Serk Titanium Cycles

Julien set out from Tokyo with France on the horizon, a 12,000 km solo ride across Asia and into Europe. He is more than 9000km in, carrying everything he needs on a Serk A21 and collecting the sort of moments many cyclists dream of collecting themselves.

Back in February, Julien got in touch looking for one bike for a very particular job. He wanted to travel fast and light through Japan, Korea, China and Europe, but still have the confidence to take on the rough, remote roads waiting further west in Central Asia.

The A21 was the clear choice.

Its titanium frame gives him the blend needed for a journey like this. Light enough to keep moving quickly on long tarmac days. Comfortable enough for consecutive weeks in the saddle. Strong enough for loaded riding, rough roads, unexpected crashes, and the occasional ride in the back of a truck.

Julien’s setup is deliberately simple and proven:

• Serk A21 titanium frameset
• Shimano GRX mechanical groupset
• DT Swiss G1800 wheelset
• 34 mm tyres for fast, comfortable road riding
• Full bikepacking kit for life on the road

As the route became rougher through Central Asia, Julien moved to 42 mm tyres for more grip, control and comfort on broken roads.
So far, he has crossed Japan, Korea, China, Kazakhstan, Kyrgyzstan, Tajikistan and Uzbekistan. He even stopped by the Serk office in Beijing along the way. Now, he has reached Georgia.

From Japanese city streets to the high passes of Kyrgyzstan and Tajikistan, the conditions have changed constantly. Smooth tarmac one week. Rough dirt, big climbs and long empty distances the next.

That is exactly what the A21 is built for. Fast and efficient when the road is smooth. Capable and dependable when the route becomes more remote, rough and unpredictable.

France is still some way ahead. Good luck Julien on this inspiring adventure! Follow along Julien P.

We’re thrilled to partner with to create a special edition of our new A40, debuting at in London this weekend.

This build is our lightest yet, tipping the scales at just over 6.7 kg including bottle cages. The A40’s newly developed hydro-formed tubeset incorporates refined, weight-saving details, dropping 100 grams from the A30 frame. Paired with EXS’s top-tier lightweight carbon components, the result is a truly remarkable 6.7 kg—an impressive figure for a titanium bike.

Also making its debut is our new Luminal finish, crafted with Volatee ceramic paint. The design expresses the concept of liminality—the transition between the known and the unknown, the crossing point between territories. It reflects the spirit of exploration that defines us, where each ride invites you to step beyond comfort and venture into the unknown.
