Meet our GXR a.k.a. Kevin

Our titanium GXR, paired with the Ride 400 carbon fork has been tested heavily on adventures worldwide. Many of the Curve team have traversed South America, New Zealand, Switzerland, Swaziland, and more on this magnificent bicycle.

Originally a playful jab at the bike industry's bike naming terminologies, the name ‘Kevin' was coined to name this frame. it soon caught on, and we simply couldn’t resist making it official.

  • Two Bikes in One

    The Ride 400 carbon fork has clearance for wheel options based on your riding style. For example, Kevin can run either 700c wheels with 32–45 mm tyres, best suited for commuting, gravel, and cyclocross, or if you’re looking to tackle some rougher terrain with more traction, use 650b (27.5”) wheels fitted with 1.8–2.2” tyres. Curve has the above wheel options in both carbon and aluminum available.

  • No Weird Flex

    The custom titanium yoke design allows Kevin to run some super-wide gravel tyres in two wheel sizes and stiffens the BB area to avoid frame flex under load.

  • More Mounting Points

    Kevin comes equipped with rear rack mounts, fender mounts, and 3 x bidon mounts; and can run either a 1x or 2x drivetrain. Kevin is ready for single or multi-day bikepacking adventures due to extra tyre clearance, a longer wheelbase, and a more stable platform.

  • Ready for Adventure

    Our Ride 400 fork, originally titled GXR fork, was built to complement the Kevin of Steel and titanium GXR frameset. Featuring 3 x 12 mm M5 mounting points on each blade, the Ride 400 fork can accommodate anything from extra water bottles, our Rocket Pooches, or any other micro pannier or fork-specific bag.

    There is ample room for bikepacking bags on all frameset sizes. To make sure current, prospective or custom bagging fits your frame size please see our Bagmaker Drawing page.

  • Want to Carry More?

    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.

A Love Letter to Kevin

Dear Kev,

When we first met, over three years ago, I directly knew that you weren't like the other bikes. Behind your sober and classy titanium façade was hiding enormous potential...

2 Kevins in one family

We are the proud owners of two Kevins one a blue Kevin of steel with 11 speed Sram and the other a Ti Kevin with 12 speed Sram AXS E-Tap. I cannot fault either bike and the Ti Kevin with Sram AXS 12 speed paired up to a 40 tooth crank and 10-52 cassette is the ultimate do anything bike, Two wheel sets one 700C running 32mm Conti GP 5000 and 10-42 cassette for the road, 700c Curve Gravel wheel set with 40mm Gravel Kings for fast gravel and 650B and 2.1" Maxxis for single track and steep goodness covers everything Im likely to ever need.

This bike can do anything

Look, I only went into Curve HQ to buy some wheels. Instead, I came home with Kevin (Rhino is very convincing) and it is fair to say he has changed my life.

I’ve raced the Pan Celtic, crossed New Zealand, numerous grand fondos on road and gravel, commuted to work, hit the MTB trails, been bikepacking - all on this incredibly versatile bike. I have no doubt that we have many more adventures to come.

On top of that, you get amazing service from the Curve crew who have built an amazing and inclusive community. These guys truly live their values, and are always there to help with any questions and advice you might need.

Best bike ever

I’ve had Kev for over 5 years now and it’s simply the best bike ever.

Whether it’s racing cyclocross, smashing out high country road climbs, endless gravel, loaded bike packing, shredding gnarly single track, or commuting to work, this is the best bike ever. Just change the tyres to suit the activity, or do what I did recently and get the second wheel set with a dynamo hub.

Add in a custom paint job and it’s the dream bike for every occasion.

Shout out to the Curve crew too who are all very friendly and attentive to endless questions about all things bikes and adventures.

Ian Creighton
A friend for life.

Kev has been such a reliable ride. He can get rowdy when you put his party shoes on, he can go fast when fling skinny tyres on or he can help you ride off into the sunset in supreme style and comfort.

Kev really is a bike for life and with each passing year I get to know him even better.

Kevin is the best

I’ve had Kevin less than 3 months and I’m in love! I was so excited the day I picked him up, like a kid a Christmas - hence the Christmas jersey worn on NBD 🎄

I’ve taken Kev bikepacking, on Audax rides and Curve weekly and monthly rides. Kev has done wonders for my confidence on gravel. He is stable, comfortable and reliable. He gets ALOT of attention, stunning bike that he is! Curve is not just a bike brand but a community, fun, inclusive, empowering and knowledgeable. Not only do I love Kev but the community that I feel a part of(even before I had a Curve bike). Only downfall is Kev loves a photo so be prepared to stop for lots of pics!
