Break Chains Quickly And Easily With Unior's Flagship Bike Tool

The most advanced chain tool in Unior's range, the resdesigned Master Chain Tool features a machined body and precisely made spindle threads for smoothness and ease of use.

A large handle gives extra leverage and breaks the chain easily.

The Unior Master Chain Tool features a floating chain support for perfect positioning and support of any chain, and it works with all derailleur chains from 6-12-speed. It is compatible with SRAM AXS chains and also works nicely with 1/8" single speed chains.

Unior has also built in support for peening Campagnolo's 11, 12 and 13-speed chains.

The tool comes with three different interchangeable chain supports; preinstalled is a single link support, which is accompanied by a wider double link chain support for extra grip on the chain and a dedicated SRAM AXS FlatTop chain support.

A hidden compartment in the handle carries an additional replacement chain pin.

The 1647/2BBI Master Chain Tool also features a modular design, allowing for compatibility with future chain types simply by changing the support plate. Included are 3 supports with the tool, 2 for standard chains and 1 for SRAM AXS FlatTop chains.

The second standard chain support is this shorter version. If you're a mechanic on the go, the shorter version will pack into your tool case that much easier.

Also included is Unior's SRAM AXS FlatTop compatible chain support. Not everyone will need it, but if you do, it's there.

Comes With:

  • Long and short derailleur chain support (compatible with 6-12-speed derailleur chains)
  • Dedicated SRAM AXS chain support
  • Campagnolo chain pin blocker
  • Replacement chain pin
  • Compatible With:

  • All derailleur chains from 6-12-speed
  • SRAM AXS flat top chain
  • Most single speed 1/8" chains
  • Campagnolo 11- and 12-speed chain peening
