Gallus Cycles

The brand was founded by Jeremy Shlachter in 2009. It is currently located in Denver, Colorado, United States.

“While costing more than some foreign assembled frames, we believe the quality, fit and one-of-a-kind nature of our frames more than offset any added expense. Every effort is made to source materials domestically, thereby minimizing environmental impact and promoting U.S. products, in contrast to foreign frames and bicycles transported from half a world away.” –Jeremy Shlachter

Gallus track bike
Gallus track bike. All frames are custom, so every detail can be tailored to your needs. To make the choice easier, track frames are usually built around a traditional geometry or as an urban fixed gear. Both frame styles have a high bottom bracket for pedaling through corners. Traditional track frames tend to have a steeper head tube and seat tube angles, short chain stays and fork length. This creates a stiff speed machine, perfect for the track or those double express cross-town deliveries. The urban fixed gear has a slightly slacker head tube, longer stays and fork. It’s still plenty fast, but would ride more like a road bike than a track frame. That said, the very nature of being a custom frame builder, enables us to apply the simple elegance of a track/fixed/single speed to the geometry that suits you, your style, and desired comfort.

Gaulzetti road bike
Gaulzetti road bike. “The design elements of each Gaulzetti are based upon traditional Italian racing geometry with regard to fit and function, but updated for the rigors of modern racing conditions as well as for the ergonomic demands of contemporary components. Gaulzetti Cicli produces a nimble, fast and balanced bicycle. The frames are designed to excel under all potential race conditions, especially technical courses where constant hard cornering and rapid changes in tempo are encountered. Years of experience on the Belgian Kermesse circuit and a history of training and racing on the poor roads of northern Europe and New England influence each detail. The Gaulzetti Cicli geometry may not be ideal for every cyclist, but an athlete seeking a pure race bike need look no further for the ideal bicycle. Sizes highlighted in bold script offer a lower and longer geometric option for clients requiring additional reach or drop.”

GIOS

GIOS is a legendary Italian brand, founded by Alfredo GIOS in 1972. One of the best cycling teams of 1970s, Brooklyn was the first big team using Gios bikes. The star of the team, Roger De Vlaeminck (born 24 August 1947) was described by another BElgian legend Rik Van Looy as “The most talented and the only real classics rider of his generation”. Nicknamed “The Gypsy”” because he was born into a family of traveling clothiers, he is known for exploits in the cobbled classic Paris–Roubaix race, but his performances in other “Monument” races gave him a record that few can match. His record in Paris–Roubaix earned him another nickname, “Monsieur Paris–Roubaix” (English: “Mr. Paris–Roubaix”).

In the 1990s, another big team Kelme used Gios bikes.

In 1991, Stephen Roche, chose GIOS bikes for his victories of that season.

Lots of victories won under one single color, the “GIOS blue”. Alfredo GIOS looked for a special color which fitted perfectly with the “stars & stripes”, design of the Brooklyn team jersey. After some tests, he chose the blue, because of its brilliant, electric, eye-catching and surrealist tone. Its originality spread quickly in the cycling context, becoming a milestone of the history of professional cycling. Even today, after many years, the distinctive “GIOS blue” colour continues being the main sign of the brand’s visual identity.

Nowadays, the GIOS company takes part in every international bike show and its worldwide sales team and customer service is today managed by two branches: GIOS ASIA/PACIFIC based in Hong Kong and GIOS EUROAMERICA with offices in Alicante (Spain), headed by Luca Tolmino GIOS, Alfredo’s son.

In 2016, GIOS has become the official technical supplier of the Colombian team “Manzana Postobon”.

Guerciotti Eureka SHM50 CCC Polsat Edition. Frame: Eureka SHM50 990 grams. Group: Shimano Dura-Ace Di2. Fork: Monocoque. BB Shell: Pressfit. Pedals: Look Keo Blade 2 Cr. Saddle: Selle Italia Flite. Seatpost: Dedaelementi Superzero. Stem: Dedaelementi 35. Handlebar: Dedaelementi 35 Alloy. Wheels: Ursus T47 Team. Tires: Tubolari Vittoria Evo cx. Bottlecage: Elite. Brakes: Tektro. “The model Eureka SHM50 has realized with a composition of carbon material composed by 75% 30tons High Modulus IMS60 carbon pre-peg + 20% 46tons Ultra High Modulus HS40 Carbon Pre-Peg+ 5% 60Tons Super High Modulus XN-60 Carbon Pre-Peg. The material system applied includes an high performance composite materials technology and special graphite fiber and epoxy resin. The same system is commonly used in aeronautics, aerospace and automobile industry. Eureka SHM50 is realized with an innovative process Advanced VaBm+EPU who ensures a kind of high level molding process, thanks to a unique technology who ensures essential feature like: light weight and extremely high values of STW (Stiffness To Weight). The system Advanced VaBm (bladder molding procces under vaccum control) is a process where the air inside the carbon layers will be pumped out during the molding process. The stiffness and strenght of carbon frame with VaBm increases around 3% compare with the regular bladder molding without vacuum control. Appling the sistem EPU (Expanded PU Shell) inside the lugs such as bottom bracket, aheadset tube, seat lug, it will increase the strenght of the carbon frame aroound 3-5%. The result of these working systems brings to a superior impact absorption of the frame for comfort riding, keeping at the same time a very good response and accelleration from the bike. This is the frame used by Team CCC Sprandi in the most important RCS races in the 2015: Giro d’Italia, Milano Sanremo, Il Lombardia and Dubai Tour.”

No, we didn’t make it ourselves and yes, it comes from a country where one might have noodles-not-pasta for lunch but we’re impressed with the quality of the frames we’ve seen from ADK and the fit, design, and geometry of this frame is right on the money – thanks, Columbus! If you’re looking for a light/strong/comfortable carbon race bike that won’t break the bank but will provide a good alternative to all the GianTrekalized bikes out there we think you should be on this.”
