Testing & validation support · For OEM rim and wheel programs
Carbon rim testing and validation support is how DeerCycles helps OEM and ODM brands confirm a rim or wheel program before production. Validation is defined per project and matched to riding category, tire system, pressure range, spoke count, and target market — not sold as a one-size certificate. This page summarizes the QC system, the checks that may apply, the records you can request, and the documentation support DeerCycles can provide for a brand's own UCI application. The testing framework below shows the full set of checks a program can draw from.
How we validate
Validation is defined per project — matched to riding category, tire system, pressure range, spoke count, target rider and system weight, and destination market. The scope is agreed during sample approval, supported by a three-level QC system: Product Testing, In-Process Self-Checking, and QC Inspection. In-process checks include post-molding surface review and drilling-quality review; QC inspection covers rim weight, roundness, flatness, hole count and diameter, surface, decal, tubeless setup, and packing before release. Rim weight is recorded per unit and held within ±15g of the program target; any unit over target is flagged to the customer before shipment.
The framework below shows the checks DeerCycles can apply. Not every check applies to every project, and sample condition and acceptance criteria are confirmed by project.
Media
Testing photos and videos can be provided during sample approval, or for a brand's UCI application preparation where required.

Framework
Twenty-two validation and documentation modules, grouped the way OEM buyers plan a program. Modules marked “records on request” run as text-described checks today; photos and videos are added as programs allow.
Geometry consistency is the first thing a buyer's wheel builder notices.
Rims must build into true wheels without fighting the rim. During dimensional QC — before sample approval and on repeat production — trueness, runout, roundness, and flatness are reviewed with digital indicators against the sample plan; roundness and flatness are held under 0.2mm on a 100% fixture check. Dimensional QC records per batch are available to approved OEM partners.
Photo in gallery aboveConfirms ERD, inner and outer width, depth, drilling positions, and hole diameter against the approved drawing; ERD is held within ±0.2mm. Used at sample stage and per batch; scope agreed during sample approval. Batch dimensional records on request.
Records on requestReviews whether the rim shows permanent deformation after load or inflation checks, according to the approved project method. Results are recorded per sample plan — a project-specific check, not a blanket guarantee.
Records on requestTubeless and high-pressure fit problems should be found in the factory, not in the field.
Confirms bead seating, tire security, pressure holding, and visible deformation for clincher and tubeless programs; raw-rim checks can include a 150 psi factory check. This is a QC validation check, not a riding-pressure recommendation. Final pressure, tire type, and acceptance criteria are confirmed according to the approved project method.
Photo in gallery aboveCompares rim outer width before and after factory inflation to review visible deformation and overall rim integrity; inflation-related deformation has been confirmed stable under 0.3mm. Measured per the approved project method; records on request.
Photo in gallery aboveReviews rim and tire-system behavior after elevated-temperature exposure, where the project's market or use case requires it. Scope agreed during sample approval.
Records on requestRim-level structural checks, defined per program — not sold as a one-size certificate.
Rim-level review of structural response under lateral load, according to the approved project method. Sample condition and acceptance criteria are confirmed by project.
Photo in gallery aboveRim-level review of structural response under vertical load, according to the approved project method. Sample condition and acceptance criteria are confirmed by project.
Photo in gallery aboveValidation can be performed up to 350 kgf according to the approved project method. Two spoke-bed constructions are offered — CNC-drilled (standard) and molded-in spoke holes that keep the fiber continuous through the bed — with the construction type confirmed during sample approval. Sample method, force level, and acceptance criteria are confirmed by project.
Photo in gallery aboveImpact or concentrated-load review for programs whose riding category requires it — MTB, gravel, or race programs. Method and energy level are confirmed by project; records can be prepared for approved OEM programs.
Records on requestSome questions can only be answered on a built wheel.
A trial build confirms spoke tension behavior, nipple seat fit, and trueness stability before a program commits to volume. Used at sample approval for new wheelset programs; records on request.
Records on requestComplete wheel fatigue validation can be performed up to 800,000 cycles for newly developed complete wheelset programs, according to the approved project method. The commonly referenced ISO fatigue baseline is 750,000 cycles.
Records on requestReviews the wheelset as a system: rim, spokes, nipples, hub interface, and tension balance against the approved specification. Scope agreed during sample approval.
Records on requestValidation means little without material and process control behind it.
Incoming carbon prepreg is cold-stored and reviewed per batch against storage and handling requirements; resin content is verified by DSC (differential scanning calorimetry) before release to layup. Records on request.
Records on requestIn-process review of layup execution against the approved layup plan for the program's weight tier. Records on request.
Records on requestPost-drilling review of spoke-hole quality, spoke-bed thickness, and nipple seat condition; CNC drilling uses diamond-tipped bits replaced every 30–40 rims to hold hole quality, and drilling-quality review runs on a recurring in-process schedule. Records on request.
Records on requestSurface, decal, and finish sign-off per outgoing shipment, including paint-factory surface sign-off and senior-management pre-shipment review.

Test records
Original test reports are retained per batch and available to OEM partners on request. A sample test-record format can be shared during sample approval.
Scope
Everything on this page is validation support defined per project — not blanket product certification. Not every check applies to every product or order; the scope depends on project requirements and is agreed during sample approval. EN/ISO-related requirements can be reviewed for the project, but this page does not imply blanket ISO certification or pass/fail status. UCI approval always belongs to the customer's own application.
By project type
| Project type | Typical validation focus (per approved method) | Records |
|---|---|---|
| Road / all-road | dimensional, inflation, complete wheel fatigue, finish | on request |
| Gravel | inflation, tubeless fit, dimensional, complete wheel fatigue | on request |
| MTB / 32ER | strength / impact emphasis, spoke-bed, dimensional | on request |
| Race-focused | project-specific validation + UCI documentation support | records + UCI doc support |
Before you ask
Send the riding category, tire system and pressure range, target inner width and depth, spoke count and drilling, target weight, destination market, and any testing or UCI requirements. The clearer the target, the more precisely the validation scope can be set.
FAQ
Validation is defined per project and matched to riding category, tire system, pressure range, spoke count, and target market. Depending on the approved project method, it can include dimensional and roundness/flatness review, raw-rim inflation checks, spoke-hole strength, and complete wheel fatigue validation. These are current DeerCycles QC and project-validation references, not blanket product certifications.
Original test reports are retained per batch and available to OEM partners on request. Testing photos and videos can be provided during sample approval, or for a brand's UCI application preparation where required.
DeerCycles supports the UCI approval preparation stage for the customer's own application. For race-focused OEM rim or wheel programs, we can provide specifications, rim drawings, QC records, and testing photos or videos where required, so the brand can submit documentation for its own application. Final approval depends on UCI review.
Validation is defined per project and matched to riding category, tire system, pressure range, spoke count, and target market; the scope is agreed during sample approval.
No. The framework shows what DeerCycles can apply. Each program selects its validation scope at sample approval, based on riding category, market, and project requirements. Recurring production QC checks apply per batch; project-specific validation applies as agreed.
Complete wheel fatigue validation can be performed up to 800,000 cycles for newly developed complete wheelset programs, according to the approved project method. The commonly referenced ISO fatigue baseline is 750,000 cycles. Fatigue validation is performed on complete wheels, not described as a rim-only check.
