Seven now offers the BB30 oversized bottom bracket option. This new international standard is available as an option on all of Seven’s current titanium and steel frame models.

What is BB30?

BB30 is the term for a new open standard of oversized bottom bracket shell that uses a 30mm spindle and direct-fit, pressed-in bearings.

Why would someone consider BB30?

The design eliminates the use of external cups that are threaded into the BB shell to hold the bearings, reducing both overall bike weight and the q-factor of the pedals. The larger bottom bracket shell also accommodates a 30mm spindle, instead of the more common 24mm spindle. This translates into increased drivetrain stiffness.

Is the BB30 68mm option compatible with my current 68mm English threaded bottom bracket?

No, this new standard requires the use of a completely different bottom bracket from our standard offering, so there are no parts that are compatible with both standards.

How much does the BB30 68mm option cost?

The additional charge for this option is $295.

Seven now offers a greaseless belt drive system as an alternative option for Singlespeed bikes.

What is the Carbon Drive™ System

The Carbon Drive™ System uses a carbon reinforced polyurethane belt in place of a metal chain. The single piece belt has the necessary tensile strength and high modulus to provide a smooth, clean, and long lasting ride experience. This type of system can be used on either road or mountain bikes.

Why Choose the Belt Drive option?

• Race tested Technology has been in use with motorcycles for 25 years
• Clean, quiet, smooth running action Sprocket design sheds mud, snow, and other debris
• Maintenance free No lubrication required; just get on and ride
• Durability Lifespan of a Carbon Drive belt is longer than a conventional chain
• Light weight Carbon Drive Belt and sprockets weigh less than traditional set-up

How much does the Belt Drive Option cost?

The price of this option is $225.

This includes only the bolt-on junction at the dropout and seat stay. This option must be used with a track dropout, an eccentric bottom bracket, or slider dropout to correctly tension the belt. Carbon Drive™ belt and components are not included in the price.

New Seamless Design Blends Aesthetics with Rigidity and Reduces Weight

Seven’s Integrated Seat Post is a new option designed to eliminate the need for a conventional seat post. Since 2006 we have offered the Diamas with an integrated seat post. We now offer a titanium and carbon ISP option on the Elium SLX, Elium SL, Mudhoney SLX, IMX SL and IMX 29 SL for a total of two road models, one cyclocross model, and two mountain bike models.

Lighter

Because there is no need for excess seat post tube to be inserted into the frame, the ISP option is lighter weight than our frame and carbon post separately.

Stiffer

By using a titanium and carbon extension of the seat tube, we create a larger diameter post section that improves stiffness and lends a greater sense of connectedness to the ride feel of the bike.

Seamless Lines

With no seatpost junction to interrupt the lines of the bike, the ISP delivers a sleek aesthetic that was not available until now.

Versatility

Custom designed with your frame to match your saddle height, minor adjustments are simple. At a given ISP length, the saddle height can be lowered 2 cm and raised 2 cm. With 2.2 cm of setback, the ISP can be used for road, mountain, cyclocross or triathlon disciplines. The ISP uses the same custom designed saddle clamp available in Seven’s new titanium seat post.

New Option Available at No Charge

Seven now offers the perfect option for riders that plan to use disc brakes with their new bike, but also want to incorporate racks and panniers.

Our new design positions the disc brake inside the frame, which allows you to select almost any type of rear rack. Riders now have more equipment choices and fewer compatibility issues. Whether your bike is designed for commuting, touring, or off-road expeditions, the Low Mount Disc Tab offers versatility and convenience at no additional cost.

This option is available on any Seven model that accepts disc brakes.
