Gravel Tire & Gearing Ranges

Seven’s Rider-Ready gravel bikes cover all the dirt-centric bases, with 14 models.  That number is just for frame types; it doesn’t include parts kits, cockpits, or wheelset options.

Fortunately, deciding which is right for you is simple.

Generally, riders define gravel bikes by a few attributes:

  1. Maximum tire size, minimum tire size
  2. Gearing and range
  3. Frame and fork mounts, cargo capability
  4. Frameset geometry, handling
  5. Tubeset, ride characteristics

The two most commonly researched attributes are tire size (how big can the bike go?) and gearing (does the bike have the right range for how I ride?).

Seven Rider-Ready bikes have a greater maximum tire size selection than any stock bike brand.  We also offer the most gear range options of any brand.  For example, our Gravel 743 model has 15 kits to choose from, 19 wheelset options, and other options and upgrades.  You’ll find the perfect parts combination for your riding.

Here’s Seven’s current gravel Rider-Ready bike lineup by tire size range and gearing range.  We’ve also included wheel axle widths, an unusual focus for gravel bikes, but it’s becoming useful because of the recent interest in larger tires.  Our Gravel 761 and 761s (Slang geometry) are designed with boost axle spacing for a stronger, stouter wheel that can handle rougher terrain.  The 761 and 761s are true mountain bikes with drop bars.

We offer six maximum tire sizes across our 14 gravel Rider-Ready models.

Why so many tire sizes?

As the rear tire gets larger, the chainstays must get longer, and optimal gearing tends to get lower.

The more specifically we can offer your ideal maximum tire width and gearing, the shorter we can make the chainstays.

Chainstay Lengths

No one wants chainstays longer than necessary. [1]  There’s no reason to have longer stays if you don’t want a larger tire.  Choose your max tire from our six offerings, along with your preferred gearing, and you’ll have a bike with optimal handling geometry.

Max-Min Tire Width Range

Equally important, when the maximum tire size changes, so too does the minimum tire size.  Most bike specs are silent regarding recommended minimum tire width.

We find that for many riders, the min-max range is as important as the maximum tire size.  Many riders are dual-wheel riding these days – having a wheelset for gravel riding and a second wheelset for road riding.  So, knowing the recommended minimum tire size may influence your purchase decision.

Having a balance of tire size range is often the ideal.  For example, the Gravel 747 is currently Seven’s most popular bike for tire range.  The 747 is an excellent 30 mm tire road bike, and at the wide tire end of the spectrum, the 47 mm tire is nearly a mountain bike tire.  It’s a combination that’s difficult to beat.

Gearing

In another example, our popular Gravel 758 gets you to 29 x 2.3″ tires (700 x 58 mm).  On paper, the 758 is similar to the Gravel 761.  However, there are two important differences:  1)  Hub spacing and 2) gearing.  These might seem like minor distinctions, but for some riders, it’s the difference between perfection and just another gravel bike that missed the mark.

The 761 is a true mountain bike with drop bars (and frameset geometry designed for drops).  The 758 is capable of the same trails but is also designed for gravel gearing and has gravel hub spacing.  This gravel axle spacing provides more wheel options, but they are not as tough and stiff as mountain bike wheels.  Of course, everything is relative.  Our 758 is tougher than any other gravel bike on the market.  It’ll hold up; don’t worry.

Each of our gravel models, including our current special edition 747 and our MantaRay 743, has specific purposes.  One of which will be ideal for you.

Life is short.  Choose your own adventure, bike, and ride.


Footnotes:

  1. Longer chainstays are not a bad thing.  Riders tend to focus on short chainstays.  The shorter, the better, right?  In reality, after designing 35,000 bikes and doing endless testing, Seven knows that shorter stays are almost never the answer to improved handling.  Regardless, if you want the shortest stays possible, Seven offers our chopped chainstay design that provides among the shortest chainstays possible for any tire size.

Evolving Gravel Bike Tire Sizes

Gravel bike tire sizes are getting wider, fast.  We see a lot of interest in 50+ mm tires.  Some riders say bigger tires are faster.  Some say it’s bunk.  It partly depends on the terrain you ride.  The rougher the terrain, the faster a wider tire will typically roll.  It also partly depends on the harshness of your ride; a wider tire will help mask the shortcomings of your frame and fork.

The chart below shows 10 of the most popular and respected gravel bikes compared with Seven’s Rider-Ready gravel bikes.  Our three gravel designs (plus our allroads) cover every kind of performance offroad riding.

Seven’s Gravel 758 is designed for 2.3″ (58 mm) mountain bike tires.  This machine is a proper mountain bike with drop bars.  Ideal for rough trails and rocky terrain.

Seven’s Gravel 753 has room for 53 mm (2.1″) mountain ready tires.  The 753 is our riders’ current most popular balance of capability and speed.

Seven’s Gravel 743 is our classic gravel bike.  It’s what most people think of when they think gravel.

Seven’s Allroads 738 is as capable as some popular gravel bikes.

Seven’s Rider-Ready gravel bikes are not warmed over mountain bikes.

Control or Fatigue?

Interest in wider tires has a lot to do with harsh riding frames of carbon or aluminum compared to well-designed titanium.

Do you want wider to help smooth out the ride and take the edge off, or do you want wider to give you more control at higher speeds and in more demanding conditions?  If it’s the former, a Seven titanium frame is a great answer; this will provide you all the shock absorption you could want without the need for a wider tire.  If it’s the latter, Seven offers more wide tire options and sizes than any other bike brand.

Whatever gravel you want to ride, Seven’s got it covered.

Holden Hudson from Bike Doctor Arnold

Holden from Bike Doctor Arnold had his first ride on his new Axiom SL at the Hincapie Grand Fondo in Lehigh Valley over the weekend. He felt super comfortable and was able to tackle 53 miles of punchy climbs and gravel descents. These are the before and after photos of Holden with his bike. He says it’s exactly what he wanted and he felt right at home on it immediately.

If you’re in the Arnold, Maryland area, contact Holden if you’re interested in hearing more about having this kind of experience for yourself!
