A10

The Purist -   A simple, timeless titanium pure road bike. Our aim was to build a titanium bike that was race ready and close to the UCI weight limit of 6.8kg without using an abundance of weight weenie components. To save weight we left some cables exposed and we optimized tubing dimensions to bring the weight down far enough that a sub-seven kilogram bike is achievable with the right component choice.

Just like our A30 Captain the geometry is nimble enough to give you that race bike feeling and stable enough to encourage you to seek out switchback after switchback.

Design Details

Fast and stable road bike 

Our A10 was designed with stability and speed in mind. Our backyard and testing grounds are the mountains which surround Beijing. Every week we are are out pushing our bikes to the limit on the smooth descents in the area. The geometry of the bike was designed to be fast and stable to really take advantage of the type of riding in the region. The stack values on our frames are modest allowing you to get nice and low (reducing your centre of gravity and increasing the stability of the bike at speed) or add in some spacers to achieve a more upright position with extra comfort.

T47 Bottom Bracket

We’ve adopted T47 across the Serk Titanium line. The standard is here to stay and allows you to fit almost all the standard sized cranks on the market creak free. T47 is threaded which virtually eliminates bottom bracket creaking. It also allows for much easier service and installation.

Semi Integrated Cabling

We love the clean aesthetic of internal cabling. However we also like lightweight bikes. Instead of using a fully internal cable routing system with a heavier cast bottom bracket we opted for semi-integrated. Cables are hidden from the inlet ports near the head tube before exiting under the bottom bracket where they are exposed but hidden under the bike. This configuration is the lightest design option while still retaining a clean aesthetic - the perfect balance between performance and beauty. The included cable ports can be swapped out for Di2 versions if you prefer an electronic groupset from Shimano. Prefer no ports for an wireless SRAM build? Message us and we can produce a customised version of the frame.

Bike for life

Before we started our own bike brand we ran a bike shop for almost a decade. You learn a lot on the shop floor servicing and repairing bikes for all brands and all walks of life. Nothing irks us more than the tendency for some brands in the industry to develop proprietary parts with unique sizing and new gimmicks. After a few years it can be hard to source replacements and after a decade or so you can completely forget it. Sometimes something as simple as a worn out headset bearing of a weird size or an odd shaped aero seatpost can render an older bike completely obsolete. What a waste in so many ways.

Our bikes are designed for life. We chose titanium as a material for its longevity and we carefully consider the specs on our bikes with the same philosophy. Everything on our bike is standard size and commonly available. In a decade if you need a new headset, seatpost or bottom bracket for your Serk bike it will be easy to source. Even our forks have a number of different aftermarket options available with the same configuration making them easy to come by wherever you are exploring new frontiers.

This approach to bike design is not only smart but its also responsible. We've designed a timeless bike that will last and give back for decades to come. That's how it should be.

Our Frontier Cycling pattern is detailed on the stem cap as a subtle reminder of the geometric patterns of central asia.

We spend a lot of time curating the specs of each bike to balance performance and maintain a minimal aesthetic.
