Nice For Cleaning

  • Familiarity: I've put it through the wringer

This is a nice little gadget that makes it possible to clean your drivetrain with the wheels off. Works as described!

No brainer

excellent tool for cleaning your bike or any maintenance yo need to do, really it doesn't get any easier

Worth Its Weight In Gold

  • Familiarity: I've used it once or twice and have initial impressions

I got my MTB up on a stand to give it a much-needed through cleaning which meant pulling the wheels (I watched the Park Tool vid on YT and basically did all those steps). To be able to pop on this dummy hub in 5 seconds with the QR lever is priceless... you HAVE to in order to clean the chain properly and not have it flopping around. BTW, the Park Tool Chain cleaner is also superb. In the AZ desert dust that chain doesn't get muddy/grimy, it gets gooey and abrasive so yu have to use the chain cleaner tool and the ONLY way to make that happen is with the dummy hub. Make sure you get the right one. I don't have a through-axle on my less expensive Marlin 7 so I get the quick release hub, but they do make one for through-axle.

Spin drivetrain without wheel in bike

This tool allows you to work on drivetrain issues while the wheel is out of the bike.
