What Comes Around

The circle is a powerful symbol and a strong shape. Our friends at Circles Japan commissioned this paint scheme, dubbed, aptly enough, “the circle,” for a run of road and cyclocross bikes we did with them. Shinya Tanaka, Circles’ owner and big-thinker, loves the idea of iterative learning and improvement, of putting back into his cycling community all the good things he takes out. We iterated this scheme in five different colourways for him.

There are a lot of great pictures of these bikes here. It is good to work with people you can call friends, people who can teach you about their cycling culture and reinforce what we all, as bike lovers, have in common. Watch this space for more collaborations with Circles and others in our extended circle of friends.

On the Road: Evergreening Sedona – The Bike in Detail

Bike riding is fun, and exploring the world by bike is another order of fun, however…when you’re taking on desert terrain, bike packing, being prepared is a serious business. For our week in and around Sedona, we outfitted our Evergreen SLs with a slew of specialized componentry and accessories. The double-butted Ti frames themselves are ideal for this kind of trip, super-durable but also comfortably compliant, so they serve as the perfect platform for this kind of trip.

1. S&S Couplers – The frame’s S&S couplers allow it to be broken down and packed into a travel case that does not incur additional baggage handling fees from the major commercial airlines.

2. Mechanical disc brakes – The mechanical (i.e. cable actuated) disc brakes can incorporate cable splitters, which make packing and re-assembly easier.

3 . Prototype light mount at fork race w/ Schmidt Edelux II generator headlight.

4. Light and Motion Gobe bar mount lights (x2) – More light = better. And they’re 100% waterproof.

5. Third water bottle – More water = better…especially in the desert.

6. Porcelain Rocket saddle bag – Expanding saddle storage for tools and parts. You never know what you’ll need, except that sometimes you do.

7. Drivetrain – 44/26 front chainrings coupled to 12/32 rear cassette for long days climbing technical terrain.

8. Son 28 generator disc hub – For battery-free lighting.

9. Clement MSO X’Plor 40mm tires – Big for comfort and traction.

10. Camera, Garmin 1000 & Garmin 810 – Hands free movies and pictures, plus navigation, plus back up navigation.

11. Prototype rear compression rack w/ compression bags – This versatile rack is collapsible for easy packing, and features a Ti “web” ideal for strapping bags and other equipment to. Not yet available for purchase, this is the first iteration in what we foresee being a long design cycle. Sea to Summit Compression Bag (x2) – Adaptable storage for all your desert exploration needs.

12. Ortlieb handlebar bag – Food and other necessaries, at your fingertips.

An Inspiring Evening

We are excited to invite you to a special event at 7:00 this Friday evening, August 22nd, at the Ride Studio Cafe in Lexington, MA. Headlining the night is Patrick Brady, renowned blogger and founder of Red Kite Prayer, author, cyclist, and our long time friend, who will be on hand to read from his new book, “Why We Ride.” If you have ever wondered the same, you’ll find yourself engulfed in this book in no time. The only thing preventing you from turning the pages is the overwhelming inspiration to get out and ride.

There will be plenty of time to mingle and share stories of your own, so please join us!

Patrick has also been busy collaborating with us on a travel bike, in fact a new series of bikes designed from the ground up to make transport as easy as possible. He travels around the globe, and the added expense of bringing a full-sized bike on a plane adds up. Together, we set out to develop the ultimate travel bike. Four of these bikes will debut at the event as well, including Patrick’s very own, a bike he’ll be riding for the Franklin Land Trust’s Deerfield Dirt Road Randonee (D2R2) this Saturday.

We’d love to see you, and introduce you to our good friend. Food, drinks, and story telling will all be provided. Additional details can be seen here: https://www.facebook.com/events/278740662331944/

Travel Specific Frame Details

We’ve written a little about the design mission behind Patrick Brady’s ultimate travel bike, to recap and over simplify, it’s going to be a coupled bike that is capable of tackling road rides, off-road adventures, and rides that haven’t been dreamt up yet. This will be Patrick’s dedicated travel bike, so it has to be adaptable to whatever surfaces he rides on and still fit into an S&S case.

Packing a bike in a box, 26″ x 26″ x 10″, is an interesting project. Bikes are oddly shaped machines, and are far better off being pedaled to where they are going than being shipped. Adding S&S couplers to the bike is a huge help when packing, but more can be done, and that is exactly what Patrick and our design team focused on, once his fit was complete.

The plan was to design a frame that would take up as little room in the S&S case as possible without sacrificing the bike’s performance, then build the bike with components that were easy on, easy off. Starting with the frame, we made the following design choices:

Top tube slope: A smaller frame, in general, fits in a case more easily than a large one. To make Patrick’s frame as compact as possible, we sloped the top tube ten degrees. This aggressive slope will leave more space in the case for other essentials without compromising performance or the number of water bottles he can use.
Cable stops at Head Tube: Handlebars can be one of the trickiest pieces of the bike to pack. They are oddly shaped no matter how you position them, and the cables and housing sprouting off in all directions only adds to the struggle. Having a handlebar that isn’t attached to the frame, rear brake, or the derailleurs is a real advantage when packing a bike. By using slotted cable stops in lieu of barrel adjusters, and a set of DaVinci cable splitters, the handlebar can be freed from the bike with relative ease. While we would normally recommend barrel adjusters for on the fly derailleur adjustment, in this case they don’t allow for an easy way to detach the cables from the frame. Slotted cable stops eliminate this problem, and in-line cable adjusters will take care of any derailleur tweaks, so that is how we will outfit Patrick’s bike.
Cable stops, not barrel adjusters at the head tube.
Disc mount: Most Seven road bikes that are equipped with disc brakes and also don’t have rack or fender mounts, have the rear brake caliper mounted on the back of the seat stay, above the drop out. The logic behind this location is that the brake is perched on the outside of the frame making it easy to work on when needed, and allows for a traditional cable routing path, along the top tube and down the seat stay. In a cramped case, where every inch counts, we think the “low mount” disc brake location makes the most sense. Welded on top of the chain stay, the low mount positions the brake caliper within the frame’s rear triangle, not only protecting it from getting dinged in travel, but also freeing up more space in the case.

Cable stops for Disc Brakes: When riders choose to run disc brakes, they often choose zip tie guides as the means to affix the housing to the frame. This set up allows for both mechanical and hydraulic brakes to be used, and leaves the option open to use either throughout the lifetime of the bike. We felt the serviceability of mechanical disc brakes made the most sense for Patrick’s travel bike today, and for many years to come. Once we came upon that decision, we could then make the switch to slotted cable stops, again adding to serviceability, and ease of assembly.

Once we begin building the bike, we’ll discuss some of the ideas behind Patrick’s component selection.

Dems Da Brakes

One topic that came up early in our discussions with Patrick Brady about the ultimate travel bike was brake type. Due to the wide range of tires he’ll be using, and the desire to keep packing and unpacking as simple as possible, Patrick felt cantilevers, or possibly mini-v’s made the most sense. Easy to set up and adjust, these brakes don’t require any additional tools or time to pack in a case. Patrick had ruled out cable actuated disc brakes for two reasons, first because disc rotors present a hurdle in the speed of packing the bike, each rotor has to be removed in order to fit, and second because Patrick had yet to find a cable actuated disc brake that he felt was so significantly better than a rim brake, that they’d be worth the hassle.

Before we knew how he felt about brakes though, we took him for a ride. His test bike was a coupled Evergreen SL, a sort of travel bike prototype outfitted with Shimano’s R517 non-series, cable-actuated disc brakes with 160mm rotors. The route (that he would crush us on) was what we call the Battle Path loop because much of the route follows the path taken by the British on their march from Boston to Concord way back in 1775. Other than an occasional street crossing, nearly the entire ride was off road. From single track in the Belmont Woods, to the long, swooping, packed dirt trails in Lexington and Concord, we rode through the unrelenting humidity.

Patrick basically rode one handed, using his free hand to snap pictures throughout, so it would appear that his opinions on braking power are believable. The ride was as fun as it gets, the trail conditions were top notch, and the scenery unbeatable. We love that ride, and Patrick’s smile suggested he did too.

Something changed for him during that ride. For the first time, he had a clear cut example, in his eyes, of a cable-actuated disc brake that performed better than a rim brake. This was an important discovery because many of the rides Patrick has planned for the travel bike are exceptionally rugged and will require a comparably exceptional braking platform. This isn’t to say cantilevers and mini-v’s couldn’t perform well enough, but he felt the disc was a needed improvement, so much so, that it became a requirement for his travel bike.

Back in the show room, we discussed the pros and cons of each brake type, cantilever, linear pull, medium reach, etc. There are clear advantages and disadvantages to each style, but for the type of riding that Patrick will use this bike for, especially the challenging off road rides, his choice was clear.

Disc it would be.

The question then became, what can we do to speed up the break down time when packing the bike? Discs come in two mounting styles, six-bolt or center-mount. We agreed that a center mount, though it requires a cassette tool to install, would save enough time to make it the clear favorite.
