SaniMomo Upgraded 12mm Thru Axle Chain Keeper Holder Bike Clean Transport Tool Hub

Its a small plastic wheel which is round! fits nicely on a 12mm through axel, holds the chain well.It does have a few nice features; magnetic master link holders, measurement marks, 2 foam O-rings and a tidy case to store it in. It all seems well made.Not sure about the inclusion of the foam O-rings, unless you have a perfectly clean chain, they with get filthy and hold the dirt immediately. but hey, they included them, so I cant complain about something extra.

One of those little bits of kit that just makes life a little easier when cleaning the bike or more specifically, the drive train, with the rear wheel off.Wish I'd bought one years ago.

Works as intended. Stops my chain damaging paintwork when I have the rear wheel off. Which is great when I’m driving with the bike in the boot. Fits 12mm axle perfect. Good price. Delivery was reasonable. Chuffed
