3T Arx II Pro
$79.99
3T's Arx II is a subtle refresh of the well-liked Arx alloy stem, which has found a place on every sort of bicycle since its launch in 2007. The faceplate is drawn in tighter at top and bottom for a more ovalized frontal appearance, while retaining the cutout 3T logo. The sides of the extension are slightly flattened for a more sculpted look by comparison with the tubular section of the first-generation Arx. A single M7 bolt clamps the stem to the fork steerer, instead of the twin M5 bolts previously used, and the Allen bolts used on the original Arx have been replaced by no-strip Torx bolts. - Stack height: 40mm - Weight: 135g (110mm)
3T Ergonova Pro
$119.99
3T's Ergonova Pro Handlebar features a wider, flatter top section that provides more surface area for your hands. A tight radius where the brake lever sits and a gradual bend make it easy to reach your levers while in the drops. Its triple-butted aluminum construction is lightweight and strong. Cable grooves on the underside provide a smooth feel when you're on the tops.
3T Zero25 Team Stealth
$160.00
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.

All-City Pursuit Special
$79.99
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
All-City 612 Track Crank
$100.00
The 612 Track Crank is an extremely stiff and strong 144mm BCD track crank. It’s at home as much on the busy avenues of your city as it is on the boards of the velodrome. All-City sweats the details, so the 612 (Minneapolis’ area code) is cold-forged, resulting in a tight grain structure. The upshot is that it’s strong, which means more riding and less worries for you. It utilizes the classic JIS square taper spindle and comes with a color-matched, 46-tooth, 1/8th chainring.  - Recommended Spindle Length: 110mm - Spindle Interface Type: square taper JIS - Bolt Pattern: 5-bolt - BCD: 144mm - Chain Compatibility: 1/2-inch x 1/8-inch - Weight: 726g w/ ring and bolts - Bottom bracket and retaining bolts not included
