Technical Specification

Tern Eclipse P20 FOLDING BIKE

The Eclipse P20 is a high-performance road bike that folds down fast. With custom 26” Rolf Paired Spoke wheels, a 250 mm Physis™ 3D handlepost, and performance-tuned frame geometry, the Eclipse P20 is engineered for speed. It sports a stealth black finish and hydraulic disc brakes.

OCL™ FRAME JOINT

The key to any folding bicycle is the frame, and specifically, the folding joint at the heart of the frame. Done well, it locks the two halves of the frame together without any hint of movement or sound. It should be easy to operate and work flawlessly year after year. The OCL Joint does all of these things and is a new reference in folding frame technology.

TARSUS™ FORK

Utilizing a single hydroformed tube mated to a precision-machined steerer, the Tarsus delivers superior strength in a shape that matches the sophisticated lines of the Verge and Eclipse frames.

PHYSIS™ 3D HANDLEPOST

Five patented technologies and unique manufacturing technology add up to the strongest, stiffest folding handlepost available. The Physis uses a special manufacturing process called 3D forging, which forms the post from a single piece of aluminum, eliminating all welds.

SYNTACE VRO STEM

Your bike should adapt to fit you―not the other way around. This adjustable stem allows you to position your handlebars further, for a more stretched and aggressive riding position, or up higher for increased comfort.

TEKTRO HYDRAULIC DISK BRAKES

When you’re going fast, in all sorts of weather conditions, you need brakes that work, and work well. Tektro hydraulics fit the bill with sure, single-finger stopping power.

KINETIX PRO DISC WHEELS

Paired-spoke design allows us to build a strong wheel with fewer spokes—resulting in a lightweight, aerodynamic wheel for fast riding.

SCHWALBE KOJAK TIRES

Light and fast tires with enough volume to keep things comfy. Kojak’s are ideal for fast commutes or longish weekend rides.

SHIMANO TIAGRA 2 X 10 DRIVETRAIN

To give you awesome climbing gears while maintaining downhill speed, we pair an 11-32T cassette, compact double 50/34T crankset, and Shimano Tiagra derailleurs.
