Ordering Information
Frames are built to order in small production batches. For this first release, we’re offering the Bergsra in Medium & Large sizes only. Small and XL will follow in future drops.
Each frame is made for a specific rider — not pre-built, not pulled from a shelf.
To secure your slot, a 50% deposit is required at the time of ordering.
Following the post-deposit consultation to confirm your final spec and pricing, the deposit becomes non-refundable, as materials, components and production time are allocated specifically to your build.
The remaining balance will be due when your frame is completed and ready for shipping.
Estimated lead time: 6–10 weeks from order confirmation.
Build Log
During the build process, you'll be invited to join a private workshop update channel (via Telegram or WhatsApp). You’ll get photos, video walk-throughs, and updates directly from the workshop — following your frame through each stage of the process. You'll also have the option to ask questions directly, without the noise of a public group chat.
Shipping
Final shipping costs will be calculated before dispatch based on your destination.
We'll contact you ahead of final payment with an up to date shipping price. If you'd like an estimated quote in advance, just get in touch, or see our shipping page here.
This is not mass production.
Each frame is hand-built with care, and numbers are strictly limited per batch. Once a batch is sold out, the next slots will open when the previous batch is nearing completion.
