A stem may not seem like the most exciting bike part, but it's in our DNA to care about it in great detail. After all, no other part has such a dramatic effect on your riding position and thus your speed, comfort, and enjoyment. With the APTO, 60 years of innovation and elegance in 3T stem design comes together in a moving sculpture. Steerer Clamp: Double bolts hold the steerer securely and provide redundancy for extra safety. Reverse Faceplate Bolts: These clean up the faceplate for a more elegant design, particularly in combination with our new drop bars. Classic Rubber Logo: The 3D rubber logo is a nod to the iconic 3T stems of yesteryear. - Material: Alloy 6061 - Steerer diameter: 28.6mm (1 1/8") - Handlebar diameter: 31.8mm - Key size: 4mm Allen key - Steerer bolt torque: 5Nm - Faceplate bolt torque: 5Nm

Zero25 is a lightweight, universal seatpost with a twist: it's two seatposts in one. The two clever, reversible saddle rail clamps transform the post from zero saddle setback to 25mm setback. All that's needed is to flip the clamps from one side of the seatpost head to the other and the offset changes. No more problems with getting the wrong seatpost or needing another one when you change the type of saddle you use—it now takes 30 seconds to transform your seatpost. And, the best news is that, despite the double functionality, the Zero25 is even lighter than our previous seatpost. Zero25 can handle any type of seatpost rails, including round rails and oval-shaped carbon rails.

Hubs typically seem to fall into two general categories: light and very expensive or heavy and cheap. With this typical bike industry paradigm, we saw an opportunity. You see, for years we've been using high-end geared hubs from the manufacturer of our track offerings on our personal bikes. They are very lightweight (peep the specs) and just plain work. We decided to finally make those hubs available to you and corner the market in our own category: lightweight, affordable, and incredibly practical. We've ridden them on all kinds of bikes from the Electric Queen to the Mr. Pink and we're in love. They are reliable, crazy light (60 flipping grams!) and very reasonably priced. Rim brake hubs include quick release end caps and skewer. On all models we spec high-quality made in Japan stainless-steel sealed bearings. Oh, and we've got polished options as well. Kind of a big deal because polished hubs have become a rarity. - Weight: 60g - Non-Drive Side Center to Flange 32mm - Drive Side Center to Flange 32mm - Non-Drive Side Flange Diameter 30mm - Drive Side Flange Diameter 30mm

New Sheriff hubs are the ultimate in track racing hubs. They minimize weight with larger cutouts in the flanges, lightened axles, shorter bolts, and slimmer end caps than previous versions. The result is a hubset that weighs a mere 432g, 198g for the front, and 234g for the rear. This makes it one of the lightest track hubsets in the world, a figure even more impressive when you consider that All-City didn't eliminate the usefulness of a fixed / fixed or fixed / free option as most racing hubs do. They feature the finest Japanese manufactured 6902 bearings which roll incredibly fast and smooth while retaining excellent seals for all weather, all-day everyday durability.

The Pursuit Special is All-City's addition to the pantheon of high end track chainrings. They were designed in house by track racers for track racers and are optimized for weight, stiffness, and engagement. These beauties are cnc’d in the USA and utilize a proprietary tooth profile for smooth and quiet operation. The 49-52’s utilize a solid body design with reliefs in the back for weight savings, while the 46-48’s have full cutouts. In sticking with the theme of their aluminum track bike, the Thunderdome, All-City named these rings after Mad Max’s car, the Pursuit Special. - Material: 7000 Series Aluminum - Ring Position/Type: Single
