Bastion #43

Stealth Elegance


This is a truly special build and even with the front end you can see some of the special details used for the client. We used a special 'riser' bar in this build. With an overall rise of 3.5cm from the top of the saddle to the bars, and with a relatively tall 82cm saddle height, we were concerned that getting all of that rise from the headtube was not going to translate well on the road. We would either have had to have a 20+ degree top tube or almost no exposed seatpost, which would result in a very harsh ride. The client preferred the bars to an extremely sloped top tube, and has loved them out on the road. Note the chrome paint on the Enve stem that matches the color of the new Dura Ace 9100 series components. 2.jpg#asset:683

For those with sharp eyes you might notice a lack of Junction-A box on the stem. We used Shimano's new handlebar end junction. The bars are taped with Fizik 2mm Superlight Soft Feel Tape, a shop favorite. It provides excellent grip in wet and dry conditions with or without gloves and is for those who prefer a more direct feel.13.jpg#asset:684

Another view of the bars from behind where the rise is more visible. The client loves to climb, so while some might prefer to keep the tops unwrapped, this was his preference. It is something we find in many cases to be more pragmatic for everyday use. You might even find more pro-tour riders with fully wrapped 'aero' bars than you might expect!15.jpg#asset:685

We chose to have a wrap go over the ends of the tape to seal it out from the elements. While some prefer a clean line (and we often do) this again was a pragmatic concern.  Also note the black screws vs. the stock silver ones for a cleaner look. 16.jpg#asset:686

Zipp's revolutionary 454 wheels are not just marketing type. Having tested them we can truly say they offer an advantage. They are fast, yet stable in crosswinds. Note the chrome paint inside the fork and on the bottom on the outside. While the wheels come with a nice Zipp stem extender, the client preferred full length valves so we wrapped them in tape to keep from rattling. Also note the heat shrink around the Di2 and brake line to keep the front end as tidy as possible.4.jpg#asset:690

If you zoom in you can see the custom Bastion 12mm thru axle and Sapin CX Ray spokes laced to Zipp's Cognition hub. 5.jpg#asset:691

The upper rear lug has Bastion's Logo, super trick. For now they are offered as ISP only, as the ride quality is improved over a slide in seatpost. Given that each bike is custom made, there is no concerns about having to change it for other riders.8.jpg#asset:688

Looking the other way. Although not used on every build, the SMP T5 has been great for a handful of clients. That being said, we have probably sold no less than a few dozen different road saddles to our clients in the past year. As what works for someone else is not an indicator of what can work for you. Also note the very trick ISP Topper with Bastion's logo.3.jpg#asset:689

Despite its overuse, the word 'beefy' is more than justifed to describe the bottom bracket lug on a Bastion.  As breathtaking as this view is, what is inside is just as impressive. By utilizing 3D printing the inside of the lug has a honeycomb design allowing it to be much lighter and stiffer than a traditional Ti lug. 


On the flip side it is just as cool.  While normally we wouldn't embrace clashing carbon fiber finishes, it just plain works on this bike.  Note the new Dura Ace 9100 pedals. Although not groundbreaking in their update, the slight tweaks are classic Shimano - improving the best a little bit in each iteration.


The rear end is just as clean.  The Dura Ace flatmount caliper has finned pads to assist in dissipating heat. The rotors themselves are a metal sandwich, steel on the outside with aluminum on the inside to preserve braking feel and rotor durability while still having great heat dissipation. Even on the longest descents with a heavy rider, these brakes are just as good the first foot of stopping as they are miles down the road after heavy use.  Also note the frame number in the lug. 


Right after shooting this bike the owner ripped up Gilbratlar road in Santa Barbara with a massive smile on his face (or at least he had one when he sent a photo from the top).  This was the first of many trips for the one of a kind build.
