Aerodynamic Focused

The design of the Bigrock Aero is super aero focused.

The headtube is hourglass shaped, reduced the projection area and still allowing cables to be fully integrated. They have made a smooth transition from the fork to the downtube, which means the airflow to pass through the frame more smoothly and faster.

The seat tube has made to fit the rear wheel better, reducing the intersection of air resistance, thus achieving a more aerodynamic effect.

More Than Aero

Besides the aero tube shape, the down tube of the Bigrock Aero also come with a hollow on the top to shape around a water bottle. On the rear of the frame, the seatstays are moved to a lower position to increase comfort of the bike.

Affordable doesn't mean "Cheap"

While the Bigrock Aero is on the more affordable end of the spectrum, it’s quality and finish are far from “cheap.” The paint work is beautiful, mounting points have been finished with care, and the included accessories put many big brands to shame.

Bigrock Sohtea TEAM EDITION Carbon Road Bike Frameset

Joe Whittingham — Tue, 20 Feb 2024 06:10:44 +0000

BIGROCK Sohtea: A no-nonsense modern classic

The Bigrock Sohtea is a modern take on a classic concept, wrapped in a super light package. Disc brakes and fully internal cable routing make it ready for today's hydraulic electronic groupsets, while a traditional double-triangle frame design with a shorter seat tube is a throwback to the compact road bike design of yesteryear. The advantage of this design is a better stiffness to weight ratio of the frame while offering more compliance to the saddle due to the increased length of exposed seat post.

Specifications

Frame Material: Mitsubishi T1100 + T800
Thru Axles: Front: 12×100, Rear: 12×142
Headset: 1-1/8″ to 1-1/4″ (Included)

Front derailleur: Bolted on front hanger
Tire clearance: Max. 700*30C

Sizes: XXS (45), XS (49), S (52), M (54), L (56)

A simple design, well executed

Sometimes the bike industry gets ahead of itself, designing bikes more and more complicated in the name of marginal gains.

The Bigrock Sohtea takes things back to basics. Two triangles, round tubes, nice and light.

The result? A suprisingly stiff bike for it’s weight that has balanced handling and plenty of compliance in the saddle.

More Seatpost, More Comfort

On most road bikes today, shorter riders are left with tiny amounts of seat post sticking out the frame. This creates a harsh, uncomfortable ride with the short length of seat post unable to absorb the bumps. By shortening the seat tube, the Sohtea leaves more exposed seat post providing more comfort to the rider. Once you get used to the “strange” appearance, it starts to make a lot of sense…

Team Edition

While the Bigrock Sohtea is on the more affordable end of the spectrum, it’s quality and finish are far from “cheap.” The paint work is beautiful, mounting points have been finished with care, and the included accessories put many big brands to shame.

Size L (56) : 675g ±5%

Front fork: 285g ±10%

Note: These are the official weights provided by Bigrock. They claim they exclude alloy parts. We suspect this also means they exclude the T47 thread insert. Therefore, we expect real-world frameweights to be about 60g more than these official weights. (Including T47, front and rear mech hangers.)
