Why We Chose Tenax® Fasteners For Our Cycling and Brompton Bags

At Souma Leather, we design bike bags that combine craftsmanship with function — whether you're riding a folding Brompton through the city or taking your vintage steel bike on a weekend tour.

That’s why we use Tenax® fasteners across both our Brompton bags and saddle bags for classic bikes. They're not just stylish — they’re secure, reliable, and made for riders who notice the details.

What Are Tenax Fasteners?

Tenax® fasteners are high-quality, quick-release snap-locks originally developed in Germany. They’re often used in classic cars and boats to secure panels and covers — meaning they’re made to hold tight in motion, under vibration, and in changing weather.

Each fastener consists of a solid stud and a locking socket. Once pressed together, they stay locked — until you intentionally lift the center pin to release them.

Why We Chose Tenax for our Cycling Accessories and Brompton Bags

Whether your bag sits on a Brompton front carrier or hangs beneath your saddle on a vintage bike, Tenax® fasteners offer key advantages:

1. Secure Under Vibration

Whether you’re riding cobblestones or folding your bike on a train platform, the fastener stays closed.

2. One-Handed Release

The fastener opens by lifting the center pin — easy to use with one hand, even with gloves.

3. Elegant and Minimal

No bulky buckles or Velcro here. The Tenax® fastener has a clean, industrial look that pairs beautifully with leather.

4. Long-Lasting

Tenax® fasteners are made from marine-grade stainless steel or nickel-plated brass. They outlast other snaps, and they won’t degrade over time.

Designed for Cyclists Who Expect More

You don’t ride a Brompton because it’s ordinary — you ride it because it’s clever, compact, and well-designed. Our bags are the same. The Tenax® closure fits that philosophy: mechanically smart and satisfying to use.
