Most people will have some sort of chain tool as part of a mini-tool they carry on rides but for home use ? cleaning, maintenance and rebuilds ? a workshop quality, full-scale link extractor makes life much easier.

Both the Unior and Park tools are bigger, tougher versions of a standard tool and the extra leverage of longer handles makes the initial pin crack-through much easier.

The Chainbot has ratchet arms like a posh corkscrew and a folding handle. This makes for a neat product that?s surprisingly ergonomic. Quirky looks do it no harm either. Park?s CT-3 is easily the most functional, but the flat handle could be more comfortable.

Verdict

The Unior tool works well, but doesn?t feel as well made as either of the others and seems expensive for such a basic item.

Topeak?s Chainbot, however, works well, feels nice and is a great little something for the cyclist who has everything. It?s also light and small enough to carry on the bike.

The Park CT-3 ticks every box, with a sturdy construction and simple action.
