Meet the latest GXR a.k.a. Kevin

One of the first gravel-specific bikes released, the Curve GXR model has been around since well before gravel became cool. Now, with wider tyre clearance, improved mounting options and UDH compatibility, the latest version of our Swiss Army Knife of bikes is more versatile than ever.

We have been ahead of the Curve when it comes to gravel, and the GXR has years of adventure cycling experience woven into its DNA. The Curve titanium GXR has been tested heavily on gravel adventures worldwide. Across South America, New Zealand, Switzerland, Swaziland, and more, the Curve squad has traversed the globe on this magnificent bicycle. 

Originally a playful jab at the bike industry's bike naming terminologies, the name “Kevin” soon caught on, and we couldn’t resist making it official. Kevin, the reliable Aussie all-rounder, is here to stay as a permanent nickname for our beloved GXR.



  • Wide Tyre Clearance
    The GXR4 has been designed with gravel cycling versatility in mind. While the GXR4 geometry is optimised for 700c x 44mm tyres, you can go as wide as 50 mm tyres on 700c wheels or 29 x 2.0" on our Dirt Hoops.
    With wider tyres being all the craze currently, Kev is set up ready to crush almost any trail!


  • Ready for Adventure
    Our Ride 415 VGM fork has taken load carrying to the next level, with a 8 kg rating on each fork leg. That’s a total carrying capacity of 16 kg. Featuring three cleverly designed mounts on each fork leg, the Ride 415 VGM fork can accommodate anything from extra water bottles, our Rocket Pooches, or other micro-pannier or fork-specific bags.
    While we favour 1x drivetrains, Kevin can be set up with a 2x drivetrain without hassle. With SRAM UDH compatible dropouts, Kevin is able to handle the widest range of groupset options currently available.


  • More Mounting Points
    The Curve Kevin comes equipped with rear rack mounts, fender mounts, 3 x bidon mounts, and top tube “bento mounts”. With extra tyre clearance, and a comparatively long wheelbase for the gravel genre which offers a more stable platform, Kevin is ready for epic day rides or multi-day bikepacking adventures, not just smooth gravel cruising.
    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.

Soft, fluffy and surprisingly comfortable
Color: White, Size: Queen (Pack of 2), Color: White, Size: Queen (Pack of 2)
I really liked these pillows. I tried to show different things in my photos because I wanted people to see the details: the design, how fluffy they are, and how full and thick they actually look. They are so full that the pillowcase even looks tight once you put it on, which I actually loved because they look luxurious and well-filled. At first glance they look very thick and high, but once you lay down they feel soft and fluffy instead of hard. They adjust comfortably and feel very cozy whether you’re sleeping, relaxing, or even reading before bed. I think they offer a really good balance because they feel supportive without being stiff. Of course, pillow preference is very personal—some people like lower pillows and others like higher ones—but for someone who likes fuller pillows that are still soft and comfortable, these are great. They are spacious, cozy, and feel like a very good purchase overall. I honestly don’t have any complaints so far. Definitely happy with them.

Great quality pillows. Very difficult wrapping.
Color: White, Size: King (Pack of 2)
The Pillows are the real deal. Very fluffy but with good support. I was surprised by the weight of the box they came in, pretty heavy so you know there’s good quality pillows inside. The one negative is that the pillows are packed in very very tight plastic because they come compressed. But the thing is, it’s really a chore to open them. You have to be careful not to cut through the plastic to the material, but the plastic is put on so incredibly tight that it’s even hard to get your finger underneath. But I found a way to open them. Near the top, insert A very flat metal ruler as far in as you could get it. Then cut through the plastic that’s above the metal ruler. That prevents a sharp tool from damaging the pillows. As you get through the plastic above the ruler, keep pushing the ruler further down into the package. Believe me, this simplifies what could be a very difficult unpacking. I am very surprised that the company that makes them does not insert the type of opener that you find on boxes you receive in the mail or even packages that you get from the grocery store where you just pull a tab and that opens the package. These are really good pillows, but you must be very careful about using a sharp object when opening the box and when trying to cut through the plastic. I am a strong man and have the tools needed, a very flat metal ruler, and a box cutter, knife, or razor. Good luck. !!

These hold up very well
Color: White, Size: Standard (Pack of 2)
I have NO luck with pillows. I’ve been in stores & tried them. They seemed ok there. At home, nope. I’ve been getting headaches & neck aches from lousy pillows. I’ll change one, a few nights relief. It doesn’t help that I’m prone to headaches. After reading about different pillows, I settled on these. The reviews were better than so many different ones I was looking at. Including high priced & brand names. I bought the standard size. When I saw, “Customers Usually Keep This”, I kept my fingers crossed. When I received them, I took one out of the package & put my head on it & thought, oh no! This is too hard! I tried it again. Ok….. I slept on it & haven’t had any pains since. It’s soft but firm enough to keep my head from sinking & messing up my neck. I don’t move. No more flipping my pillow over. My head doesn’t go below my neck anymore! This has been 2 months now, but it hasn’t changed at all. I wake up happy, not complaining. No more pains or headaches. This saved me from losing days with a heating pad or an ice pack. The price was excellent for 2 pillows. I can’t believe a blind buy was the answer! These are incredible. Finally, something worked for me.

Awesome Pillows!
Color: White, Size: King (Pack of 2)
These pillows are super soft! I love them. I bought them when I caught a bad cold and needed to prop myself up. Worked so great! Definitely give these pillows a try. They're very reasonably priced too.

Comfortable, Hypoallergenic, and Great Value
Size: King (Pack of 2), Style: Soft, Configuration: Pillow
These pillows are a solid upgrade for everyday sleep. They’re soft but still provide enough support for both back and stomach sleeping, and the down-alternative fill is perfect if you’re sensitive to allergens. The microfiber cover feels smooth and well-made, and they fluff up nicely after decompressing. Overall, a comfortable and affordable set that gets the job done.
