The Curve GXR4 builds on the success of the original GXR Kevin as a fantastically capable gravel bike and all round adventure bike. We have sent customers off for adventures all over the globe, from the Tour Aotearoa, the Tour Divide, Race to the Rock, or the Wilds of Mongolia! For 2025 the bike gets a few important updates, increased tyre clearance to run 700x50 frame and fork, internal dropper cable touring, increased stack and standover on most sizes, revised chainstays scale for different sized bikes and a new UDH compatible rear hanger give drivetrain options down the line.

Any out of stock options available to test ride/order in 3-4 weeks. We can swap in the wheels of your choice, so please contact us if your desired option isn't in stock on the website.

  • Wide Tyre Clearance

    The GXR has been designed with gravel cycling versatility in mind. While the GXR geometry is optimised for 700c x 44mm tyres, you can go as wide as 50 mm tyres on 700c wheels. In 700c mode with narrower tyre options, Kevin is ready for fast gravel missions, but you’ll be surprised how capable Kevin is on chunkier terrain with a 50 mm tyre. With 650b (27.5”) wheels you can move into gravel-plus territory with 2.2” tyres which offer plenty of comfort for the most rugged gravel adventures. Curve has the above wheel options in carbon and aluminium available and ready for complete Kevin builds.

  • 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.

It works!
Size: 1 Count (Pack of 1)
My 2005 Jetta failed the inspection and my mechanic said (after clearing the engine light) that I should drive the car for 20 min highway and 20 local. We've tried that the whole day but out of three lights on his device only 1 went away. Next day the light engine came back. After not being happy with the explanation offered by him (a family friend) that I should keep driving it until we get lucky I went online and found CRC 05063. Followed the instruction (one bottle on full tank of gas). Before my tank was under 3/4, engine light went off!! At half tank I went and did the inspection - IT PASSED! I am really impressed! Update August 2015! I have been using this product for 2-3 years now and if it is not working for you please read. In July I have used the first bottle and took my 2005 Jetta for inspection. It failed. Ordered a second bottle and it failed again. My mechanic said keep driving. Did 200 miles in one day and nothing. Decided to take matters in my own hands and ordered Autel MaxiScan MS300 ($18, it allows you to read and delete codes). There were two faults - EVAP and 2nd something about Oxygen. Went online and this is the first time I heard about driving cycles. These are steps that you have to follow so that your car's computer can start measuring all the parameters needed for the test. Driving cycles are not exact science but I tried to follow the instructions as much as I could and after just 20 minutes (10min city and 10min highway) ALL the parameters were set and I passed the emission test with flying colors! So, just before you give a comment about CRC like "tried and didn't work" be aware that there are other things you have to take into account.

This product never fails (no pun intended), I have been using this for the last 10 years my car has never failed a smog test. I highly recommend this and that you use it correctly. You will not be disappointed.

Really Helps-Especially for Star Station Tests-Haven’t Failed Since Using in Two Older Vehicles
Size: 1 Count (Pack of 1)
Ever since the new CA State mandate that older cars and trucks have to go to a Star Emissions Station for their smog check I have become very familiar with Guaranteed to Pass. The first year of getting smogged under the new regulations my 1995 truck barely failed. It’s a tougher series of tests and it really sucks to have to pay more for a smog test that is designed to get older cars and trucks off the road that would normally pass a regular smog check. It came at a bad time, having just been laid off and losing my health insurance and income and trying to figure how to come up with money for truck repairs to get my registration renewed so I could be a viable job candidate in the really bad job market of a few years back (and still today, may I add.) But that is a whole other issue that gets my blood boiling. So back to my experience with Guaranteed to Pass. My 1995 Ford Truck barely failed and I mean barely according to the emission numbers so I had the manifold cleaned out, used premium gas for a tank and added Guaranteed to Pass. Having two gas tanks was handy as I could switch the tank to a fresh tank without the remainder of the additive in it for the retest. It passed with flying colors. So for our other older 1993 mini-van and the truck in the few successive years since I always run the premium gas with Guaranteed to Pass in the tanks before the smog check. We’ve had the van and truck tested 3-4 times combined since and they pass every time. So I’m sold on Guaranteed to Pass and will vouch for it.
