The folded pole set is 445mm, which is the 23rd shortest of the 29 shelters we hold a pole length for. At 964g it is 20th lightest of 37.
On the two weights. The 936g at the top of this page is the figure we hold on the product record. Big Agnes also publish a minimum (trail) weight of 964g and a packed weight of 1080g. Minimum weight leaves out stakes, guys and the stuff sack; packed weight is everything in the bag. We show all three rather than picking one and calling it “the” weight.
Beyond the usable span on drop bars. Carry it on the frame, in a seat pack, or strapped to a fork cage instead. This figure is the packed bag's long dimension, not a pole length the maker publishes — for this style of tent the two are the same thing, but measure before you commit.
Comfortably inside the usable span on flat bars, with room for cables and a harness. This figure is the packed bag's long dimension, not a pole length the maker publishes — for this style of tent the two are the same thing, but measure before you commit.
3 shelters here are both shorter-poled and lighter: Nordisk Lofoten 1 ULW (220mm, 490g), NEMO Hornet OSMO Ultralight 1P (320mm, 822g), Big Agnes Tiger Wall UL1 (430mm, 822g). Anything not on that list is a trade rather than a straight win.
Only 29 of the 43 shelters we track publish a figure we can compare, which is why this question is so hard to answer anywhere else. The figure above is the packed bag's long dimension rather than a pole length the maker publishes — for this style of tent the two are the same thing, but measure before you commit.

The Copper Spur is the gold standard for ultralight solo tents. The high-volume hubbed pole design creates surprisingly livable interior space for a sub-1kg tent. The bikepacking-specific version distributes into three stuff sacks that fit in a handlebar roll.
If there's one tent that has earned "default recommendation" status in the bikepacking community, it's the Big Agnes Copper Spur HV UL1. It's not the lightest, not the cheapest, and not the most heavily built — but it hits the sweet spot of livability, weight, and packability that makes it the right choice for the widest range of bikepackers.
The "HV" stands for High Volume, and you feel it immediately when you crawl inside. The hubbed pole design pushes the tent walls outward, creating steep sidewalls that give you genuine sitting-up room. Compared to narrow tapered tents like the Nemo Hornet, the Copper Spur feels like a palace. For riders over 5'10", this extra volume is the difference between tolerating your shelter and actually being comfortable in it.
Big Agnes made a brilliant decision with the bikepacking-specific version: it splits into three separate stuff sacks. The tent body, fly, and poles each get their own sack, so you can distribute them across your handlebar roll, frame bag, and seat bag. This solves one of the biggest problems with carrying a tent while bikepacking — you don't need one huge stuff sack that only fits in one location.
Setup is fast and intuitive. The color-coded clips snap onto the hubbed pole structure in seconds. The colour-coded, hubbed pole structure is designed for fast pitching, including in poor light. The two-door, two-vestibule design means you can stash muddy shoes and cooking gear in the vestibule without blocking your entry.
The 936g weight puts it in the ultralight category without resorting to the extreme fabric choices (like Dyneema) that push prices toward $600-800. You're getting a fully featured double-wall tent — inner mesh body plus waterproof fly — which means excellent condensation management compared to single-wall alternatives.
The trade-offs are real, though. At $400, this is a serious investment. The fabric is thin — you need to clear your campsite of sharp objects, and a stray branch can punch through. And while the tent has a freestanding pole structure, it really needs stakes to achieve the proper pitch, especially in wind. Carry at least six stakes and you'll be fine.
For bikepackers doing multi-day routes in three-season conditions — which is the vast majority of bikepacking trips — the Copper Spur HV UL1 remains our top tent recommendation.
Who Is the Big Agnes Copper Spur HV UL1 Best For?
Ultralight bikepackers who want a real tent, not a tarp. If that describes your riding style, the Copper Spur HV UL1 should be at the top of your shortlist. It sits in the Shelters & Tents category alongside 17 other products we track.
How It Compares

The price-to-weight ratio comes in at $53 per 100g — a premium price point, but you're paying for quality, materials, and design that justify the investment for serious bikepackers.

The Bottom Line
We haven't scored the Big Agnes Copper Spur HV UL1, and neither has anyone else we can cite. It's here for its verified specifications and dimensions, which is what the fit tools run on — a score is an editorial judgement, and we don't hand one out until someone has a basis for it. What this page can tell you is measured: 936g, $500, and how both sit against every other shelters & tents product we track.

Specifications and dimensions come from the sources listed above. Where a page draws on first-hand riding, it says so.
What it packs down to
Big Agnes publishes a packed size of 4" x 19", which is 3.9 litres as a stuff sack. Of the 55 bags we track that publish a capacity, 36 have room for it and 19 do not.
Volume is computed from Big Agnes's own packed size, treating a two-dimension figure as a stuff sack. Bag capacities are the makers' published figures, not ours — 12 of the bags we hold dimensions for publish no capacity and are left out of the count rather than assumed. A stuff sack does not reshape itself, so read the headroom as room to spare rather than a guarantee it goes in easily.
How the Copper Spur HV UL1 compares
Against the bags people cross-shop it with, measured rather than reviewed — including how many real frames each one fits.
How it compares
Against the 18 shelters & tents we hold published specs for.
At 936g the Copper Spur HV UL1 is lighter than 5 of 17 alternatives we track. The category median is 822g.
At $500 it undercuts 5 of 17 of them, against a median of $360. That works out at $53 per 100g — above the $50 median for shelters & tents.
Weight and price come from published specifications. Cost per 100g is a blunt measure — it rewards light gear and says nothing about durability or whether the thing works — so treat it as one input, not a verdict.
