V4 UPDATES
The CXC has been updated and it is now in its 4th iteration. With this new edition we have swapped the brake mounts for Flat Mount.
We have also swapped the traditional binder bolt for af collar that adds a more strength and replaceability should any thing brake.
A SWISS ARMY KNIFE
Meet the Omnium CXC, our most adaptable all-rounder. It’s built for riders who want a bike that handles city commutes, all road, and weekend adventures with ease.
The CXC combines the quick, responsive feel of a track bike with the clearance and mounts of an all road setup. It’s tough, agile, and ready to ride anywhere you want to go.
Made from triple-butted steel, the frame balances everyday durability with a responsive feel. It’s ED-coated for extra protection against the elements, so you can ride year-round without worry. Adjustable rocker dropouts and a belt split let you choose your setup — geared, single-speed, or belt-drive.
The segmented steel fork is designed for disc brakes and features triple cage mounts on both legs, giving you plenty of space for bottles or bags when you’re loading up. Add racks, fenders, and wide tires — the CXC is built to adapt to your needs.
Whether you’re tackling your daily commute, exploring back roads, or hitting the track, the CXC delivers a fast, agile, and reliable ride every time.
SPECS
GEO
Run full mudguards and up to 45mm tires, racks, bags and go camping, or strip it down and mash out some kilometers of mixed terrain in turbo mode. There is nothing more versatile.
Getting the perfect fit makes all the difference in how your Omnium feels and performs. Use the chart to find the frame size that best matches your height.
Each Omnium frame size covers a range of rider heights, so if you’re between sizes, consider how you like your bike to feel:
- Choose the smaller size if you prefer a more agile, responsive ride.
- Choose the larger size if you want a more stable, stretched-out position.

BUILD NOTES
Brake Standards
CXC frame kits come standard as flatmount – Inserts can be swapped for post mount – this will not change the front brakes mount that will still be flat mount, but you can easily buy a flat to post mount adaptor.
Headset & Fork Compatibility
Frame kits requires a standard 1 1/8 headset for straight steerers, make sure to check the spec sheet for the correct sizing of the headset and take note that replacing the fork whilst most carbon forks have a tapered steerer straight steerer carbon forks are still available, so make sure to check the specs for a replacement fork to ensure compatibility.
Drivetrain
Any 1×11 speed and newer gravel drivetrain from Shimano or Sram will provide compatibility and great shifting. Avoid MTB specific cranksets.
Shimano Cues or Microshift Sword are also great options for a 1×10 speeds groupset.
Made for 1x: whilst we offer a derailleur stop for 2x there is no routing for it on the frame, and you will have to figure out compatibility for the parts you want to install.
Tyre Clearence
CXC’s have a max tyre clearence of 45mm.
