PDW The Bird Cage



A top performing bottle cage that brings a bit of fun to your bike

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

PDW stands for Portland Design Works who as you can probably guess are based in Portland. We're talking US of A here though for the makers of this The Bird Cage bottle holder - not on the coast of Dorset.

Since 2008 the guys at PDW have been coming up with various bits and bobs to customise your bike from bar grips, to racks, mudguards and plenty of things in between. They've now turned their attention to the humble bottle cage.

The Bird Cage is as you can probably see a bird shaped sheet of 5052 grade alloy rolled to create a holder for your bidon. Coming in either a chrome plated finish or sandblasted black or silver it should match any frame colour without too much issue.

Once on the bike it is actually quite subtle unless you really pay attention to it - we've placed on both oversized carbon tubes and skinny steel ones and it suits them all.

Thankfully the Bird Cage isn't just a bit of bike bling; it actually performs as well. Whether you're using a 500 or 750ml bottle the grip remains tight both full and empty so you shouldn't see your bottle disappearing off down the road. Even on a harsh aluminium test bike there was very little in the way of rattling through road buzz and engaging and disengaging is relatively easy to.

Weight wise it is heavy compared to most bottle cages, especially carbon ones but 57g isn't exactly going to effect your climbing ability.

Price is £15 for the chrome and £13 for the sandblasted versions which is pretty damn good I reckon. That price includes two stainless steel bolts as well.

Even after hundreds of bottle movements it's showing no signs of wear and still holding with a vice like grip.

With 20 years of road cycling and over 150,000 miles in his legs it's safe to say Stu is happiest when on the bike whatever the weather. Since writing his first review for back in 2009 he has also had a career in engineering including 3D-CAD design and product development, so has a real passion for all of the latest technology coming through in the industry but is also a sucker for a classic steel frame, skinny tyres, rim brakes and a damn good paintjob.
His fascination with gravel bikes is getting out of control too!
