GMX+ Steel and Ti FAQs

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.

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.
