NorthCape4000: bags—capacity, weight, aero

For NorthCape4000 2026 (from Berlin, about 3,000 km), how you carry gear matters as much as how much. The setup overview lists what I am taking; this piece is about mixing brands, shape, and aero—and checking fit with paper templates so I do not have to haul a fully built bike into a shop.

The idea: smart capacity-to-weight ratio

I deliberately picked bags from more than one maker. The aim was the best trade-off of volume to weight—not a matched kit for the photos, but per position the option that fits the frame, cockpit, and how I ride.

Set at a glance (empty, sum of manufacturer specs): Cyclite aero bag up front, Apidura top-tube and frame bags, Cyclite saddle pack 12.9 L — 916 g total weight, 24.8 L capacity.

Top-tube bag: slim and tapering—no knee rub

For the top-tube bag I optimised width and outline: as narrow as possible, tapering a bit toward the top, so my knees do not scuff it every stroke—while still getting useful volume. I chose Apidura Racing Long Top Tube Pack (2 L, 210 g, about 44 × 4.5 × 10 cm) for cockpit bits (snacks, lip balm, phone …).

Frame bag: maximum volume, minimum weight

Same priorities for the frame bag: lots of space for low weight, low in the triangle so heavy items do not lift the centre of gravity. What goes in there (including the Nitecore and tools) is also covered in power, lights & energy budget. I settled on Apidura Expedition Frame Tall (5 L, 180 g, about 47 × 6 × 14 cm): on my size 56 Roadmachine it fits perfectly. Templates from Cyclite and Apidura on the frame surface clashes with bottles or cables before you order.

With a frame bag, bottles must come out sideways—the stock BMC downtube cages do not allow that. I use BMC’s Downtube Storage Cover Roadmachine (cover with mounts for standard bottle cages). On it I run height-adjustable Blackburn cages: one releases to the left, one to the right, so after fitting I pull both bottles the same way. More on the frame: bike & cockpit.

Saddle pack: from the big Ortlieb to Cyclite 12.9 L

The saddle pack was not a quick call either. The big Ortlieb from Iceland and larger Apidura saddle packs would have been too bulky and heavy for this trip. Cyclite Saddle Bag / 01 (12.9 L, 318 g, about 52 × 23 × 18 cm) gives me a practical Garmin Varia mount (rear light with radar), a solid capacity-to-weight ratio, and very little sway—so that version.

Front: Cyclite Handle Bar Aero Bag—no bar roll

Up front I use Cyclite Handle Bar Aero Bag (4.9 L, 208 g, about 23 × 18 × 16 cm). A lighter aero option looked better on paper—shape and secure fit on the extension cockpit mattered more to me. No bar roll across the bars: less frontal area.

Musette, lashing, and what is still open

I also pack Apidura’s tiny ultralight musette (about 7 L)—negligible in the luggage, mountable e.g. under the stem when I need a bit more volume fast. Extra items can still be strapped to the aero cockpit bag or the saddle pack.

Optional: I am still thinking about an ultralight trail running vest—e.g. a 7 L Arc’teryx in hi-vis yellow—for shopping or errands so I can carry loads on my body without repacking the bike. Not decided yet.
