Named for the perching pose of the insect, the Birzman Damselfly chain tool is a dab hand at pushing out chain pins, but it's expensive.
The Damselfly's main body and handle are aluminium which gives a decent feeling of strength especially when you're going through those first couple of turns to get the pin started.
It's very well made to with a very smooth screwing action and that Y-shaped handle does allow a decent hand movement whether you're spinning back or applying pressure to the pin. At just 40g you're not to going to notice it in a saddle bag or back pocket.
The little prongs that position the chain are quite shallow, though, so you have to hold the chain in place while you're removing the pin.
All of this design and quality comes at a price though. At £34.99 it's a lot of loot for something you're probably not going to use that often.
Birzman state that its 9-10 speed compatible and I also didn't have any issues separating a 1/8in track chain.
Overall the Damselfly is a good design in terms of ergonomics and materials but the shallow chain guide and especially the price take the shine off. It's too expensive for an emergency tool to keep in your saddlebag and if you're looking for a workshop workhorse there are others that work better.
Nifty design and top quality but the performance falls short especially considering the price.

if the Damselfly shared the deep chain guides and spring of the much cheaper Birzman Light-er it would be a winner all round but the fact that you have to hold the chain in position with your thumb is a bit annoying.

With a background in engineering dabbling as a CNC programmer/machinist, draughtsman and product development engineer how a bike is made is just as important to Stu as how it rides.
He knocked out his first road.cc review back in 2009 and has been chucking bikes around the west country ever since and the only reason he climbs is so that he can descend like a nutter down the other side. After years as a competitive time triallist Stu is on the lookout for a new form of competition after realising that the choice of a few glasses of wine in the evening versus riding up and down dual carriageways at 5am was becoming very one sided.
