Stans No Tubes Neo Axle End Caps

Stan's NoTubes Neo Axle End Caps (PN 090852, MPN ZH0771) are engineered as exact replacement and conversion end caps for Stan's Neo hub family. Designed to maintain bearing preload and hub spacing, these caps let you switch axle standards quickly—front 100/110mm spacing with QR, 12mm, 15mm or 20mm thru-axle options are available depending on the variant.

Manufactured from CNC-machined aluminum with an anodized finish, the end caps are built to resist corrosion and wear while keeping weight low (shipping weight ~0.05 lb). The mating surfaces are machined to tight tolerances so seals and bearings retain correct alignment, reducing play and protecting internal bearings from grit and moisture.

Robust construction and precise tolerances: Each cap is CNC-machined from high-strength aluminum alloy for stiffness and low weight. The anodized surface improves durability and reduces the chance of galling on repeated installs.

Real-world benefits: Better bearing life through correct preload, simple conversion between axle types without replacing the hub body, and minimal added weight. Common practical advantages are faster wheel swaps, fewer spares to carry, and consistent wheel dish and brake alignment.

• CNC-machined aluminum body for strength and light weight
• Multiple axle standard variants: QR, 12mm, 15mm, 20mm
• Available for 100mm and 110mm front spacing
• Precision mating surfaces to preserve bearing preload and seal interface

These end caps are specifically sized for Stan's Neo front hubs—confirm hub model and desired axle standard before ordering. Variants include Front 100mm (QR, 12mm TA, 15mm TA, and 12mm CL) and Front 110mm (20mm TA). The 12mm CL option indicates a centerlock rotor-compatible cap while keeping hub spacing at 100mm.

Installation is typically a press-fit or slip-fit onto the hub's bearing journal and can be swapped using basic tools or a soft mallet where applicable; always check that bearings are seated and that axle spacing matches your fork's spec. If your fork requires a specific thru-axle length or shoulder, verify length and thread engagement to ensure proper axle clamping and rotor alignment.

These end caps are for mountain bikers, mechanics, and workshop techs who own Stan's Neo hubs and need spares or want to convert axle standards. They're ideal for riders who switch between bikes or forks (trail to cross-country forks) and need fast, reliable conversions without changing the hub body.

Also useful as a maintenance spare — keeping a set of end caps in your toolkit reduces downtime after travel, crashes, or when upgrading wheelsets. If you demand precise bearing alignment, lower maintenance, and a lightweight solution for axle conversions, these end caps are a practical choice.

When buying replacement or conversion end caps for a hub, start by confirming your hub family (Stan's Neo), front hub spacing (100mm or 110mm) and the axle diameter your fork requires (QR, 12mm, 15mm or 20mm). Choosing a cap that matches both the hub's bearing journal and your fork's axle ensures correct preload, rotor alignment, and safe clamping.

Also consider materials and serviceability: aluminum end caps are light and stiff, but inspect seals and bearing seats during installation. If you frequently swap forks or wheelsets between bikes, keep spare end caps in your workshop or travel kit to avoid delays and maintain optimal wheel performance.
