Strap for 29er Black / Bracelet

The M1-25-23-MB features a lug width of exactly 18mm, an uncommon dimension that requires specifically sized straps. Unlike the industry-standard 20mm or 22mm, this measurement is a precise constructive characteristic of this model. To verify: use a digital calliper, positioned perpendicularly between the two lug pins, measuring from centre to centre.

Selection depends on intended use and aesthetic preference. For formal contexts, alligator or vegetable-tanned calf leather delivers refined proportions without visual excess. Shell Cordovan develops distinctive patina over time. For casual interpretation, a grey-dark canvas or cotton NATO amplifies technical sporting character. In rubber, the 29er assumes pure instrument personality—ideal for daily wear without aesthetic compromise.

The process is straightforward: employ a spring bar tool to apply controlled pressure on one of the elastic pins securing the strap. Press towards the case centre until the pin retracts, then extract the strap outward. Repeat on the opposite side. Insert the new 18mm strap, aligning the holes and ensuring both pins snap securely into position. Always verify the strap is centred and stable before wearing.

Certainly. milanostraps.it offers a dedicated collection of 18mm straps, handcrafted in Italian leather, NATO, and technical rubber. Each model undergoes mechanical compatibility and quality construction verification. Atelier Casati Milano, by appointment, provides bespoke consultation for selecting the colour and material combination most coherent with your style and intended use.

Duration depends on usage intensity, climate, and tanning quality. A high-quality vegetable-tanned leather strap—such as those from milanostraps.it—withstands 3–5 years of daily wear under normal conditions. Water and humidity exposure reduces longevity; timely drying extends it. The patina developing over time is a desirable characteristic, not a defect. For extreme-condition exposure, a technical rubber strap offers superior durability: 7–10 years with appropriate maintenance.
