Next level frame

The P Line titanium rear frame and forks are 700 grammes lighter than the all-steel equivalent and are just as strong. The redesigned suspension block maximises efficiency and responsiveness by shifting your pedal power to improve control and handling performance. Naturally, shock-absorbing titanium smooths out the road. You can feel the difference.

Enhanced portability

Moving with this bike is easy. Our new dual-locking seat post system has two positions, fully down for storing or halfway up for rolling. The folded bike gently steers through tight busy spaces with the Superlight Saddle nose handle. Larger, lighter rolling wheels glide over uneven ground.

Superlight, compact gear system built for the city

Designed in-house, the new superlight compact gearing system* is fine-tuned for city riding. The 4-speed system with an all-new 60-gram derailleur is meticulously engineered to fit inside the narrow fold. Delivering a similar ratio to the 3-speed and 60% more than the 2.

All-new wheelset

Our lightest, sturdiest wheelset. With a new rear hub designed ground-up to accommodate the new compact 4-speed gear set. Tested on a purpose-made rig and fired with mud, water and sand for hundreds of hours. This wheelset stands up to the abuse of the city. Now fitted with hex key axles and a new hanger mount, so removing them for roadside repairs or maintenance is quick and easy.
