FiftyOne Bikes founder Aiden Duff says they’ve constructed sufficient customized street bikes for various riders that they common 10 distinctive bike designs each month, greater than many manufacturers do in a number of years.
Now, he’s distilled all of that knowledge into the brand new FiftyOne Sika, a top-level street bike designed for actual riders, not skilled racers. It’s nonetheless excessive efficiency, however with clearance for 40mm tires, assured dealing with, and a much less excessive using place.
However, Duff says that doesn’t make it an “endurance” bike, that it’s very a lot a efficiency street bike. It will get aero touches, excessive backside bracket stiffness, and may be very mild. Claimed weight is simply 690g!
That makes sub-7kg full bike builds, with pedals, totally potential. Duff mentioned being extremely light-weight wasn’t the aim, however a cautious choice of high-level Toray fibers allow them to hit their stiffness objectives, use aero-optimized tube shapes, and nonetheless make it actually mild.
Experience high quality is enhanced by the bigger tires (if you need them, it really works nice with 28-32mm tires, too), plus a regular spherical 27.2 seatpost and added fork compliance. Their “actual rider” geometry provides it a bit shorter attain and chainstays which are a number of millimeters longer than what you’d discover on a race bike.
The one-piece bar/stem is their first in-house cockpit design. It has NACA airfoil shaping with a barely 3º backsweep to make it and also you a bit of extra aerodynamic. All cables and hoses run internally for a full stealth look.
Lastly, it makes use of a T47 threaded BB and a UDH hanger for stable future element compatibility and simple service.
