FiftyOne SIKA Sram Red AXS E1

The Sika is a cutting-edge road bike that delivers top-level performance in a package tailored for real riders, not for pros. It combines feathery lightness, high stiffness and sleek aero with a less extreme position, confident handling, and clearance for 40mm tyres. It’s the ride of your life, all day long.

 

KEY FEATURES

 

690g frame weight, size M

Float up the mountains on one of the lightest bikes in its class. A sub-7kg build is easily achievable.

 

 

40mm tyre clearance

Conquer bad roads, cobbles and even gravel with the option to run tyres up to 40mm in width. Road bike tyres have been getting bigger at a rapid rate in recent years. While 30 and 32 are the new norm, riders who live in areas with worse roads already want even wider tyres. The Sika is ready for anything, including the future.

 

 

Real world rider fit

We built a bike for normal people who want to ride all day, not pros wanting an extreme position. Drawing on our experience of building hundreds of custom bikes, and on our relationships with the world’s best bike fitters, we shaped the Sika to be comfortable for the vast majority of riders, without requiring an unsightly stack of spacers or ruining the bike’s elegant proportions.

 

 

Sika one-piece cockpit

Ergonomics and aerodynamics harmonise in our first cockpit, designed entirely in-house. The top section is shaped with proven NACA profiles to deliver a significant aero gain in this critical area that meets the cleanest airflow. The tops also sweep back at a 3-degree angle for a natural hand position. Brake hose routing is fully internal.

 

 

T47 bottom bracket and Universal Derailleur Hanger

Secure, quiet and serviceable for life, the T47 standard, invented by Chris King, uses a threaded metal shell. It’s loved by mechanics and by riders weary of creaking pressfit BBs. The SRAM UDH is the easiest to source and replace should you need to, wherever you are. These are common sense choices.

 

27.2mm round seatpost with traditional external clamp

The most comfortable and practical solution. A round 27.2mm seatpost is able to flex more than any aero-shaped post, adding comfort at the saddle where it matters most. We decided this was more important than a small aero gain. The round post also gives you the freedom to choose any post, rather than being stuck with a proprietary design. We chose a traditional clamp because they’re so much easier to live with, especially if you travel with your bike, compared to a hidden wedge that usually binds in place.
