K-Edge Dirt ACS Chain Device
K-Edge Dirt ACS is designed to help prevent chain suck and the subsequent damage that can occur to the chain stay. This is especially critical for mountain bikes that have carbon chain stays – both hard tails and suspension frames.
Top Features of the K-Edge Dirt ACS Chain Device
- Material: 6061 T6 aluminium and stainless steel
- Fitment: Mounts by replacing 2.5mm spacer on out-board bearing bottom bracket cups
- Weight: 26 grams
- Anodized colours: Black and Red
The adjustable pucks are compatible with a variety of chain ring sizes. Includes pucks for triple and double chain ring setups.
The K-Edge Dirt ACS is compatible with 68 and 73mm bottom bracket shells using outboard - external cup bottom brackets. The K-Edge Dirt ACS attaches to the frame by replacing the 2.5mm drive side spacer.
Most external bottom bracket configurations have either one or two 2.5mm spacers on the drive side (68mm bottom brackets have two 2.5mm spacers on the drive side and 73mm bottom brackets have one 2.5mm spacer).
If your particular Crank/BB setup doesn’t have at least one 2.5mm bottom bracket spacer on the drive side, the K-Edge Dirt ACS is not compatible.

About Chain Devices & Bash Guards
Chain devices fit in various places around a mountain bikes transmission and help to eliminate chain suck and chain slap when riding over rough terrain or landing from big drops. There are a number of fitments, some frames have ISCG mounts which are lugs on the drive-side of the bottom bracket shell and allow direct fitment to the frame, other chain devices fit in between the bottom bracket and frame and require a specific bottom bracket with a larger drive-side cup, and finally there is the type that clamp around the seat tube in place of the front mech. Also within this section you can find single speed chain tensioners which fit in place of the rear mech and take up any chain slack.There is also a selection of wheel tugs which stop you pulling your wheel over in horizontal dropouts.
About the K-Edge brand
K-Edge Cycling Solutions brand was born from one simple product, Kristin Armstrong’s Chain Catcher - later to be called K-Edge Chain Catcher. The K-Edge Chain Catcher is a purposeful design that was engineered for a single goal: help Kristin Armstrong win the Gold at the 2008 Olympic Games. While we wouldn’t be so arrogant to suggest the K-Edge was the reason Kristin took gold, it’s a common sense design that provides functional and mental advantages for high performance cyclists. The K-Edge is also perfect for anyone who likes to keep their chain in place, improve shifting performance, and protect their frame from damage caused by a derailed chain.
