Brit/Pole CNC wizards at it again…
Using the tooth profile developed for their own Spiderless Chainrings, Absolute Black claim that their Cogs help to keep a stretched chain in place on rough terrain- probably not a bad idea for the sort of maintenance-averse riders singlespeeds tend to attract. The company also notes that the narrow/wide profile makes for a cog sprocket that “should outlast any other one made from aluminum.” Faint praise, perhaps, but a steel version is on its way. To take full advantage of those fancy teeth, a 9/10/11s chain is recommended- though anything designed for 1s-8s will work as well. Half-links will make for a very sad drivetrain- so don’t use ’em.
Of course, the Cogs also make for a great an excuse to show off Absolute Black’s mastery of both CNC and camera. Being alloy, weights are impressive: 23g, 24g, and 29g for 16t, 18t, and 20t variants. Perhaps the best part is the pricing: £29/$40 seems quite reasonable for such a unique, lightweight, and attractive piece of kit- especially one made in the EU (Poland, to be exact). 18t cogs are shipping today, the other two can be ordered now for shipment in three weeks’ time.
Nice, run a thick thin chainring on the single speed already think this could replace the bmx sprocket when i have the need for some new shiny…. or matt blacky
*Insert ‘it’s a sprocket, not a cog’ rant here*
pretty
That looks fabulous and given the work involved is a bargain at that price.
Kinda pointless? 2x as expensive for something that’ll last a fraction of the time. And an expensive mechanical solution for a niche of singlespeeders who are adverse to spending money maintaining the only maintenance task on their bike?
The only niche it’d work on is non SS frames and not using a tensioner and only then in the minority where the ‘magic ratio’ falls on an even number and didnt need a half link!
TINAS – You’re forgetting those with a chain tug, this will save those people seconds of turning an allen bolt, or wingnut a couple of degrees clockwise.
