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to the fork steerer, instead of the twin M5 bolts previously used, and the Allen bolts used on the original Arx have been replaced by no-strip Torx bolts.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)

The Box Three E-Bike Cassette offers high gears with more teeth to withstand the rigors of modern E-Bike riding. Adding an extra tooth to each of the three highest gears provides increased durability and decreased wear by distributing the load over a larger area! The Box Three E-bike cassette draws from both of its Box One and Box Two siblings to create a sensible all-rounder. All cogs are stamped from steel and subsequently, the larger ones are pinned to steel spiders. The main difference here versus Box Two is the use of additional weight-reducing holes on the cogs. FEATURES - Our Best All-Rounder Cassette - Steel Stamped Cogs - Steel Stamped Spiders - Ultra-Wide Ratio with Consistent Progression COMPATIBILITY - Box One Prime 9 Chain 126L DLC Black - Box Two Prime 9 126 Link Chain Nickel - Box Three Prime 9 126 Link Chain Polished - Box One Prime 9 Rear Derailleur - Box Two Prime 9 X-Wide Rear Derailleur Black - Box Three Prime 9 X-Wide Rear Derailleur Black - Box One Prime 9 Single Shifter Black - Box Two Prime 9 Single Shifter Black - Box Three Prime 9 Single Shifter Black

New Super Record 12 Speed chain: slim, robust, smooth and precise. The chain, in all its apparent simplicity, plays a critical role in the cyclist's safety and in optimizing the entire transmission mechanism. The new Super Record 12 Speed chain also had to be redesigned from scratch to work with all the other new transmission components. Therefore, the first and most important objective was reducing its overall dimensions. Its width is now 5.15 millimeters, thanks to the new pins which are perfectly aligned with the links’ outer surfaces. The second objective was safeguarding its performance. This was achieved thanks to the Ultra-link system that makes the chain safe and durable, and a special treatment that guarantees extreme smoothness and precision shifting.
