Calling the new single speed cog from Absolute Black simply a “cog,” would be doing the beautifully CNC machined component a disservice. Designed in the UK, and manufactured in Poland, this fancy bit of 7075 Txxxx Aluminum has several unique features.
What elevates this beyond the level of a simple cog is the narrow wide alternating tooth profile, which has now become common place on front sprockets. In this implementation, the design offers additional strength, better wear characteristics, and has the added benefit of better chain retension. This means as your chain stretches, the cog will prevent the chain from dropping.
The one caveat, is that cog is not compatible with half link chains, and will perform best with either a 10 or 11 speed.
Available in a 16T, 18T, and 20T, although the larger and smaller cogs will not be available till June 25th, price will vary depending on region. For those in the US, retail is $39.99. Not bad for the lightest single speed cog on the market! Current claimed weights for the anodized beauties are 16T(23g), 18T(24g), 20T(29g).
The base of the cog is 7mm thick, so it will not mar the finish of an aluminum free hub body. Also, the teeth have been positioned centrally, so you can always flip the cog to prolong the wear life of the cog.
If you ride your single speed every day or could in any shape, way, or form, be dubbed a Clydesdale, then stay tuned for the future steel version, which will be launching soon.
