ENVE MOG SRAM AXS Custom Bike — this is where gravel gets personal. The MOG, short for Mother of Gravel, is ENVE's statement on what a no-compromise gravel bike should be: fast on hardpack, confident on singletrack, and refined enough that you actually want to put in a century on mixed terrain. And with RA Cycles' custom bike builder, you are not just buying a MOG. You are speccing it out exactly the way you ride, choosing every component from groupset to wheels to finishing kit, seeing it all come together on screen, and getting a fully built machine delivered to your door.

ENVE is not a brand that does things halfway. They have been making some of the best carbon fiber components in cycling for over two decades, and the MOG is what happens when that obsession with layup quality, ride feel, and real-world durability gets focused into a complete gravel platform. The frame weighs a claimed 950 grams in a size 56, which is seriously light for a gravel bike built to handle 50mm tires and loaded adventures. That is not a fragile race frame pretending to do gravel. It is a legitimate gravel bike that just happens to be built like a thoroughbred.

What really sets the MOG apart is how thoughtfully it addresses the things gravel riders actually deal with. Tire clearance up to 700c x 50mm means you can run big rubber for backcountry stuff and swap down to a fast 38mm setup for gravel races without needing a different bike. The geometry is optimized around a 42mm tire, so it feels balanced and predictable whether you are pushing pace on a road section or descending a loose fire road. And ENVE designed three different fork rakes across the six frame sizes, which means a size small handles just as naturally as a size large. That kind of attention to size-specific tuning is rare.

The Builder: Your Bike, Your Way

The RA Cycles custom bike builder is the centerpiece of this page. Think of it as your workbench. You start with the ENVE MOG frameset and then choose your SRAM groupset — Red AXS for the lightest, most refined experience, Force AXS for the performance sweet spot, or Rival AXS for a build that punches well above its price point. Every one of those groupsets brings wireless electronic shifting, which means clean cable routing, precise shifts under load, and zero cable stretch over time.

From there, you pick your wheels, tires, handlebars, saddle, seatpost, and everything else that makes a bike yours. The builder shows you component pricing in real time, so you always know where your build stands. You can see what each choice looks like on the bike, compare options, and make swaps until it feels right. The goal is to give you the same kind of control you would have standing in the shop with a mechanic, except you can do it from your couch at midnight if that is when inspiration strikes.

Technology That Matters

The MOG is loaded with the kind of details that make a difference once you are actually riding. The ENVE Cargo Bay is an integrated downtube storage system — two neoprene bags that tuck inside the frame, giving you 36 cubic inches of space for a tube, CO2, multi-tool, or whatever else you want out of sight and out of mind. No rattling, no added bags, just clean storage that is always there when you need it.

ENVE's IN-Route cable routing system hides hoses and wires from the wind, improving aerodynamics while keeping the cockpit clean. The frame uses a threaded T47 bottom bracket, which is the gold standard for creak-free performance and easy serviceability. The 27.2mm seatpost diameter gives you natural compliance over rough terrain without bolting on extra suspension gadgets. And the flat-mount disc brake standard means you are running the most current braking platform available.

What Happens After You Build

Once you finalize your build and check out, your card is placed in authorization status only — RA Cycles does not capture payment until your final spec is confirmed and timelines are reviewed together. An RA Custom Studios consultant will reach out by email or phone to walk through every detail, discuss any special-order items, and confirm your build. This is not a faceless transaction. You have a real person making sure everything is exactly right before a single part gets pulled from the shelf.

Every custom build includes professional assembly, complete quality control, and careful packaging for safe delivery. When your bike arrives, it will need minimal setup — a torque wrench and a few minutes is all it takes. And if you hit a snag during assembly, your RA Cycles specialist is a FaceTime call away to walk you through it. For riders near Brooklyn, Walnut Creek, or Miami, you can pick up in person and ride out the door.

Cannot Find What You Want? We Can Still Get It.

The builder offers thousands of component options, but cycling is a deep world and sometimes the exact saddle, bar tape, or wheel you want is not in the configurator. That is not a problem. Reach out to the RA Cycles team and they will source it, price it, and work it into your build. The builder is a starting point, not a limitation. If it exists in the cycling world, there is a very good chance RA can get it on your MOG.

Lead Times and Delivery

Custom builds are exactly that — custom. Lead times are not calculated automatically in the builder because every build is different. Some components are in stock and ready to go. Others might be special order. What RA Cycles is known for is working hard to get you on your bike as quickly as possible. We have been doing this since 1976, and the relationships and inventory we have built over nearly five decades mean your build will not sit in limbo. Your consultant will give you a realistic timeline during the post-checkout review, and they will keep you updated along the way.

Financing Your Build

A custom ENVE MOG is an investment in your riding, and RA Cycles offers flexible payment options through Affirm, Klarna, and Shop Pay. Depending on approval, you may qualify for 0% APR financing, which lets you spread the cost over time without paying a cent in interest. You can explore financing options during checkout.

Final Take

The ENVE MOG is one of the most capable and refined gravel frames on the market, and building it custom through RA Cycles means you get exactly the bike you want — not a stock spec sheet someone else chose for you. Whether you are racing Unbound, exploring backcountry fire roads, or just want one bike that does everything on dirt and pavement, the MOG with SRAM AXS wireless shifting is a platform you can build a lot of adventures around. Use the builder, make it yours, and ride something that was put together with intention from the first click to the final torque spec.
