Big Kev V2

A larger diameter means more comfort on rough terrain. A smoother ride is also more efficient. The modern gravel race scene has taken this to heart, with pro riders lining up with the widest tyres possible on their frames.

With Big Kev v2, we have committed to the 29-inch wheel platform. With the new Ride 415 VGM carbon fork, Big Kev v2 is optimised for 2.25” tyres, with a maximum width of 2.4”. For sizes SM and up, you can even fit 2.6” tyres with limited mud clearance. Big Kev is sure to quench your wide tyre gravel bike thirst.

For less rugged missions or extra speed on fast gravel tours, you can slim down to 2.0” tyres for faster rolling. Gravel-plus means you can take on more than just pristine gravel roads. Big Kev v2 gives you the flexibility to get more adventurous.

With a titanium tubeset carefully selected and finely tuned for weight, comfort and reliability, Big Kev v2 is built to last. We’ve proven this with industry-standard MTB-level testing.

The detailing on Big Kev v2 takes Curve bikes to the next level. A custom yoke, with asymmetrical chainstays and dropouts, allows super wide tyre clearance with a road Q-factor. This exquisite yet complex rear-end, tied together with an 85.5mm T47 bottom bracket shell, provides a sturdy platform under load. The refined dropouts use the SRAM Universal Derailleur Hanger (UDH) system and are fully compatible with SRAM Transmission derailleur systems.

Let’s face it, to tackle the biggest bikepacking adventures with confidence, you need a bigger tyre. A narrow gravel tyre won’t cut it – no one wants to slash a sidewall on day one or walk a bike up a rocky climb due to lack of traction. Big Kev gives you all the benefits of a drop bar setup, but with the comfort and traction of a gravel-plus tyre.

Whether it’s single-day gravel missions, multi-day flashpacking, or racing the Tour Divide, Big Kev is ready for whatever cycling mission you have planned.

Big Kev is built with a larger main triangle compared with other 29er options. This allows full-size frame bags for extra storage, even on smaller sizes. With three bidon mounts, rear rack and fender mounts, and 1x groupset options (boost cranks are not required), Big Kev has a variety of riding styles covered.

Our Ride 415 VGM fork has offset adjustability to fine-tune your ride. In addition, the 3 x M5 mounts on each leg allow you to carry fork-mounted bags or extra bottles. Rated to carry up to 8 kg on each fork leg, this class-leading fork is amazingly robust.

With a wide range of frame and fork-mounted rack systems on the market, and with more appearing every week, it is important to understand which rack systems are compatible with your Curve frame and fork, and how to mount them correctly in order to ensure safe riding, avoid damage and voiding your warranty. Before mounting a rack, we strongly recommend you get in touch with us to confirm compatibility and the correct mounting procedure. This will minimise the risk of injury, product damage and voiding your warranty. Your local Curve dealer, or the team at Curve HQ, can also help you select a rack system and mount it to your bike for you.

The Big Kev features Bento Box mounting points on the top tube, allowing you to secure your belongings in most bolt-on top tube bags. 

For even more carrying capacity, a framebag might be the way to go. To make sure current, prospective or custom bagging fits your frame size please see our Bagmaker Drawing page.
