Bastion’s choice of using titanium lugs instead of carbon is key to improved compliance rather than maximized stiffness. The reduced vibrations had us feeling fresher longer without the aches we experienced from the last lugged bike we tested, the Colnago C64 ( RBA, May 2019). The titanium lugs and carbon tube combo effectively damps road chatter and creates a stable ride that a complete carbon frame would miss or a titanium frame would feel flat. Even though we were using inner tubes and 25mm Continental Grand Prix 4000 tires, the Bastion had a ride quality that was more reminiscent of the compliance often associated with tubeless. Long all-day road rides are where the compliance of the Bastion performs the best. We spent well over a thousand miles on the Road Disc. Campy’s hydraulic disc brakes maintain the stopping power and modulation that continue to make them our favorite. The 3D-printed lugs gave the Bastion a most unique appearance.Ī pair of 35mm-deep Campagnolo Bora One carbon clinchers with 18 front and 21 rear stainless steel spokes kept us rolling. In this age of internal batteries, the external junction box and shift motor are a bit outdated and slower than the latest SRAM AXS eTap and Shimano Di2 offerings, but the emergence of 12-speed EPS should keep the brand in contention. The 52×36 chainrings coupled with the 11-29 rear cluster kept the gear jumps tight until the very top of the cassette. Although released eight years ago, the EPS system grabs the gears slower than the competition but still maintains Campy’s popular ergonomic characteristics in the hoods and levers.
BASTION BIKES PLUS
The clean, glossy tubes are complemented by the internal cabling and flat-mount disc brakes, plus a custom inscription can be added to the rear-stay lugs to bring added personalization.Īn 11-speed Campagnolo Super Record EPS drivetrain took us through the gears. Bastion also makes available seat toppers in different lengths to accommodate different Of note is the seat tube that pierces the seat lug and doubles as the seat mast with a titanium topper. Bastion’s 3D print technology cancels out the need for welds, as the lugs are printed to secure the carbon tubing once bonded. When we first laid eyes on the lugged frame, we assumed the combination of titanium and carbon had the makings of a compliant ride. Bastion’s customized seat topper is another example of the brand’s attention to detail. A Stiff frame uses an intermediate modulus carbon with thicker walls in the downtube and seat tube, while the Extra Stiff uses it on the top tube as well. Owing to its use of standard modulus carbon tubing, it’s also intended to be the most compliant as well. Our test bike was a Regular frame, and with a claimed weight of 1074 grams, it qualifies as the lightest of the trio. Each can be built to one of three specified performance characteristics: Regular, Stiff and Extra Stiff. Now offering three custom frame designs-Road, Road Disc, Cross Disc-with three different carbon layups available that affect performance and handling, Bastion is proving that custom frame building can be a fruitfulīastion makes a vast array of customization available with their frames.
BASTION BIKES ISO
By combining the first 3D-printed titanium lugs to meet the ISO standard for a frame, with carbon from a local Australian distributor and rear stays that they manufactured themselves, the resulting frame was an eye-catching carbon bike of breathtaking beauty and design. With a market already deluged with carbon frames, the trio were determined to do something different. However, when Ben Schultz, James Woolcock and Dean McGeary found themselves on the dole after Toyota closed the Melbourne, Australia, office they worked at in 2014, the three engineers banded together to make their shared passion for cycling work for them, thus the Bastion frame was born. For most of us, designing and building a bicycle frame and starting a new bike brand is not the sort of occupation we fall back on later in life.
