Convergence We Are 1 Fuse Carbon Rim
The We Are One Convergence Fuse is the widest and strongest rim in the Convergence range, laid up and molded by hand in Kamloops, British Columbia: 33mm inside for 2.5 to 2.8in tires, the shallow Convergence section with its alternating wall curves and ZRT composite films in a layup for e-bikes, bike park and riders who break everything. It comes in 29in with 28 or 32 hole and carries the lifetime warranty.
This page covers the Convergence We Are 1 Fuse Carbon Rim in 29in, 27.5in. The Fuse 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 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 Fuse wheel is built for the loads an e-MTB or a park bike puts through a rim, and it still rides like the rest of the range: damped, grippy and precise rather than harsh. The 33mm bed keeps a 2.6in tire square at low pressure and the layup takes the hits. For trail and enduro the Triad is lighter; for e-bikes, park and the hardest riding, the Fuse is the We Are One rim we recommend.

This listing
This is the 29in, 27.5in listing of the Convergence Fuse, 32h, about 579g, 33mm inside, 18.5mm deep, disc. Pick the size that matches your frame; the profile and construction are the same across the range.
This is the disc-brake Convergence Fuse: 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 Fuse Carbon Rim comes in 29in, 27.5in and 32h drilling. It is a disc-brake rim. We build the Fuse on Industry Nine Hydra 2, DT Swiss 350, Hope Pro 5, Onyx Classic and Chris King MTB hubs in Boost spacing, usually with Sapim Strong, CX-Sprint or Race spokes or DT Alpine III and Competition, and brass nipples.
Tire range on the Fuse is 2.5 to 2.8in, tubeless-ready tires only on the hookless bead. Pick e-bike or downhill as your bike type in the configurator and it recommends a spoke count and lacing pattern.
Build it with us
We build this rim to order. Open the Custom Wheel Program with the Convergence We Are 1 Fuse Carbon Rim already selected and pick the parts around it; it is offered for mountain bike, MTB single-speed and fat 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.
What Convergence We Are 1 says about testing
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 Triad is 18.5 mm high with a 33 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 Fuse; ProWheelBuilder is an independent wheel builder in Georgia, not the manufacturer. Every Convergence Fuse wheel we build gets spokes cut from the rim's measured ERD, is tensioned in stages with a gauge, stress-relieved and trued before it ships. Tubeless tape and a valve are fitted on request.
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
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. Lace this into a wheel here and the finished wheel gets our own one-year warranty as well as the maker's. For twelve months we replace broken spokes however they broke, and the work on the wheel is on us - truing, re-tensioning, a rebuild where it is needed. If the rim or hub is covered by its manufacturer we put the claim in and chase it; if it is not, we supply an eligible replacement rim or hub at 25% off the current retail price. Carriage both ways is the customer's, and this does not cover wheels built from parts you send in.
Full terms are on our Policies & Warranty page.
Fuse Carbon Rim questions
What tire width suits this rim?
33mm inside is an enduro width, meant for 2.3 to 2.6in tires. It gives a big casing a square, supported profile so you can drop pressure for grip without the tire folding, which is the whole point of a rim this wide.
Which spokes and nipples suit the Convergence Fuse?
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 Fuse from your bike type and weight.
Sector, Triad or Fuse?
Sector at 28mm 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 it tubeless-ready?
Yes. Convergence We Are 1 lists the Fuse Carbon Rim as clincher tubeless compatible; we tape and fit a valve when you choose the tubeless option.
