>>1522795I have something like that. The job it does doesn't meet my standards. If I'm cleaning chainrings and cogs I want the CLEAN, not 'sort of clean'.
As previously stated I've tried finding a spiral brush that's reusable but I've yet to find one that's the right diameter, they're all either too small or too big to work. What I'm doing with the pipe cleaners is the best tradeoff I can manage at this time. It's not like I do this every week or even every month, and the average de/n/izen probably doesn't clean those more than once or twice a year.
If you can find a sprial brush with nylon bristles that'll fit between 10- and 11-speed chainrings and cogs, post it, I'll buy a couple and try them.
Speaking of Park Tool, I'd also like to recommend this dummy hub for when you're cleaning your chains. It keeps all the grunge from your chain from getting all over your cassette.
