The reach on the geo chart looks long. What size is good for me? |
The short answer is that the reach number may be somewhat deceiving as the frame is designed to be run with a shorter stem. That, in combination with the comparatively steep seat angle, reduces the effective reach of the frame. Please reach out to sales@curvecycling.com if you have any questions about sizing. Read more about the GMX+ geometry here: GMX+ Geo Blog |
| Why flat mount? |
There are very few drop-bar groupsets available with post mount calipers, so we decided to introduce flat mount on GMX+ Steel to make the groupset selection for drop bar setups easier. |
| What are those black brackets on the downtube for? |
In order to reduce the number of holes and M5 mounts added to the downtube, and to add stability to the offset mounts, we decided to make these offset mount support guides specifically for the GMX+ Steel. These guides must be used when attaching bottle cages to the offset mounts. |
| What are the extra plates with three holes I got with my SM or XS frame? |
These are adapter brackets for the rear M5 mounts so you can attach a regular bottle cage to the back of the chainstays and seatstays. The plate is not needed for sizes MD and up. |
Italian Steel -
The main frame triangle is comprised of Italian-made double-butted Columbus Zona tubing. Zona allows for the ideal compromise between weight, strength and life of the frame.
Two Bikes In One -
The GXR's carbon fork, the Ride 400, 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 aluminium available.
Big Tyre Clearance -
The custom 4130 steel yoke design allows Kevin to run wide gravel tyres in two wheel sizes without tyre rub. Up to 45mm for 700c, and around 2.2"/55mm for 27.5"/650b. Clearance may vary depending on your choice of tyre tread.
Ready For Adventure -
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 light single or multi-day bikepacking adventures thanks to generous tyre clearance and balanced geometry that produces a stable riding platform.
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.
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.
* A "lowering" braze-on adapter may be needed to fit a front derailleur without interfereing with the bottle bosses. Contact us for info.
