Whether you're tearing through city streets, commuting, flying through roaring crowds in a fixed-gear crit, or racing on the velodrome, the Allez Sprint Track is right at home. At the heart of the Allez Sprint is our D'Aluisio Smartweld Technology, which strategically places more welding material where it's needed, resulting in an aluminum bike that's more compliant and considerably stiffer. How stiff, exactly? It's the stiffest alloy bike we've ever tested, let alone made. Drawing inspiration from the Rider-First Engineered Tarmac, this frame also has a unique down tube, bottom bracket shell, and head tube, plus fork sizes that correspond to frame size. This ensures uniform performance across the entire size run. To make sure that every single watt you produce gets transferred to the road, we gave it short chainstays that create an extremely stiff and rigid rear triangle. But it goes beyond just pure rigidity, as the hydroformed tube shapes have also been aerodynamically optimized to slice through the wind, while also providing tons of built-in compliance. - E5 Premium Aluminum frame with Allez D'Aluisio Smartweld Sprint Technology refocuses weld locations, allowing for more material to be placed strategically for increased stiffness and compliance where you need it most. - Our top-tier S-Works FACT carbon fiber fork provides incredible stiffness and front-end steering response, while also efficiently absorbing road chatter. - The Venge FACT carbon fiber seatpost acts as a stiff, aerodynamic perch for your saddle.
The Big Block represents our vision of the ideal track frame for the modern fixed-gear rider. This is the track bike that All-City has always dreamed of owning and they are proud to make that dream available to you. It was designed first and foremost as a true competition-ready track frame but was destined to see usage beyond the velodrome, so they made some tweaks to the equation. Instead of the track bike norm 25c max tire clearance, it fits a 32c cross tire and has a single set of water bottle mounts for all day in the saddle. The front and rear of the bike are drilled out for a brake, so single speeding (or double brake fixed) is no problem. The proprietary 612 Select double-butted cro-moly steel soaks up bumps and sprints like a champ. Each piece of tubing on every frame size has been carefully scrutinized and specifically chosen to create the best ride possible. This includes butting placement, tubing diameter and wall thickness. The package is finished off with a custom headtube badge, brazed-on seat collar, custom bottom bracket and signature Hennepin Bridge dropouts. All-City added an E.D. coating for rust prevention before applying a classic wet paint finish. Attention to detail is All-City's mantra and it shows in every aspect of this meticulously-designed, beautifully-constructed track racer.
