CNC Machined Components

From the headtube to the dropouts, nearly every part of your Engin Bicycle is machined in-house to exceptionally exacting standards. Freed from the constraints of picking from a parts catalog, we have developed an array of unique frame parts to suit the specific needs of your Engin.

Chainstay Yoke

Maximum tire clearance, minimum chainstay length, no compromises. We invested heavily in the capability to make our yokes, knowing the payoff would be huge: we can offer best-in-class tire clearance while maintaining short chainstays and plenty of chainring clearance. While others resort to flawed solutions that result in wider q-factors and hub compatibility issues, our yoke has only positive effects — its two-piece clamshell construction is stiff and lightweight, and serves as the cornerstone to the planted feel and stiff pedaling platform of our frames.

Dropouts

Dropouts to keep up with every new standard, made to the highest standard. Fitted with custom thru axles and titanium hardware, our dropouts are light and strong and set the tone of our purpose-driven aesthetic. Functionality is at the forefront, as they allow us to integrate features like rack and fender mounts, clean brake caliper fitment, and precision derailleur placement to match the setup of every bike we build.

Head Tubes and Bottom Brackets

Machined in-house, our head tubes and bottom brackets complete the package as two fundamentally important axes of the bicycle. Engraved head badges add to the timeless look of our bikes and are guaranteed to last the lifetime of your frame. Our bottom brackets use a precision threaded interface in the T47 standard we were instrumental in pioneering, offering silent and reliable performance with quality bottom bracket options available to match every major crank manufacturer’s spindle standards.

Masterful Construction

Building with titanium is undoubtedly harder, but it offers a combination of qualities other frame materials can’t match. Extreme durability and resistance to corrosion complement a unique balance of ride quality and light weight, making it ideal for custom made frames. The challenges of working with titanium create a high barrier to entry; welding requires levels of cleanliness more typically found in laboratories and operating rooms, and a complicated system of distributing gasses at the weld site and through the frame tubes during assembly. It also calls for an expert touch during the two-step weld process to achieve a clean look and strong joint. But these are only the finishing touches — thoughtful design, rigorously cut miters, and custom fixturing lay the foundation for durably made frames that hold up to years of hard use. At Engin, our dedication to process makes us uniquely suited to the task of building top-tier titanium frames.

Custom Finishing

The process of making an Engin isn’t finished once the welds are cleaned. There’s a number of great ways to set off the look of your bike, and we’re able to offer a full range of finishing options to suit your style. We can do subtly etched logos that highlight titanium’s natural beauty and resilience. We can anodize frames in-house to take advantage of the unique ways in which adding nanometer-thick layers of oxidation to your frame can tease out a spectrum of stunning, vibrant colors. We can give your frame a classic look with custom designs to be applied with wet paint or cerakote. We can even combine these processes to create a truly singular aesthetic for your Engin. The choice is yours.

Complete Assembly

Finally, we assemble your bike with a selection of components chosen to meet the specific needs of your riding experience. This process actually starts at the inception of your frame; how you plan to use your Engin will dictate our parts selection and thereby impact the design parameters of the frame. By keeping the final build of your Engin in mind, we can eliminate the possibility of unforeseen compatibility or fitment issues, and ensure the end result is a bicycle that functions as a harmonious whole. Decades of experience running a full service bike shop has kept us continually informed on the ever-widening array of what component manufacturers have on offer, so you can rest assured nothing will compromise the final outcome of your Engin build.

Progressive Geometry

There’s a reason bikes today are better than bikes from 15 years ago, and it’s not just the materials or components. As riders explore the horizons of what’s possible on a bicycle, we’ve had to evolve the geometries of our bikes to keep up. A well constructed bike with top-of-the-line parts can deliver an underwhelming ride experience if it fails to take the proper form. It’s why we keep a keen eye on these trends at Engin, and continue to take part in the process of defining the shape of the modern bicycle. Much has been made of the geometry revolution that has swept the mountain biking world by storm, but we certainly don’t stop there. Our gravel bikes, for instance, also benefit from the increased stability and capability of a slacker head angle in concert with a long front center and steep seat angle, all while maintaining a lively character on the tarmac. In short, know your Engin will be ahead of the curve, not behind it.
