Size
Fork

The Randbezirk 4100 has come a long way and it is finally here! In my eyes it is the perfect steel fixed gear that can handle anything you throw at it. Tracklocross? Not an issue. Trackpacking? Absolutely. Commuting or daily riding in any weather? Yes please. Alleycats on any terrain? Where's my spoke card?

Made from double-butted 4130 tubing and paired with a modern geometry, the frame will provide the perfect combination of compliance and responsiveness. Clearing 45c front and rear it will feel right at home, no matter where you currently are.

 

Pre-Order!

Please be aware, that this is a pre-order. A second payment of 350€ will be due upon completion of the frames. More Info in the FAQ.

Geometry Chart
Size & Fit

The Randbezirk 4100 is designed around a 120mm stem, so keep this in mind when choosing your size. I am 172 and ride a size S with the bike set up as pictured. Due to the high bottom bracket and potentially wide tires, standover will be higher than usual.

Frequently asked questions
How does the Pre-Order work?

The Pre-Order is split in two phases. First is the pre-order for 400€ which will be open until 6.12.2025. Once it closes and the frames are ready to be shipped, a second fulfillment payment of 350€ will be due. Detailed instructions will be sent via e-mail.

Current lead time is around 3 months so expect the frames to be ready in Febuary / March of 2026.
