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.

The Topeak Feza Cage Tubular Carbon R10 is a very light and capable bottle cage that holds bottles well, but it does require a little more force than others to get them out – and it comes with a heavyweight price tag.

One thing is for certain with this bottle cage – it won't weigh you down.

That is because it hits the scales at only 12g. To put that into context, this is the same weight as a £2 coin. That 12g even includes a 'bottle glide', which is a small piece of plastic that sits between the cage and the bolt holes to allow the bottle to slide in more easily. Take that out and you're down to a virtually imperceptible 10g.

That is, from my research, the lightest bottle cage we have tested on – impressive.

One of the main reasons for this low weight is that there is not much to the cage. Its tubular construction resembles aluminium bottle cages from the 1980s, but it's made from carbon fibre, which is considerably lighter.

During my first couple of rides with the bottle cage I was worried that I would accidentally snap it because it doesn't look particularly robust, but after dozens of rides I didn't find any issues at all. I don't tend to be somebody who aggressively wrestles my bottles out of their cage, but even so, I didn't find anything to complain about in terms of potential points of weakness through regular use.

It doesn't have the kind of side entrance/removal that you often find on modern bottle cages, which means it won't be particularly good on smaller frames or bikes laden with frame bags, but for my 56cm road bike there were no issues. This is because this cage is exclusively top entry, so if you've got a larger bottle then you'll need the space above it to remove the bottle easily.

One thing to note about the cage is that it holds bottles very well and there's very little movement even over rougher surfaces. Even when I was using particularly tall bottles there wasn't any excess movement. This comes at a slight price though, which is that the hold on the bottle means you need a little more force to remove the bottle than you would with some cages. That said, it isn't like lifting you're Thor's hammer and it didn't ever feel like I needed to really yank on it, just that it requires a little more effort than on other cages I've used.

Fitting it is just a case of either using your bike's frame bolts or the black T20 Torx bolts that come with the cage, which sit in recessed holes in the cage. You can also install the bottle glide, which sits between the cage and the frame and allows the bottle to slide into the cage more easily.

The RRP is £60, which is steep for any bottle cage. However, given that this is the lightest cage we've tested, some may feel it's a cost worth paying. It certainly won't be something you'd stick on a commuter bike but may be ideal for a money-no-object weight weenie.


You could compare it to the Specialized S-Works Carbon Rib Cage III that Liam reviewed, which comes in £10 dearer and is double the weight – yes, a whole 24g! 

If you're looking for a similar-looking 'retro' bottle cage, then you could splash £90 on Silca's Sicuro Cerakote Titanium bottle cage that Hollis liked, which is titanium so should prove durable – but it weighs 21g more than the Feza.

Overall – I like this bottle cage, it looks great with a minimalist retro look, it weighs less than a £2 coin, and it grips bottles well. The hold on the bottle means slightly more force is required to get the bottle out and there is also the small issue of that £60 price tag...

As far a sales are concerned these copies from Topeak and other, cheaper ones on eBay etc. are a non issue, really.
I can surely understand that it doesn't feel nice when others take your design and run with it, but with the enormous price difference CarbonWorks won't lose a single sale on them. People who buy 25 dollar eBay knock off's, or even the 60 dollar Topeak one, would simply otherwise never have bought the original as it is too expensive for them, and people buying the original have the money to spend and want the real deal.
It's a sucky thing to do from Topeak, but it won't hurt CarbonWorks at all.

Nice cage, but Tune claims 9 grams for their H2O cage

They claim it, but the all in weight of this cage with bolts (I have 4 of them) is between 14 and 15 grams.  I don't have the Topeak cage advertised, but the Carbonworks cage is 8g with bolts.  All very silly and irrelevant of course, but the Tune cage is definitely heavier.  The carbonworks cage also has better retention.

Oh wow, it seems Topeak took a a very close look at carbonworks bottle cage… not a very kind move from Topeak

Very similar designs! These ultralight cages all seem to have a missing direct connection between the two mounting bolts. I had a (much cheaper) cage with this feature, and flex in the cage caused the top and bottom parts to rotate around the bolts. I binned it and went back to one with about 2g more weight that kept its  integrity. 

Dadams7378 replied to MatzeLoCal | 1 year ago

Yes.  It's a blatant copy.  I know that carbonworks are concerned this will possibly put them out of business, as though expensive, its still a lot less than the CW cage.  Cheap Ali Express copies that don't really work are one thing, but this will be at least as 'good', plus cheaper.  Not very ethical as you say.

Blackthorne replied to Dadams7378 | 1 year ago

I don't know about this. It's not exactly a Swiss watch of mechanical complexity. It's less design copying than it is the minimum structural material remaining where there's none left to take away. And if carbonworks is hedging its entire future on a 5gram twig of carbon that costs more than a flight to Italy then I don't see why a company should be discouraged from offering something more competitive.

I think the issue is that Topeak know exactly what they were doing as carbonworks is essentially a one-man band. It's not just Topeak's design is similar, they are actually banned from selling the product in Germany as it infringes on his copyright. Unfortunately as a smaller operation he couldn't afford the legal fees/copyright for all territories

Dadams7378 replied to Blackthorne | 1 year ago

It's very cynical from Topeak IMO.  Carbonworks came up with a great looking design that managed to stand out from the crowd and remained functional whilst being materially lighter than anything else out there.  It proved very popular for this reason, and Topeak have just seen some easy sales and copied it, relying on their much better financial position and the probability that carbonworks would not have the financial ability to enter into a legal battle.  I very much doubt they would have done the same if the original design had been created by Specialized for example.  Perhaps carbonworks haven't done all they could / should have in terms of putting in place legal protections for their design (I've no idea whether this is true or not), but it still leaves a bad taste in the mouth.
