Senior-Led Coordination
Your project is coordinated by senior decision-makers, with engineering, production, QC, and shipment teams aligned from first inquiry to final release.
Factory-Built
In-house manufacturing. End-to-end control. 3-level QC through Product Testing, In-Process Self-Checking, and QC Inspection.
Performance Driven
Structural validation before any mold is cut. W1-W4 weight versions and layup choices are matched to your programme requirements.
Global Partner
Nine years with a Polish brand we've never met in person. They grew to 500 wheels a month. We grew with them.
In-house steps
Reliability begins before a rim reaches finishing. Material selection, cutting, layup, molding, drilling, surface inspection, and dimensional checks are tracked through one production workflow, so the approved sample can remain the reference for later batches. Paint and finishing are coordinated with our long-term partner.
3-level QC system — from testing to final release
Production chain
Paint partner
Finish consistency is managed against the approved artwork, color, and surface reference. Keeping those references with the production record reduces handoff errors when a program moves from sample approval to repeat orders.
Production process
Design validation
DeerCycles uses a three-level QC system: Product Testing, In-Process Self-Checking, and QC Inspection. Every rim receives a 150 psi factory inflation check before finish or shipment review; this is a QC check for bead seating, pressure holding, visible cracks, and tire-rim fit, not a recommended riding pressure for every rim and tire combination.
01
Dimensional / Runout Review
Roundness, flatness, ERD consistency, and runout are checked with measurement tools on every rim during QC inspection.
02
Raw-Rim Inflation Check
Every rim receives a 150 psi factory inflation check for bead seating, pressure holding, visible cracks, and tire-rim fit. This is not a riding-pressure recommendation.
03
Post-Inflation Width Review
Rim outer-width measurement after inflation. DeerCycles can compare rim width before and after factory validation to review visible deformation, tire security, and overall rim integrity according to the approved project method.
04
Rim Lateral Stiffness Review
Lateral behavior can be reviewed against the approved rim or wheel-build specification.
05
Spoke-Hole Tensile Review
Spoke-hole strength validation can be performed up to 350 kgf, according to the approved project method.
06
Rim Vertical Stiffness Review
Rim vertical stiffness can be reviewed according to the approved project method and the rim or wheel-build specification.
Test Records
Original test reports, images, and videos retained for every batch. Available to OEM partners on request.
Testing & validation support
DeerCycles supports OEM and ODM rim and wheel programs with a documented testing and validation path. Validation is defined per project and matched to the brand's riding category, tire system, pressure range, spoke count, and target market — not sold as a one-size certificate.
01
Project-specific validation path
Validation targets are set per program — riding category, tire system, pressure range, spoke count, target rider and system weight, and destination market — so the test plan reflects how the wheel will actually be used.
02
QC records for OEM programs
Batch QC records can cover dimensional inspection, drilling accuracy, roundness and flatness, spoke-bed review, the 150 psi raw-rim inflation check, finish, decal and laser sign-off, and final inspection before release.
03
Testing photos and videos
Testing photos and videos can be provided during sample approval, or for a brand's UCI application preparation where required. Original test reports, images, and videos are retained per batch and available to OEM partners on request.
04
Impact / fatigue / spoke-bed validation support
Where required by the approved project method, validation can include spoke-hole strength up to 350 kgf and, for newly developed wheelset programs, complete wheel fatigue validation up to 800,000 cycles (exceeding the commonly referenced 750,000-cycle ISO fatigue baseline). These are current DeerCycles QC and project-validation references applied per program, not blanket product certifications.
05
Third-party test coordination
If a customer's market, distributor, or race program requires external testing, DeerCycles can discuss the required standard, scope, and documentation path before production. EN/ISO-related testing requirements can be reviewed for the project; the specific scope is agreed per program.
06
UCI application documentation support
For race-focused OEM programs, DeerCycles can support brand customers during the UCI approval preparation stage with documentation for the customer's own UCI application.
UCI application support
For race-focused OEM wheel or rim programs, DeerCycles can support brand customers during the UCI approval preparation stage. We can provide product specifications, rim drawings, QC records, testing photos, and testing videos where required, so the brand can submit the correct documentation for its own UCI application. Final approval depends on UCI review and the customer's submitted product program.

Toray prepreg options include T700, T800, and T1000. Fiber orientation, layup schedule, and weight-version direction are reviewed per mold and project target, helping keep weight and stiffness consistent batch to batch.
W1, W2, W3, and W4 are selected around the project: riding use, rim profile, target weight range, stiffness target, tire system, drilling plan, and QC method. DeerCycles reviews these inputs before sample approval so the rim direction is clear before production planning.
Customization
Carbon rim families
Most OEM carbon rim programmes start from a known platform: road, gravel, MTB, 32ER, small wheel, or a one-piece carbon spoke wheelset platform. Each family can be adjusted by depth, inner width, hole count, drilling angle, finish, decal and W1-W4 weight-version direction.
If the right product family is still unclear, use the OEM rim and wheelset fit finder before sending a broad RFQ.
For brands that need a signature profile, DeerCycles can move from reference geometry to ODM engineering, testing, mold development and production under one project team.
Capacity & lead time
Repeat-order reliability comes from carrying the approved rim specification, finish reference, QC checkpoints, and packing details into each batch. As a program grows, those records give the buyer and production team the same release standard.
Every rim comes with a 3-year warranty and a crash-replacement programme.
