Hydra End Cap Kit

They're endcaps...

Familiarity:

I've put it through the wringer

I mean, how much is there to review? But saying that, they're machined to very exacting tolerances, like all I-9 hardware. They fit snugly on the axle while still being easy to pop off when you need to remove them, so 5 stars for the lowly little endcaps! I was a little miffed that the torque cap endcaps from my old I-9 Torch hubs didn't fit the Hydras, but I guess that's the cost of progress. Looking at them, I understand the engineering reason for the change, so ok - the new axle design should reduce wear on the bearings.
