At road.cc 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.What the road.cc scores mean
Good scores are more common than bad, because fortunately good products are more common than bad.
There are normally three material options when it comes to bottle cages, plastic, carbon fibre or aluminium and it's the latter that GT have chosen for their Corsa cage, 6061-T5 to be precise.
It's a one-piece design, pressed into shape which should mean no weaknesses anywhere or welds to fail over time.
The curved 'arms' provide a good tight fit on both 500 or 750ml bottles and although tight to begin with, making getting your bottle in and out a touch fiddly, they soon relax. They still provide plenty of compression to stop your bottle jettisoning off down the road though. The outer edges are rolled which makes lining your bottle up pretty easy too.
A weight of 47g is about right for an aluminium cage and there are four colour options, black, white, red and silver, all finished in a high gloss paint.
To allow for slight tolerances in frame boss position the bottom fixing hole is actually slotted giving 2mm or so of flexibility.
Priced at £10.99 the Corsa is a decent level bottle cage which thanks to the gloss finish looks more expensive than it really is. The fit on the bottle is good once things have eased and I was that confident in it I even risked sticking a bottle of wine in there for a 5 mile trip back from the shops.
A smart looking bit of finishing kit for your GT bike, or any other for that matter.

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 road.cc 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!
