On-One Groove Armada Single Speed Sprocket
3/32in Shimano splined. 9spd spaced - stack 'em up and run 'em with a mech, or singley for single speed. Assymetric for chainline tuning. Groove Armada tooth cleaning system. Oh, and we forgot to say... They've got a big wide bottom (though not as big as fat mandy that lives up the road from Shauns). We'll take a better pic sometime, but this is a good idea if fitting to a non-steel freehub body - wide based cogs spread the load and don't dig in.
Base is 4mm wide - plenty wide enough not to dig in.
About the On-One brand.
On-One is an independent British manufacturer of bikes and cycle components based in Yorkshire, UK.
Known originally for classic, award winning steel frames - such as the On-One Inbred, On-One Pompino fixie and On-One 456 hardcore hardtail - On-One have continually embraced modern manufacturing materials with the Carbon Whippet, Scandal and the world's first long travel carbon hardtail, the Carbon 456. On-One are also known for their excellent range of singlespeed and 29er mountain bikes, carbon and steel rigid forks.
In addition to steel, carbon and titanium mountain bike frames On-One are known for their excellent value range of mountain bike parts and finishing kit. After enjoying success with CNC stems, seatposts and cult MTB saddles they released a legendary line-up of alternative handlebars to critical acclaim. Since then On-One have expanded into custom mountain bike wheels and are developing a range of folding 26" and 29er MTB tyres and clothing too!
On-One's aim is to offer high-spec mountain, commuter and fixie bikes direct to the consumer, cutting out the middleman and slashing prices to the absolute minimum. They've been at the cutting edge of the British mountain bike scene for years and are now branching further afield with new international websites opening across the world.
