so while i was checking out SOMA’s site today, i stumbled across THIS — sugino’s new, infinitely easier to swap rear cog system, clearly based on MICHE’S version of the same.

the way it works is that instead of threading on a cog and then threading on a lockring, as per the usue, instead you first thread on a "carrier," which is a toothed piece that corresponds to teeth on the cogs. once that piece is on, you swap cogs by hand, laterally. you still use a lockring to secure the cog after installation, but both the lockring and the threaded carrier piece install with a PARK BBT-9 BB TOOL.

so what’s the benefit? well, you no longer need to rotafix or chainWhip that cog off when you switch it. so let’s say you’re a trackie out at the velodrome for the day, racing. your rear cog switches just went from 3 minutes to 30 seconds. or let’s say you’re a long-distance fixie rider, traversing a fundraising ride or a multi-day trip. same again. swap that cog faster than refilling your water bottle.

the sugino system is alloy, and as such is not recommended for hardcore urban fixie mashing. but the whole set (carrier, lockring, and 16t/17t/18t cogs) is only a buck thirty at the above link, which is JUUUST about the same cost as three cogs and a lockring anyway.

VERY cool.
