Convergence We Are 1 Whisp Carbon Rim
The We Are One Convergence Whisp is the cross-country race rim in the Convergence range, laid up and molded by hand in Kamloops, British Columbia: 29mm inside, about 380 grams, in the shallow Convergence section with its alternating wall curves and ZRT composite films in the lightest layup in the range. It is a race rim that is wide enough for modern 2.25 to 2.4in cross-country tires and tough enough, thanks to the Convergence profile, for down-country riding. 29in only, lifetime warranty.
This page covers the Convergence We Are 1 Whisp Carbon Rim in 29in. The Whisp is sold here only inside a wheel we build: choose the hub, spokes and nipples in the configurator and the finished wheel ships from Georgia, laced, tensioned and trued by hand.
Design and construction
The company does something almost nobody else does: it lays up every rim by hand in its own factory in Kamloops rather than buying molded rims from Asia, and the Convergence profile is the result of being able to iterate on its own tooling. The rim wall is not a smooth arc but a series of shallow curves that alternate at 7.5 degrees to match the angle each spoke leaves the rim, which stiffens the spoke bed and lets the rest of the section stay thin and compliant. ZRT films in the layup add impact strength without adding weight. The bead is hookless and tubeless, the nipples external, the spokes standard J-bend.
How it rides
A Whisp wheel is light and fast and, like every one of these rims, comfortable. The shallow section gives over roots and keeps the tire on the ground, the 29mm bed supports a 2.35in race tire at low pressure, and the wheel accelerates like a rim that weighs 380 grams should. For trail riding the Sector is tougher; for cross-country and marathon racing, the Whisp is the We Are One rim we recommend.

This version
This version is the Convergence Whisp in 29in, drilled 28h, about 380g, 29mm inside, 21mm deep, disc. Where the same rim is sold in another size or brake type, that is a separate listing with its own page.
This is the disc-brake Convergence Whisp: plain sidewalls, no brake track to wear, a touch lighter. It fits any disc-brake bike and it is the version most of our customers now build; the rim-brake version is a separate listing.
Sizes, fit and compatibility
The Convergence We Are 1 Whisp Carbon Rim comes in 29in and 28h drilling. It is a disc-brake rim. We build the Whisp on Industry Nine Hydra 2 and SOLiX, DT Swiss 240 and 180, Hope Pro 5 and Chris King MTB hubs, usually with Sapim CX-Ray, Laser or D-Light spokes or DT Aerolite and Competition, and brass or alloy nipples.
Tire range on the Whisp is 2.2 to 2.4in, tubeless-ready tires only on the hookless bead. The configurator recommends spoke count and lacing from your bike type and weight.
Build a wheel around it
Offered for gravel and road disc, mountain bike and MTB single-speed builds in our Custom Wheel Program. Start with the Convergence We Are 1 Whisp Carbon Rim and the configurator pins it for you, then checks each choice you make against it.
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.
How Convergence We Are 1 tests its rims
We Are One Composites hand-lays its carbon rims in Kamloops, British Columbia, and states all of its manufacturing happens under one roof there: it designs and CNC-machines its own aluminum molds, develops its own layups, and each rim is hand laid and hand signed by the person who laid it up. We Are One states it has tested its products and knows they exceed industry standards, and that its in-house fatigue and strength testing meets current test standards, but it publishes no impact energies, fatigue-cycle counts or ISO/EN/UCI results. A February 2024 Radavist factory visit described in-house oven curing, hand-marked drilling and a quality-control check of every rim before lacing. For the Convergence rims, CompositesWorld reported in November 2022 that We Are One's in-house testing found Convergence 32% stronger than its Union 29 in rim, credited to Boston Materials ZRT film with Z-axis carbon fiber reinforcing the spoke bed; the Whisp is 21 mm high with a 29 mm internal width.
Since Industry Nine acquired We Are One in June 2025, rim warranty claims go through industrynine.com. We Are One's statement is: "If you break a rim while riding, we will send you a new one. Period." with no cost except shipping. Industry Nine's warranty page states carbon rims are covered for life against defects and for impact damage while riding within the wheel's intended use, for the original purchaser. A July 2025 Radavist review describes 50% crash replacement for second owners or non-riding damage. No rider weight limit or maximum tire pressure is published on the brand's pages.

Building it at ProWheelBuilder
We Are One makes the Convergence Whisp; ProWheelBuilder is an independent wheel builder in Georgia, not the manufacturer. Spokes are cut from the ERD we measure on the actual rim, the wheel comes up in stages on a tensiometer, and it is stress-relieved and trued before it goes in the box; tape and a valve go on if you ask.
The configurator filters to what fits, crosses out what is not made, and prices the build as you go.
Warranty
Manufacturer's warranty. Convergence We Are 1 warrants this product against defects in materials and workmanship. The duration, conditions and claim process are set by Convergence We Are 1 and can change without notice, so ask us and we will confirm the current terms before you buy.
ProWheelBuilder. Wheels we build around this part are covered by our own one-year warranty alongside the maker's. Within the year: broken spokes replaced regardless of cause, and the labor on the wheel - truing, re-tensioning or a complete rebuild - included. A manufacturer-covered rim or hub failure is a claim we make and manage for you; one they will not cover is answered with an eligible replacement at 25% off retail. Shipping each way is yours. Parts you supply yourself fall outside it.

Whisp Carbon Rim questions
What tire width suits this rim?
At 29mm inside this is a trail width, sized around 2.1 to 2.4in tires. That is wide enough to stop a modern trail casing rolling under you in a corner without pushing the tread so flat that it wears down the middle.
Which spokes and nipples suit the Convergence Whisp?
For most riders a double-butted spoke such as Sapim Race or DT Competition with brass nipples; lighter riders can go to Sapim Laser or CX-Ray. The configurator recommends a gauge and count for the Convergence Whisp from your bike type and weight.
Sector, Triad or Fuse?
Sector at 29mm for trail on 2.3 to 2.4in tires; Triad at 30mm for enduro and aggressive trail on 2.4 to 2.6in; Fuse at 33mm for e-bikes and the hardest riding.
What is Convergence?
We Are One's second-generation rim profile: a shallow section with alternating curves in the wall that buttress the spoke angles, and ZRT films in the layup, 32% stronger than the Union rims with the same compliance.
Is the Triad hookless?
Yes. Use tubeless-ready tires and stay under the maximum pressure printed on the rim.
Is We Are One made in Canada?
Yes. Every rim is laid up and molded by hand in Kamloops, British Columbia, with a lifetime warranty.
Is ProWheelBuilder the manufacturer of the Convergence We Are 1 Whisp Carbon Rim?
We are not. Convergence We Are 1 manufactures the rim; ProWheelBuilder's part is the wheel: measuring, lacing, tensioning and truing it here in Georgia.
