First, choose your frame size (top tube length). Once you have that, then choose your front end height (or frame stack height) to dial in your perfect fit.
Three Rider Fit Profiles
We offer three distinct fit profiles in 12 sizes each.
Fit Profile
Fit Description
Position Variants, relative to the other two fit profiles
A neutral fit position for gravel riding. Our most popular geometry works well for the majority of riders. Similar to the industry's common gravel bike fit.
Slightly more upright and shorter than our standard gravel position. Better for long rides where comfort is as important as performance. This fit profile can also be better for exploring unknown territory.
Compared to our Standard Fit:
The front end height and handlebar position is about 3.0 cm (1.2") higher.
The reach from saddle to handlebar is about 1 cm (0.4") shorter.
Slightly lower and longer front end than our standard gravel position. Better for aggressive rides where speed is the goal and comfort is not of concern.
Compared to our Standard Fit:
The front end height and handlebar position is about 3.0 cm (1.2") lower.
The reach from saddle to handlebar is about 1 cm (0.4") longer.
Standard Fit Frameset Geometry
Seven's Standard Fit Profile: A neutral fit position for gravel riding. Our most popular geometry works well for the majority of riders. Similar to the industry's common gravel bike fit.
Choosing the right size: If you need help deciding which fit profile and size you should ride, visit a bike fitter to determine your ideal size. Seven does not make size recommendations remotely.
Seven's Endurance Fit Profile: Slightly more upright and shorter than our standard gravel position. Better for long rides where comfort is as important as performance. This fit profile can also be better for exploring unknown territory.
Choosing the right size: If you need help deciding which fit profile and size you should ride, visit a bike fitter to determine your ideal size. Seven does not make size recommendations remotely.
Bike geometry calculated with 700c x 43 mm knobby tires.
Top tube length is effective: Starting from the centerline of the head tube and top tube intersection measured horizontally to the ground, back to the seat tube.
Frame stack BB-HT: This is what most bike companies simply call "stack." However, there is frame stack and separately handlebar/stem stack. Seven clarifies frame stack by including BB-HT. Because we only provide frameset specifications (rather than bike specifications), we cannot provide stem stack here.
Frame reach warning: This popular measurement is not a good gauge of proper bike fit. Also, the term is not accurate and, therefore, often causes confusion. Seven qualifies the term with "BB-HT" to help define the measurement. Regardless of these shortcomings, we include frame reach BB-HT because it has become a popular industry shorthand for comparing one bike size to another. While the frame reach numbers Seven shows here are accurate, Seven does not take responsibility for an ill-fitting bike if a fitter relies on the frame reach number. Top tube length combined with stem length is much more relevant and helpful in bike-to-bike fit comparisons.
Fit Geometry footnotes continued:
Standover height is measured midway along the top tube, the actual typical point where a rider stands on a bike. Be aware that this is different from how many production bikes measure standover height.
Rider height range, typical: Choosing a bike size based on height is not wise. We include height ranges because it is a standard industry practice. If you need help deciding what size you should ride, visit a bike fitter to determine your ideal size. Seven does not offer size recommendations remotely. Including size ranges also highlights that most riders could choose from three Rider Ready sizes — as opposed to one for most stock bike alternatives.
Rider weight range: This is the rider in birthday suit, without any clothing, equipment, hydration, etc. To understand Seven's ride weight philosophy and parameters, read our Ride Carry-Weight standards. Ranges shown here are our recommendations for optimal ride performance. However, if your weight is above the recommendation, the bike will still handle and perform significantly better than any stock bike. For specific component weight limits, check with the manufacturer.
Frame Geometry Performance footnotes:
Toe overlap warning: Because toe overlap is determined, in large part, by factors not related to frame geometry, we cannot guarantee that your bike setup will not have any overlap. Make sure you are comfortable with the length of the front center before ordering a bike. You can check your current bike to compare front centers.
Seat tube length is measured from the center of the bottom bracket to the intersection of the top tube's centerline. To determine the total seat tube length from the top edge of the seat top to the center of the bottom bracket, add about 4.5 cm.
Tubeset Stiffness, Performance, & Handling
We offer this frameset in three performance configurations: Benchmark, RocketShip, and SuppleState.
Note: Constant Wall Titanium Tubing: Seven has more than 20 tube diameters and walls to engineer with. These options allow us to fine-tune the bike's ride and performance.
This is out most popular performance tubeset. Excellent choice in all situations.
Stiffness is the priority. Good for acceleration. Not for comfort.
A specialty tubeset. Comfort is the priority. Good for long rides. Not a competition bike —unless that event is 12 hours-plus.
Why choose this tubeset?
Ideal for about 80% of riders. Balanced. Most capable over the widest range of use. Excellent at everything. Seven's stiff drivetrain and high smoothness flow. When in doubt, choose our Benchmark tubeset. The best harmony of all possible features. Seven's most popular tubeset choice.
Our stiffest Rider-Ready frameset. Stiff in all directions: Drivetrain, torsion, and bump feel. If you're a larger rider or just love the way a stiff frame feels, choose our RocketShip tubeset design. Handling is slightly more agile and quick than average.
When a smooth ride is most important choose our SuppleState tubeset design. Good for long distance riding where comfort outweighs flat out acceleration. If you're looking for a more traditional titanium ride feel. Handling is a bit more stable and surefooted than average.
Considerations
None.
Not ideal for lighter riders, long distance riding, or if you're looking to improve comfort on the bike.
Not ideal for larger riders, single-digit-hour competition rides, or carrying more than 15 lb of gear.

Performance Profile Visualized
Why choose one tubeset over another? Each of the three has very distinct benefits.
Footnotes:
Seven's standard performance baseline is "100%": The performance that Seven's typical bike in this riding category provides. In general, 100% is excellent performance in most cases. When we specify a different percent, it means for this specific model with these specific features, options, and upgrades, we believe the change provides a benefit.
Sustained climbing: Long climbs, usually seated. A lighter, more lively frame can make long ascents quicker.
Punchy climbs are short ascents on which you're pushing big watts or standing for a good portion of the climb. A stiffer tubeset can benefit this kind of climb.
High-speed descending: These are long predictable descents where stability is important. If you want more confidence on long descents, you want more of this trait.
Technical & quick: Your movement on the bike affects the bike's handling, feel, and control. The more amenable your bike is to body English, the more control you have in tight situations: twisty switchbacks, tight corners, and tricky trails.
Weight Balance: Are you doing loaded pack riding? Are you doing minimalistic performance riding? Different cargo levels benefit from different tubeset designs.
Cargo capacity: If you're carrying more than about 14 lb (6 kg) you're starting to get into the cargo-carrying range. That benefits from a bike that leans toward cargo capacity. Stiffer seat stays mean better bike handling when loaded with gear — but a harsher ride when unloaded.
Comfort & flow: Flow encompasses all the positive aspects of a smoother ride and improved tire traction and control. You flow over rocks, roots, broken pavement. You can use body English more actively. Your tires maintain better contact with the ground. Flow is one of the most important and impactful aspects of a performance bike.
Frame Weight: The performance elements of the frame determine the frame's weight. Frame weight is an outcome of ideal bike design rather than an input requirement. A punchier climber will be stiffer. A frameset with more comfort and flow will be lighter. Your choice of ride characteristics determines the frame's weight.
Options & Upgrades
Dropout Type
Seven offers two dropout types for this model. The essential difference is the derailleur hanger:
Integrated derailleur hanger: This is available at no charge. This is the most common option. It is differentiated by having the toughest derailleur hanger on the market. It works with every derailleur type except SRAM electronic Transmission systems.
Universal Derailleur Hanger (UDH) This option is a $95 upcharge. It is universally compatible with every mainstream derailleur including SRAM's unique Transmission system. The weakness of the system is that the hanger is aluminum and will get destroyed repeatedly. It is replaceable but you must ride with spare parts.
This is a no charge option. Choose either Moto or Inline style stays.
Moto Seat Stays
These are our most popular seat stay design for gravel bikes. In our Rider-Ready series, Motos provide the smoothest ride possible without sacrificing drivetrain stiffness.
Moto seat stays are our most popular.
Inline Seat Stays
These are our classic s-bend stays that that are the standard by which other stays are judged. Choose Inline stays you want a more traditional aesthetic.
Inline seat stays provide a more subtle aesthetic.
Upgrades Available
Third bottle mount under down tube
Most bikes have one or two water bottle mounts. You can include a third bottle mount on your Seven if you'd like.
This is a no charge option.
Fender mounts
Our fender mounts include one on each dropout, a chainstay bridge mount, and a seat stay bridge mount that is oriented at 90 degrees to the hub. This is optimized for 99% of all performance fender systems.
This upgrade is $145.
Travel couplers for easy luggage packing
If you travel with your bike, or want to travel with your bike, more than once a year, it may be worth investing in our coupler upgrade. Read all the details and benefits.
This upgrade is $1,995.
Etched Graphics
The price for etched graphics is $250. Most of our graphic options are no charge. Etched graphics are time-consuming. But they look great.
We offer this frameset with any of our housing routing options. Read the detailed comparison of Seven's housing and cable routing options. Following is a summary of the benefits and considerations of the various cable routing systems.
Housing & Cable Routing Type
External Routing
InLine Internal Routing
IN-Route (Enve) Internal Routing
Universal Shifting Routing
Pricing
No upcharge
$495 upcharge
Why choose this routing?
Simple, lightweight, easy to maintain and service. When in doubt, go with external routing.
A good balance of the full internal aesthetics without much of the complexity of IN-Route internals.
Not available on mountain bikes.
Futureproofing. When you're unsure of what parts you might want to ride five years from now.
Considerations
Exposed and visible cable stops and housing zip tie guides.
Maintenance is required more often, is more expensive, and should be performed by a professional mechanic. Warning: Internal housing routing can cause injury or death if not properly installed and maintained.
This is a kitchen sink solution. It looks unusual. This option has ports (for internal routing) AND exposed and visible cable stops and housing zip tie guides (for classic routing).

The A-Frame head tube graphic in matte Slate Blue with Charcoal Outline. The colorways match the down tube graphics. Our A-Frames do not have metal head tube badges as some of our other models do. That's okay. Metal badges don't enhance the performance of your Seven; they just add cost.
Seven's USA and handbuilt graphics with world championship colors. Every Seven receives these graphics.
Skip machines the front end of a frame. He's been a framebuilder for more than 30 years. He knows how to build a frame right. you'll see.
Matt confirms that this frame is straight and true. Riding speed increases as frame straightness improves.
This 29er gravel bike is ready to ride. Unfortunately, it's in the way of our framebuilders.
"I was a little skeptical at the beginning of the whole process because I wondered if it was worth the money to purchase a bike like this. All I can say is it is a pure joy to ride this bike and I am so glad I got it"
— Dan H.
Why is Seven's Gravel 758 the ideal classic gravel bike?
Here are a few reasons:
Toughness: Titanium can handle abuse and impacts that would crack, rip, or dent other materials. Nearly impervious to wear damage from grit and grime — unlike carbon. Seven's titanium 3-2.5 alloy is the best material for building the toughest bikes.
Complete Trust In The Equipment. Titanium for its durability and simple care. Seven's material engineering for longevity.
Terrain Versatility: This gravel bike fits up to 700c x 58 mm knobby tires — for serious gravel — down to 43 mm slick tires — when allroads riding calls to you.
Better handling: Available in 12 sizes and 3 fit profiles, The 758's more precise sizing provides much better rider weight distribution and center of gravity for the best handling of any stock bike.
Unparalleled ride feel and fun for two reasons:
Each of The 758's 12 frame sizes has a size-specific tubeset with an optimal rider weight range. Rather than a single weight limit for all sizes — as performance carbon bikes seem to have — The 758's optimal weight recommendation provides a ride feel and rider connection that has never been possible with a stock bike.
We offer three distinct tubeset styles to meet your needs: Super stiff, our benchmark design, and a super smooth and resilient tubeset.
A new level of control: Again, 12 frame sizes in 3 fits with 12 distinct tubeset profiles and 3 tubeset types. Add to this Seven's innovative application of titanium, and you've got more intuitive body English control than ever.
Better fit because The 758 comes in 3 distinct fit profiles: Our Standard Fit, Endurance Fit, and Aero Fit. Seven's Standard Fit, in 12 sizes, provides a riding position similar to that of popular stock bikes. Our Endurance Fit, in 12 sizes, provides a slightly higher front and has a bit shorter reach. Our Aero Fit is lower and longer than our standard fit. That's 36 sizes to choose from — compared to 5 to 7 for stock bikes. We're confident you'll have a better fit than any stock bike you've ever ridden.
Why a gravel bike from Seven?
Too many reasons. Here are just a few:
Applied Experience: Seven gravel bikes have been ridden to multiple pro podiums at the Unbound 200. Sevens have been under winners of the TransAtlantic Way 2,500 km gravel race. Seven's gravel bikes have proven themselves in all conditions, from the brutal 200k Rift Iceland to long-term ultralight bikepacking, and everything in between. Seven has built more mission-specific titanium gravel bikes than anyone else. We bring this knowledge base to every new bike we build. Your Seven will have the same pedigree.
More Framebuilding Experience: Most Sevens are built by three artisans — a framebuilder, a welder, and a framewright. On average, these three have over 40 years of framebuilding experience. There are no more experienced titanium builders on the planet. This depth helps us build better bikes.
More Titanium Experience: Without a doubt, titanium is the best frame material for gravel bikes. Seven's founders have been building titanium bikes for 38, without interruption, and therefore, longer than anyone else. 30-plus years ago, Seven's founders developed the titanium tube specification that is still widely used today. If you want something built of titanium, there is no more knowledgeable team to work with.
Continuous Innovation: One of our founders was racing drop bar mountain bikes 38 ago. We thought we were onto something. (Maybe just a couple of decades early.) We've learned continuously since those early days. Fast forward to today: Our latest work on vibration damping and big hit control can be felt in each of these frames. Seven has always pushed the bounds of what's possible on a bike. This design has more of what's proven and none of what's not.
Built by riders for riders. Who built your bike? Many of our crew ride gravel bikes as their primary love. We've been riding the local trails for more than three decades, since before mountain bikes became a thing. Some of us cut out teeth in BMX, some in cyclocross, and some just rode into the woods. Whatever the reason to ride, it's all good. And even better in the dirt.
Made in the USA. Our founding team has been building bikes in Massachusetts for more than three-and-a-half decades. There are a lot of reasons we build bikes this way. In the end, all that really matters is whether you can feel the difference in the ride. We find that most riders do.
