    Custom Frame Bag

    Out of stock

    Looking to get started with a new frame bag? You're in the right place. With strong X-Pac VX21 and Cordura fabrics, beefy YKK water-repellent zippers, and hypalon-reinforced attachments, these frame bags are in it for the long haul with you.

    Our custom frame bags are built to the specifications of your frame. We'll need measurements of your specific bicycle—see details here—and then we'll put together a bag to match. We build our frame bags to be 65mm wide throughout, tapering in a bit at the bottom bracket to avoid tearing from the chain. 

    You have a few options to think on as you're planning your frame bag. These range from additional zips (ideal for larger frames) to flared out fronts of the frame bags (ideal for those looking to maximize storage space). 
    Colors:  Black / White / Red / Grey

    All of our frame bags start out with a single #10 YKK Urethane-coated water repellent zipper; a beast of zipper, settle for less at your peril. If you're riding a particularly large bike--generally appropriate with a top tube length > 520mm--we'd recommend going for an additional zippered compartment towards the base of the frame bag to keep your gear a little more organized. Velcro flaps keep this compartment separate from the main storage space, and can be folded down when the second compartment isn't wanted. Further zipper options include making a map pocket on the non-driveside of the frame bag.

    We use the slightly smaller #8 zips for additional zippers, as these compartments generally won't see as much abuse as the main zip.

    Zippers are a great, convenient way to open a frame bag, but even the best of them need to be taken care of. After muddy or dusty rides, wipe down the zipper with a wet cloth to prolong its lifespan.

    Flared fronts:
    For riders looking to maximize their storage space, choose this option. We'll modify the front of your frame bag to widen from a width of 65mm to 120mm at the head tube. We'd say this is a bit unnecessary on road bike frames-- road bike geometries tend to be more spacious than their mountain bike compadres. But on a semi-fat or full fat bike? Fatten it up!

    Front Accessory Bag

    An ‘add on’ to the front system, boosting storage capacity and allowing easy access to the stuff you’ll need during the day. 

     The design differs fundamentally from everything else out there. We wanted to make something completely waterproof, with a good-sized carrying capacity, yet super stable over the rough stuff.  It wasn’t easy, but doing things differently never is. Here’s why it rocks:

     Fully Waterproof

  4. Stitched construction and zippers as used on other bags won’t fully protect your gear from getting wet in a downpour. Not a disaster, you just use dry bags, but this adds faff. We wanted a bag we could simply throw a camera, lenses, phone, notebook, extra layer and a Buff or two into, pack it out efficiently, quickly grab stuff when needed and not worry about anything getting damp, whether it be a river crossing or a Patagonian deluge.
  5. Our system uses a heat-sealed waterproof liner, which sits inside a tough XPac and Cordura exterior. The bag also has a roll top style closure with a Hypalon reinforced cover flap. Belt and braces peace of mind to protect your mission critical gear.
  6.  Zipperless Construction

  7. For a bag which see’s a lot of opening and closing, zipper failure will always be it’s Achilles heel, ask any expedition bikepacker.  No zipper = No worries.
  8. Size & Stability

  9. There’s nothing more frustrating than a bouncing front bag, but likewise you don’t something so small to be pointless. We think we’ve hit the sweet spot, providing a useful 5 litres of capacity and adopting a curved profile so that it’s a snug fit against the front dry bag, making for a very stable system.
  10. Harness Integration

  11. Designed to clip into the Harness, with straps able to be adjusted from both the top and bottom, you can really tension this thing on and be confident that it’ll stay in position no matter what you throw at it.
  12. It can also be used with other harnesses via our Bar Connector Straps

    Front Harness

    Out of stock


    Our front harness allows you to mount a 10-20L dry bag or other cylindrical shaped load below the handlebar, and is great for stashing bulky gear like sleeping bags, sleeping pads and tents. This versatility, large capacity and ability to pack/unpack away from the bike makes it a must have for on any multi-day bike adventure. 

    Our design has taken considerable time and testing to perfect, and after countless prototypes we reckon we’ve nailed it. Here’s why:

  • Bombproof Construction.  We use a 4-layer laminate to provide rigidity and durability, with: XPac VX21 outer fabric; HDPE plastic sheet, a lightweight foam insert and Cordura 500d inner fabric. Hypalon reinforcement is also used for possible contact areas; along the handlebar and head tube zones.  Duraflex buckles used throughout.
  • Optimised Geometry. A tapered design is used to ensure that there’s support where it’s required, but any ‘extra fat’ is trimmed off to save weight.  
  • Rock Solid Attachment System. The harness attaches securely to the bars via custom made plastic blocks using a dual attachment system; first it’s secured using Velcro straps and then with webbing straps passed through Duraflex TensionLock® buckles. Combined with the head tube connection strap, it achieves bombproof stability with no loosening off (even after the most demanding of Andean singletrack descents…!).
  • Cable & Lever Clearance. Common issues with harnesses on mountain bike bars are cables being ‘squashed’ and levers digging into the bag. To alleviate these problems the harness is offset from the handlebars via the custom made plastic blocks, protecting both bike and bag.  (Note: On road bars it is possible to strip down the harness and not use the blocks, to save weight and increase tyre clearance)
  • Riser Bars? No Problem.  The plastic blocks are also designed to allow the curved profile of riser bars to be easily accommodated, without bending the harness. The blocks feature channels, allowing the Velcro connection straps to grip tight and ensure that everything remains locked together, even for bars with a high rise angle.
  • 3 Strap System. We feel it’s essential to use 3 straps, rather than just 2, to connect the bag. Advantages include: ease of attachment (balance the bag by connecting the central strap first), preventing sag over the tyre zone and possible rubbing and allowing larger bags to be accommodated. (Note: The outer straps are moderately spaced at 17cm (centre to centre) such that smaller bags can also be used for road bikes without the risk of the straps sliding off the edges)
  • Head Tube Protector. A dense closed cell foam block is incorporated into the head tube connection strap to alleviate harness rub against paintwork/cables.
  • Integrated Front Accessory Bag Straps. The Front Accessory Bag can attach directly into the harness. The top connection straps are adjustable and feature Duraflex CamLok buckles, with Velcro Onewrap ‘strap keepers’ to stow the excess strap when not in use.

    Partial Frame Bag

    Out of stock

    Our 1/2 sized frame bags are ideal for road cyclists, mountain bikers riding large frames, or for those who simply want to take advantage of more gear space while still using water bottles. Maybe you're a commuter looking for a more stream-lined way to carry a change of clothes? 1/2 frame bags could be your friend.

    Our 1/2 frame bags are available in 3 different stock sizes. Based on a rigorous analysis of bike frames and geometries, we came up with 3 different geometries that conform well to a wide range of different bikes. All of the bags use cam-lock straps around the seat tube, head tube, and down tube to ensure a sturdy fit on different size bikes.
    Alpamayo Designs Half Frame Bag Sizing Analysis

    These 1/2 frame bags are constructed to the same high quality and water-resistant standards as our full-size frame bags, with VX21 & 1000D Cordura sides and a #8 YKK Urethane coated, water repellent zipper.

    1/2 Frame Bag Size Details:

    Inside top tube lengths:

    Size #1: 480mm
    Size #2: 495mm
    Size #3: 535mm

    Size #1 corresponds to a small to medium mountain or road bike, Size #2 to a medium to large mountain bike, or a medium to large road bike. Size #3 will generally only fit well on very large road bikes, but check the length of your bike's top tube to compare.

    For proper fit, choose the size closest to, but not longer than, your bike's inside top tube length. So say your bike has an inside top tube length of 470mm - you'd want Size #1. Or if your bike's inside top tube length is 486mm - well, you'd still be best going for a Size #1, and the adjustable straps will take up the slack. But for an inside top tube length of 525mm, you'd be best suited with a Size #2, instead of getting the closer fitting Size #3 that will need to be squished in to fit.

    Seat Pack

    A key component of any bikepacker’s luggage arsenal. When we started designing the seat system we set out to overcome our two biggest frustrations with conventional seatpacks; minimising ‘tailwag’ (side to side wobbling) and having an easily removable bag for packing/unpacking away from the bike.After countless iterations and months of testing we arrived upon a semi-rigid harness with a tapered Xpac VX21 bag. As usual though, the devil is very much in the detail:

    The Harness

  • Keen to avoid rigid metal connections, the base of the harness draws its stiffness from an HDPE plastic/500d Cordura laminate, reinforced with an aluminum 'spine'.
  • An elasticated cargo net also features, useful for stowing lightweight shoes or other awkward items
  • The upper part of the harness comprises side panels of high-density foam and Cordura 1000d/500d, with a full Hypalon central panel, providing incredible abrasion resistance to all contact points. 
  • Unique Saddle Rail Connection 

  • This features a high-density foam strip to securely seat the rails, with independent Velcro straps to keep them in place. This effectively eliminates sideways movement of the harness relative to the saddle rails.
  • The upper part of the harness in the saddle connection zone is stiffened via a profiled aluminium section sewn into the fabric. This ‘clasps’ both sides of the bag significantly reducing any lateral swaying of the bag (or ‘tail wag’) 
  • No Compromise Side Strap Tensioning 

  • The stability of any seat system is only as good as the tensioning of its side straps, and some strap slippage is inevitable with a standard side release buckle when ridden hard off-road. We’ve therefore taken a ‘belt and braces’ approach, passing the straps through both ladderlocks and cam-lock secured side release buckles.
  •   The Bag 

  • Full Xpac VX21 construction; highly abrasion resistant, ripstop, and incredibly waterproof.
  • Geometry tailored for the harness to provide maximum storage space and stability through a ‘snug fit’
  • Please note that, while the fabric is waterproof, there is the possibility for water to enter through the seams when exposed to heavy, sustained rain. We therefore recommend using an internal dry bag for contents that must remain absolutely dry (e.g. electronics).

    Whether you're out on an endless endurance ride or a short jaunt around town, Stem Bags provide easy access storage for all of your favorite gear. These 1L bags mount to a bike's handlebars, stem, and fork crown; 3 points of attachment mean they're not going anywhere. Got a bag of nuts? Candy? Nalgene bottle? These little fellas hold it all. Like all of our products, Stem Bags are made from a mix of Cordura and sailcloth fabrics. Mesh pockets on each side leave a place for empty (candy) bar wrappers, too.

  • VX21 sailcloth / 1000D Cordura construction
  • Two mesh pockets reinforced with seam tape; enough stretch without elastic that will weaken
  • One-handed top opening
  • 100g, +/- 10. 

  • *Note: Some particularly tall riders report interference between their knees and similarly mounted handlebar bags when riding out-of-the-saddle. Sorry guys. There's gotta be some balance to your advantages of having such long legs. Us small frame people suffer in our own ways.
