Review by bike_racerReviewed 6/1/2020by bike_racerCompetitive RacerHuntsville, AL1 of 1 customers found this review helpful.Very handy tool for chainbike cleaningWorks great on my road bike and thru axle mountain bike. Allows me to use my Park Tool chain cleaner to clean the chain and not get grimy solvent and water all over the rear wheel. This is one of those tools that you can probably get by without but once you have one you'll be glad you purchased.

Review by LarryReviewed 11/1/2022by LarryMontreal, CanadaClever and useful Wanted one for a while. Easy to use and makes drive train cleanup way easier than before. The chain is held under tension while reaching any part of the drivetrain from any angle. Worth it.

Review by SHBiker Reviewed 11/28/2020by SHBiker Cycling Enthusiast4 of 4 customers found this review helpful.Does the jobWorks well and as advertised, allowing easier drivetrain cleaning with wheels off, and is also useful for transporting bikes with the wheels off. I will say, though, wish I had done a bit more research before and known that the compatibly with thru-axles is literally just that the little plastic circle that hold the chain comes off of the provided dummy QR-skewer and slips on to your own removed thru-axle. I would not have paid 20 bucks for just a little plastic circle that slips onto my own thru-axle lol... I did end up using it once to transport a QR bike that I recently sold, and will maybe one day own another bike with QR, but as of now I only use the plastic ring for my thru-axle bike. So, all in all I'm glad to have the tool and think it's useful but I also think that Park Tool should sell just the 12mm thru-axle compatible plastic ring by itself for like 10 bucks.

Review by Bike_racerReviewed 9/1/2020by Bike_racerCompetitive RacerHuntsville, ALVery handyGreat little gadget. Not cutting edge technology - just a simple tool for making it easier to clean your drivetrain. This allows you to clean your chain, rear mech, and chainrings without getting degreaser/cleaner/solvent all over your rear wheel. Works great on traditional quick release hubs as well as thru axles.

Review by dropperfreeReviewed 2/12/2020by dropperfreeCompetitive RacerStumptownSimple and IdealRemoving the cassette to apply lube or clean a chain is the way to go. This works with qr and 12mm thru axles. Great also for keeping a dirty chain off the frame while the wheel is off. Cant recomend this enough.

Review by TomReviewed 11/21/2020by TomPortlandMakes cleaning a bike a breezeGreat bang for the buck, there are some cooler options on the market, Robert Axle for example, but this works great for my needs. Mad I waited this long to get one. So easy to throw on, keeps the chain out of the way, plus you can shift and the hub moves to accommodate the new chain position. If you hate to clean your bike get one of these it will really help.

Review by PalouseRiderReviewed 11/7/2019by PalouseRiderCycling EnthusiastPullman, WAUse a dummy hub for no fuss chain cleaning.I use the dummy hub to clean chains on all my bikes (road, triathlon, and gravel). The hub works equally well on quick-release and through axle wheels.

Review by AnonymousReviewed 6/5/2018by AnonymousCompetitive Racer1 of 1 customers found this review helpful.A must haveSimple and easy to use. However, i found that for some frames it would not work. I had to add a spacer at the end to get it to work on frames with narrower dropouts.

Review by CaptainPicoReviewed 2/19/2018by CaptainPicoCycling EnthusiastPico Rivera, CAChain scrubbing made easyI have used the Park Chain Scrubber for many years with my rear wheel on the bike. I would occasionally bump the plastic scrubber on the spokes. With the dummy hub you can remove the rear tire and use the scrubber without having to balance it and be mindful of the spokes. I wish I had purchased this long ago.

Review by frankodemReviewed 11/9/2020by frankodemCycling EnthusiastDallas ORWorks GreatHolds the chain in place and out of the way with the rear wheel off. Had an older version and another make of this type of product. This is a far superior product that is well designed.
