Meet the latest GXR a.k.a. Kevin

One of the first gravel-specific bikes to be sold in the mass market, the Curve GXR model has been around since gravel became cool. 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.

Maximum Versatility

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. To make sure current, prospective or custom bagging fits your frame size please see our Bagmaker Drawing page.

Nice upgrade 51mm for me
Color: Silver
This is my second 51mm machine. I never used the included handle or basket… I kept my existing HUGH IMS precision basket and bottomless portafilter. The temp and preinfusion are set and not adjustable but fine (reduced variables). I defeated the shut off by volume by setting higher than needed (wish that was easier to turn off). I like to manually shut off when I hit 30g on my scale. The machine will drip since there is not solenoid valve so I just pull the scale from the try when mouse tail breaks and drip starts. The steam wand and hot water dispenser is a massive upgrade (from Capresso EC50) and the real reason for my upgrade. I would have paid $50-100 more for the improvements listed… but I guess most people would not so this is about the best option for me with 51mm (keeping all the 51mm three lug portafilter stuff I own). 5 stars = for me and the price

Reliably makes a good cup of coffee!
Color: Rose Golden, Color: Rose Golden
This espresso machine is great. I wanted something simple and reliable and that’s exactly what it is. In fact, the espresso comes out with a nice creamy coffee froth on top and the flavor is excellent. I don’t normally write reviews, but I think this one is worth it and I want them to stay in business because I’ll probably be sending some of these out as gifts come next Christmas.
