We recently made 30.9mm titanium seat posts available for order.The first production post went to a customer in Belgium who is 6’8″. Doing these larger diameter posts requires that we make a thinnersleeve for the seat tube. Every Seven seat tube gets asleeve, either carbon or ultra-thin aluminum,to keep the keep the post from binding, except, of course, for the integrated seat posts (ISPs) we do for our carbon SLX bikes.

The 30.9mm standard, and indeed the 31.8mm standard, represents a leap forward in the stiffness that can be built into a customer’s bicycle. While we are making 30.9mm posts available for sale, it is important to note that these will only really benefit larger riders.Part of the charm of titanium is that it retains a suppleness that makes it comfortable to ride all day. Over-stiffening eliminates many of the benefits of building in Ti in the first place.

We willalsobe producing a titanium seat post at the 31.8 standard, though not for use with Seven frames, and again, we would only recommend these for larger riders as they are the stiffest, heaviest posts we make.

As with many of the additions we make to our product line, the 30.9mm seat post is a result of customer requests. Larger riders want the benefits of riding a custom, Ti bike, but they are concerned that standard tubing, even with thicker tube walls, won’t produce the long-lasting ride feel they’re looking for. We hope that offering this new, wider post will help them find exactly what they’re looking for.

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.
