CHOOSE THE LONGER ROUTE. CLIMB HIGHER MOUNTAINS. THIS SMOOTH-RIDING ENDURANCE ROAD BIKE IS MADE FOR LONG-DISTANCE RIDES ON ALL TYPES OF ROADS. KEY PERFORMANCE FACTORS Engineered compliance Advanced Composite frame is engineered for endurance road riding. The D-Fuse seatpost and handlebar absorb road shocks and vibrations, and its smooth ride quality means you’ll feel less fatigue on long rides. Total control Seamless disc-brake integration including flat mounts and 12mm front and rear thru-axles produces more consistent braking power for better control, even in wet weather and on rough roads. Versatility Endurance road geometry, plenty of tire clearance (up to 35mm), and disc-brake integration allow you to tackle a variety of roads and conditions, from smooth pavement to rugged mountain passes. TECHS & FEATURES ADVANCED COMPOSITE TECHNOLOGY Giant’s High-Performance Grade raw carbon material is used to produce this custom frame material in our own composite factory with a high stiffness-to-weight ratio. The front triangle of these framesets is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction. D-FUSE TECHNOLOGY The D-Fuse seatpost and handlebar were designed to function as a system, absorbing road shocks, and vibrations so you can ride farther, faster. OVERDRIVE Giant’s original oversized fork steerer tube technology. Designed to provide precise front-end steering performance, the system’s oversized headset bearings (1 1/4" lower and 1 1/8" upper for road, 1 1/2" lower and 1 1/8" upper for mountain) and tapered steerer tube work in conjunction to provide optimal steering stiffness. COMPACT ROAD DESIGN Introduced by Giant with the professional Team ONCE in the 1990s, Compact Road revolutionized the look and feel of high-performance road bikes forever. A downward-sloping toptube (from the headtube to the seattube) creates smaller front and rear triangles for a lighter, stiffer bike. It also makes it easier for riders of all sizes to have a perfect fit. TUBELESS SYSTEM Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.

A BIKE FOR THE WAY RIDERS RIDE Caledonia doesn't fit in a box nicely, and we like it that way. It was conceived on our Thursday night rides-routes that often play fast and loose with 'road ride.' As we tried to stuff bigger tires into our R5s and streamline our Asperos, a new kind of bike was born. When we design a bike, we start with our library of tube shapes. These shapes are tubes we've used on other models that we know to have various qualities-aerodynamic, stiff, ultralight, etc.-and they help get us to the refinement stage on a bike more quickly. In the case of Caledonia, we wanted durability, lightweight, and aerodynamics to be in balance and selected a package that achieved the performance demands of this kind of race bike. Caledonia uses a standard round bar, stem, and seat post, giving riders the option to build their ultimate ride without compromise. Integrated accessory mounts and hidden fender mounts keep the bike's refined lines so you can ride with lights and computers in a downpour and still look fast. Because we all know if it looks fast, it probably is. Rather than designing multiple versions of the bike with various fit profiles (R5, R-Series, etc.) like we've done in the past, we designed a system that enables a broad range of fits on a single bike while maintaining the aesthetic and functional cleanliness we demand. Modern road riders are looking for bikes to handle long-distance, high pace, no limits, and offer maximum fun. By placing lower modulus carbon in key areas to mitigate the brittleness of hi-mod fiber-the Caledonia delivers performance, comfort, and speed. Oh, and you can fit a 34mm tire in there. Or 31mm with fenders.

HAUL ASS, NOT CARGO A new breed of rider is emerging-one who loves the freedom and exploration that gravel culture was founded upon but who has a hunger to ride hard, to go all out, and to explore not just geography but personal limits. This frontier requires a new kind of gravel machine, one engineered not to roam the trails, but to race them. For these athletes, we engineered Aspero for pure, unapologetic speed, ready to take down finish lines, KOMs, PRs, and FKTs. A bike built without limits, for the riders looking to test them. It's stiff, Classics-racing stiff, and performs like you'd want a road bike to perform off-road. We think that makes sense, and it's what we were trying to do when we were stuffing bigger tires into our existing frames and swapping in aftermarket forks to get a 40mm tire up front. The flip-chip in the fork-we call it the Trail Mixer-keeps the trail measurement consistent whether you choose 700c or 650b tires. This maintains the bike's personality and handling characteristics when you switch from mid-fats to full-fat. There are as many different ways to do gravel as there are gravel bikes these days, but if you're toeing the start line, looking to stay with the lead group, and contend for the victory, Aspero is the bike to get you there.
