Item # ABY0001

Road and mountain maintenance.

Cassette tools are a home shop essential. However, if you've ever experienced the lack of confidence that wrench-held cassette tools inspire, it comes as no surprise why Abbey Bike Works created the Dual Sided Crombie Tool.

This tool combines both the Shimano/SRAM standard on one side and a Campagnolo standard on the other. A long handle provides ample leverage, and it's shaped to prevent your hands from suffering while removing stubborn lock rings. Additionally, the tool's long teeth provide sufficient purchase on soft, aluminum lock rings.

The Abbey Bike Works Dual Sided Crombie Tool is constructed from stainless steel and is compatible with Campagnolo, Shimano, and SRAM cassettes.

  • Dual sided cassette tool: Shimano/SRAM side and Campagnolo side
  • Stainless steel construction with precision machined spline

Rare for me to give a tool 5 stars

  • Familiarity: I've put it through the wringer

This tool is an absolute must for anyone who works on their bike regularly or is a professional wrench. Back when I worked in a shop, I had to put a lock on my tool box purely because this tool was in it and my coworkers kept stealing it.

The finish of the tool is beautiful, welds are perfect, and it has lasted me basically since they first came out with it a couple years ago with no notching or warping of the splines. Also works great for centerlock lockrings, without having to remove hub endcaps. Genuinely feels like a tool I will never have to replace.


  • Familiarity: I've used it once or twice and have initial impressions

This is probably the most obvious tool in the history of cycling that hasn't become a commonplace sight. The fact that it's built by Abbey is just an added bonus--no cheap, throw-away, blue-handle nonsense.

This is such a convenient tool

  • Familiarity: I've used it several times

I love that it's one piece and that it has both campy and shimano/sram. No more working with 3 tools (wrench, cassette tool and chain whip) to remove a cassette.

If you wrench, you'll appreciate it!

  • Familiarity: I've put it through the wringer

After countless years of using a lockring tool in conjunction with an adjustable wrench, the Crombie tool is very nice to use. No fumbling around and it works great. The construction quality is excellent and the ability to store it with the Abbey Chain Tool seals the deal for when you need to travel with it. If you're a wrench you'll really appreciate this one!
