When seasons change from road to cross you shouldn't have to hang up your bike until spring, but that doesn't mean you'll want to keep running the same gear ratio through the slush and mud. To make direct-mount chainring swaps a breeze we offer the 2INPower DM Spider Nut tool. This sleek and handy tool is crafted from aluminum for total durability, and pairs with your bottom-bracket tool to get your new chainrings torqued just right.
This tool works on the 2INpower DM interface and on the UBB 4630 in all variants except for PF30.
The outer interface of the tool is driven by any Hollowtech II tool, such as the Park Tool BBT-9.
