Component design is about refinement. Take a basic element of the bike and focus on each little detail to make it as good as possible. After seven years of steady progress, we now offer a full complement of custom, proprietary titanium components. Each component represents countless hours of collaborative design work between us and brilliant designers across the country, and even countless-er hours of expert machining and construction. See something you like? Grab it in our store anytime.

For such a simple component, it is remarkable how much opportunity seatposts present for smart design.

We selected the ideal wall thickness for TIG-welded titanium seatposts to make them strong and to help dull bumps in the road. An elegant curve for setback posts matches the elegance of the brushed or bead blasted titanium finish. And now we make our posts with a custom designed and CNC-machined top to fit Enve’s brilliantly simple and secure 2-bolt seat rail clamp, making ours the only ti seatpost compatible with that design.

  • 27.2mm diameter
  • Custom offsets from 0-25mm
  • Works with 7mm and 10mm saddle rails
  • Brushed or bead blasted with contrasting Firefly logo
  • 300mm post weighs 184 grams

Look closely at our stem design and you’ll see a theme. Titanium is precisely carved away around the steerer tube clamp bolts and face-plate bolts to minimize weight and maximize style (we measured it) without any reduction in strength.

We worked with Josh Ogle, a watchmaker by trade, to refine this design to the greatest degree. We then build our stems in custom lengths and angles to pinpoint your riding position exactly as you need it, and custom finishes to make them look exactly as you want.

  • 28.6mm steerer clamp, 31.8mm stem clamp
  • Custom lengths from 70-150mm, custom angles from 0 to + or -17 degrees
  • Brushed or bead blasted with contrasting Firefly logos
  • Available with a size matched, custom-machined, 5mm Firefly headset top cap
  • 110mm stem weighs 140 grams
  • Recommended torque for all bolts: 5.5Nm (check with fork and bar manufacturer for exceptions)

Custom made in California by Josh Ogle of Ogle Watch Company, our 6/4 titanium seat collars feature a unique dual-barrel design to keep the bolt perfectly aligned as it is tightened, placing the least possible stress on the bolt and the collar.

The carefully designed and precisely machined shape distributes the clamping load on the frame while reducing the weight to a feathery 25 grams. The collars arrive to us in remarkable condition, meaning it takes only the lightest touch from us to bring them to a flawless brushed, bead blasted, or anodized finish.

  • Available in 35mm (1.375″) & 31.8mm (1.25″) inside diameters
  • 4mm allen key bolt
  • Recommended torque: 4Nm (6Nm max)

JK. But these spacers do look great, perfectly matching the 31.8mm outside diameter of our stems for a seamless look and featuring subtle hints of vivid anodized colors. And staying true to our custom fit philosophy, we offer a more complete range of sizes than you can get anywhere else, including four 1mm micro-adjust™ spacers, to provide the maximum ability for adjustment. Fit-fidgeters, rejoice.

  • Kit includes 1x10mm, 2x5mm, 1×2.5mm, and 4x1mm spacers
  • Plain spacers are brushed ti, but can be bead blasted upon request

We’ll let Silca speak to the unmatched quality of their pumps below. All we can do is make them look even better, with custom butted pump bodies and flawless titanium finishes.

“Impero Ultimate features a high tech head gasket with unique 2-stage seal to provide ultimate sealing and holding even when compared to lever chuck designs. Solid aluminum head with brass check valve ensures a lifetime of flawless use, and fully handle and piston rod result in a pump that is both competitive in weight with plastic designs while being significantly stronger, smoother and more durable.

Unique FlexWing Silicone bumpers on the head and handle tip are designed to handle tubing diameters from 1″ (25mm) to 2.5″ (64mm) using a unique flexible outer wing which adjusts under pressure. An additional Silicone bumper on the main barrel protects paint, eliminates vibrations and noise, and also acts as a compression lock against the pump handle to keep it from moving unless you want it to.”

Available in S, M, L, XL, XXL, and XXXL sizes (see chart for detail)
