Picture the worst version of race morning. You’re in the start pen, number pinned, legs warm. A commissaire walks the line with a clipboard, checking equipment against the UCI list. And you have no idea whether the wheels you spent months saving for are on it.
That uncertainty is the problem we set out to remove. As of 8 June 2026, every wheelset in the Yoeleo NxT SL2 road range, the C45 NxT Gravel, and both QianKun CS carbon-spoke models has been formally homologated by the UCI and added to the official list of approved wheels. You can line up, hand your bike to a commissaire, and race with a calm head.

THE QUICK VERSION
UCI homologation isn’t a performance claim or a quality badge — it’s a legality check. It confirms a wheel meets the construction and safety criteria in the UCI technical regulation, so it’s cleared for UCI-sanctioned road and gravel competition.
We’ve now completed that process across the NxT SL2 and QianKun lines, and the certificates are dated and signed.

This post explains what the approval covers, why it matters more in 2026 than it used to, and exactly which wheels are on the list.
What does “UCI-approved” actually mean for a wheelset?
UCI approval confirms a wheel’s construction meets the UCI’s technical criteria for competition — it’s a legality clearance for racing, not a measure of how fast or how durable the wheel is.
Here’s the distinction that trips people up. The UCI splits wheels into two groups. A “traditional” wheel — a shallow rim with a full count of metallic spokes — is legal by default and needs no paperwork. Anything outside that definition, which includes essentially every modern deep-section carbon aero wheel, is classed as a non-standard wheel and has to be individually submitted, tested against the criteria in Article 1.3.018 of the UCI regulations, and added to a published list before it can be raced.
In plain terms: a deep carbon wheelset is not race-legal just because it’s well made. It’s race-legal once it’s on the list. The two are separate, and only one of them is something a commissaire can check at the start line.
That’s the whole reason this work matters. The engineering was never in question — the homologation is what turns engineering into a wheel you’re allowed to race.
Why we updated the list now
The UCI tightened its technical regulation effective 1 January 2026, with non-standard wheels expected to demonstrate compliance with current impact and dimensional standards (referenced through ISO 4210-2:2023) to stay on the approved list.
When the governing body raises the bar, two things can happen to a wheel brand. It can stay quiet and hope its older approvals carry over, or it can re-file and make sure every current model is documented against the current rules. We chose the second. Rather than leave any ambiguity for a rider at registration, we ran the full homologation across the NxT SL2 and QianKun families so the approved list reflects exactly what we sell today.
This is also just consistent with how we already build wheels. Both the NxT SL2 and QianKun lines are validated to an internal rim-impact standard of 120 joules — three times the UCI’s 40-joule minimum — alongside 600 KGF spoke tension and a hub torque protocol of 230 Nm across 52,000 cycles. The homologation paperwork and the test bench are pointing in the same direction: a wheel that’s legal to race and engineered well past the floor.
We’ve been submitting wheels for UCI approval for a long time. The June 2026 filing isn’t a new direction — it’s us keeping the list current as the rules moved.
Which Yoeleo and QianKun wheels are UCI-approved?
All seven 2026 wheelsets below are homologated under Article 1.3.018 with an approval date of 8 June 2026. Every model is a disc-brake, clincher/tubeless wheelset.

All certificates issued by the UCI Equipment Unit, Aigle — dated 8 June 2026.
A few things worth pointing out from the certificates themselves. The QianKun CS models carry their own approval — the proprietary 2:1 front lacing (21 carbon spokes up front, 24 in the rear) was submitted and homologated as built, not adapted to fit the rules. And the C45 NxT Gravel approval means you’re covered for UCI-sanctioned gravel, a discipline where equipment scrutiny has grown quickly.
Whether you’re racing the deep C88 against the clock or chasing a KOM on the CS50, the wheel under you is on the list.
What the certificate does — and doesn’t — guarantee
A UCI certificate confirms the model is legal for UCI competition; it doesn’t transfer responsibility for product quality or safety away from the manufacturer, and that’s exactly where we want it.
The UCI is explicit about this in the certificate: approval is based on the documentation submitted, and the manufacturer remains responsible for ensuring the product meets prevailing safety and quality standards. We read that as a feature, not fine print. The governing body confirms the wheel is race-legal; standing behind how it’s built, how it holds up, and how it performs is on us — backed by our internal testing and a 3-year warranty across all NxT SL2 and QianKun components, including hubs.
That’s the honest division of labor. Homologation gets you to the start line. Engineering gets you to the finish.
Frequently Asked Questions
Are all Yoeleo wheels UCI-approved?
The full 2026 NxT SL2 road range (C35, C50, C60, C88), the C45 NxT Gravel, and both QianKun CS carbon-spoke wheelsets (CS50, CS60) are homologated under UCI Article 1.3.018, with certificates dated 8 June 2026. Each is a disc-brake clincher/tubeless wheelset.
Does UCI approval mean the wheels are faster or stronger?
No. UCI approval is a legality clearance confirming a wheel meets the construction criteria for competition — it says nothing about speed or durability. Those come from design and testing. Our wheels are separately validated to a 120 J rim-impact standard, three times the UCI’s 40 J minimum.
What is a non-standard wheel under Article 1.3.018?
A non-standard wheel is any wheel that falls outside the UCI’s “traditional” definition — most commonly deep-section carbon aero wheels. These must be individually submitted, assessed against Article 1.3.018, and added to the UCI’s published list before they’re legal to race.
Can I race these wheels in gravel events?
Yes. The SAT C45 DB Pro NxT Gravel is homologated under the same Article 1.3.018 process, so it’s cleared for UCI-sanctioned gravel competition alongside the road models.
Do I need to carry the certificate to a race?
Generally no — commissaires check equipment against the UCI’s official approved-wheels list rather than asking riders for paperwork. Because every model above is on that list, you’re covered at registration without doing anything extra.
