Whip-It chain whip.
The Whip-It was the second tool developed by Abbey Bike Tools. A chain whip is a pretty simple tool, but the Whip-It maximizes function and simplicity. The Whip-It is made from a 12" length of stainless steel to give you enough leverage to loosen even the most stubborn cassettes. The Whip-it's round handle provides comfort surpassing other flat bar style chain whips on the market. The icing on the cake is that Abbey's signature tool, the Crombie, stores inside the handle of the Whip-It! This means the two tools you use together, get stored together, and travel together, giving you less clutter in your tool box.
The Whip-It comes in two versions, one for single sided tools that use a 3/8" handle and one for the 1/2" handle of the dual sided tools.
