram saved here is felt more than a gram saved on the frame. Inner widths of 25mm, 27.5mm, 29mm, 32mm, 38mm decide the tire: wider beds let a big tire hold its shape at low pressure.
Value
Nextie molds its own rims and sells factory-direct, with no distributor or brand-marketing margin built into the price. The material and the construction are the same full carbon fiber, UD layup and tubeless-ready bed found on rims that cost two to three times as much from the big-name brands - the Nextie Gravel simply skips the layers of mark-up between the mold and your wheel.
Because we sell the Nextie Gravel only inside a wheel we build, that saving carries through the whole wheel: we lace it to the hub you choose, cut spokes to the measured ERD of the exact size, tension and true it by hand, and stand behind the build. You end up with a hand-built carbon wheel at a price most brands ask for the rim alone, and the current per-size price is always shown live in the configurator.
How we build it
Choose the size and wheel diameter, then a drilling (24h, 28h, 32h, 36h), and the configurator only offers hubs, spokes and lacing patterns that can actually be built with that combination. Sizes that are not made in a given drilling or diameter are struck through rather than hidden, so you can see the whole range. Use the Custom Wheel Program to start from this rim, or send us a rim you already own with the supply-your-own option.
Build it with us
We build this rim to order. Open the Custom Wheel Program with the Nextie Gravel Carbon Rim already selected and pick the parts around it; it is offered for gravel and road disc, touring and tandem and e-bike builds, and the configurator will not let you assemble a combination we would not build.
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.
Warranty
Manufacturer's warranty. Nextie warrants this product against defects in materials and workmanship. The duration, conditions and claim process are set by Nextie and can change without notice, so ask us and we will confirm the current terms before you buy.
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.
Full terms are on our Policies & Warranty page.
Nextie Gravel questions
Is ProWheelBuilder the manufacturer of the Nextie Gravel?
No. Nextie designs and manufactures the rim. ProWheelBuilder is an independent custom wheel builder in Georgia: we buy the rim from Nextie and build it into a finished wheel to your spec.
Can I buy the Nextie Gravel on its own?
No. We supply Nextie rims only as part of a wheel we build, so every rim is laced, tensioned and trued here before it ships.
Which spoke count should I choose?
It depends on your weight, terrain and the hub, not on the rim alone. The configurator recommends a count from your bike type and rider weight, within the 24h, 28h, 32h, 36h this rim is drilled for.
Is the Nextie Gravel tubeless-ready?
Yes. Nextie builds the rim bed tubeless-ready; we tape and fit a valve when you choose the tubeless option in the build.
How long will the wheel take?
Build time comes down to parts availability rather than bench time. The estimated ship date is shown in the configurator before you check out.
