Unior master chain tool
The absolute top of the Unior range. This high-quality tool is designed with a robust frame and extremely precise spindle threads, ensuring smooth and controlled operation.
The long handle allows you to effortlessly create extra leverage, ideal for loosening even stubborn chains. The floating chain support ensures perfect alignment and support. Compatible with all 6 to 12-speed derailleur chains, including SRAM AXS and 1/8" single speed chains. Also suitable for Campagnolo 11- and 12-speed chain pins.
This tool comes with three interchangeable supports:
- Single link support (pre-assembled)
- A double link support for better grip
- A specific support for SRAM AXS chains
The case also contains a handy spare compartment with an extra chain pin.
Unior pro chain tool
This professional tool is suitable for almost all bicycle chains.* Equipped with a ball bearing pin, it ensures a straight, precise drive every time. An additional practical feature is the integrated auxiliary holder for loosening stuck chain pins.
*Not suitable for SRAM AXS Flattop chains — for these, it is best to use the master variant.
Unior chain tool (standard)
A simple but reliable tool for every cyclist or hobbyist. Thanks to the ergonomic handle, you can work comfortably and with minimal effort. Ideal for occasional use or for those just starting out.
Unior mini chain tool +
Small but powerful! This compact version works exactly the same as the model on Unior's multi-tools. Handy to take with you on the go and equipped with a flip-out handle.
Master link pliers
These pliers are the quick solution for loosening a chain for cleaning or replacement. Fast, efficient and easy to use.
Chain rivet pliers
Similar to a classic chain punch, but uses a replaceable rivet for a longer service life. Thanks to its 240 mm length, it provides sufficient leverage and can be operated with one hand.
Pro chain wear indicator
This precision tool makes it easy to measure chain wear. Place the pins between two links, press down on the arm and read the result on the integrated gauge window.
Chain wear indicator (go/no go)
Simple, but effective. This “go/no go” gauge indicates at a glance whether your chain needs replacing. Indispensable for both hobbyists and professionals.
