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) 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.
For exhaustive details visit our dropout page.
Seat Stay Design
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.

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.

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.
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.

Etched, Unified Design
Housing & Cable Routing Options
We offer external cable routing for our fat bikes. We don't offer internal routing of any kind because it's not well suited to the self-sufficiency and durability that fat bike adventure riding benefits from.
