Rakusogaku Kobo Sekkei Mountain Coffee Dripper | An Ultralight 20g Dripper for a Special Cup Outdoors Make your coffee at the summit lighter, simpler, and more memorable. The Sekkei Mountain Coffee Dripper by Rakusogaku Kobo is a compact, assemble-and-disassemble coffee dripper designed for hiking, camping, bikepacking, and bicycle touring. It weighs only approximately 20g. Its exceptionally low weight makes it easy to add to an ultralight outdoor setup, while the collapsible construction allows it to fit into a small space inside a backpack or bicycle bag. The dripper is handmade using repurposed stainless steel bicycle spokes that would otherwise have been discarded. Its distinctive shape is inspired by snowfields and mountain ridgelines in the Japanese Alps, combining practical outdoor function with a unique upcycled design. To use it, assemble the dripper, place it over a Sierra cup or mug, insert a filter, and slowly pour hot water over the coffee. It is recommended for use with HARIO V60 01 cone-shaped filters and is also compatible with trapezoid filters, cloth filters, and standard single-use drip coffee bags. The raised structure helps prevent a drip coffee bag from becoming submerged in the brewed coffee. The open design also allows gas released during brewing to escape more easily, helping produce a clean and balanced cup. Whether you are starting the morning at a campsite, resting on a mountain summit, or stopping beside a river during a ride, the Sekkei lets you carry the pleasure of freshly brewed coffee without adding unnecessary weight. 【STAFF REVIEW】 The first thing you notice when holding the Sekkei is its remarkably low weight. At approximately 20g, it adds very little to hiking or bikepacking equipment. When disassembled, it fits easily into a small space, and its spoke construction also makes it convenient to hang from a backpack strap. It works well not only for traditional pour-over coffee, but also with standard single-use drip coffee bags. This makes it an approachable choice for anyone who wants to enjoy a simple cup at a summit or campsite. The appearance of the stainless steel gradually changes with use, adding character over time. Its light weight, handmade construction, and upcycled background make it a piece of equipment that is easy to appreciate and enjoy for many journeys. 【FEATURES】 ・Ultralight single-cup coffee dripper weighing approximately 20g ・Compact construction that can be assembled and disassembled ・Made from repurposed stainless steel bicycle spokes ・Original design inspired by alpine snowfields and mountain ridgelines ・Open structure allows gas to escape easily during brewing ・Compatible with Sierra cups and mugs with openings up to 9.5cm in diameter ・Suitable for cone filters, trapezoid filters, cloth filters, and drip coffee bags ・Ideal for hiking, camping, bikepacking, and bicycle touring ・Individually handmade 【SPEC】 Product: Sekkei Mountain Coffee Dripper, Single-Cup Size Brand: Rakusogaku Kobo Weight: Approx. 20g Height: Approx. 6cm Diameter: Approx. 9.5cm Material: SUS304L Stainless Steel Recommended Filter: HARIO V60 01, 1?2 Cup Size Compatible Cups: Sierra cups and mugs with openings up to 9.5cm in diameter Production: Handmade 【PLEASE CHECK BEFORE USE】 Compatibility and stability may vary depending on the shape and rim thickness of the cup.

Rakusogaku Kobo UKIBI Ultralight Fire Pit | A Handmade Upcycled Fire Pit Light Enough to Float Giving discarded bicycle spokes a new purpose. The UKIBI is an ultralight fire pit handmade by Rakusogaku Kobo using old-standard bicycle spokes that would otherwise no longer be used. It weighs approximately 65g in the Mini size and only 95g in the Medium size. Light enough to float on water, it is an ideal choice for ultralight hiking, bikepacking, bicycle touring, and solo camping, where every gram of equipment matters. Its distinctive structure is made by carefully assembling thin bicycle spokes. Despite its exceptionally low weight, it provides enough strength to support a practical campfire setup. After use, the fire pit packs down into a thin, compact shape that can be stored in a small space inside a backpack or bicycle bag. When combined with household aluminum foil, its design helps create a three-layer barrier against radiant heat reaching the ground. More than simply a lightweight piece of equipment, the UKIBI represents an upcycling approach that transforms unused bicycle components into a functional outdoor tool. Its simple construction reflects thoughtful craftsmanship and carries the story of the materials from which it was made. For travelers who want to reduce the weight of their equipment without giving up the experience of sitting around a fire, the UKIBI offers a compact, practical, and highly distinctive solution. 【STAFF REVIEW】 The first thing you notice when holding the UKIBI is just how surprisingly light it feels. In ultralight hiking and bikepacking, even a difference of a few dozen grams can have a meaningful effect on the overall weight of your equipment. The UKIBI perfectly represents this lightweight approach. It takes up very little space in a backpack or bicycle bag, while still allowing you to enjoy a real campfire at your destination. Its appeal also goes beyond its low weight. The use of repurposed bicycle spokes and the fact that every unit is made entirely by hand give the fire pit a story and character of its own. It is highly recommended for those who value not only functionality, but also thoughtful craftsmanship, upcycling, and the background behind the equipment they choose. 【FEATURES】 ・Upcycled fire pit made from old-standard bicycle spokes ・Approximately 65g for the Mini size and 95g for the Medium size ・Ideal for ultralight hiking, bikepacking, and bicycle touring ・Entirely handmade without automated production ・Maximum load capacity of approximately 3.5kg ・Designed for use with household aluminum foil to help create a three-layer radiant heat barrier ・Thin and compact when packed ・Suitable for solo camping and bushcraft 【SPEC】 〈Mini / Size S〉 Weight: Approx. 65g Maximum Load: Approx. 3.5kg Dimensions in Use: Approx. 21 × 21cm Height: Approx. 9cm Material: Stainless Steel Spokes Packed Size: Approx. 29 × 22cm Included: Storage Case 〈Medium / Size M〉 Weight: Approx. 95g Maximum Load: Approx. 3.5kg Dimensions in Use: Approx. 27 × 27cm Height: Approx. 11cm Material: 2.0mm Stainless Steel Spokes, with some brass and aluminum components Packed Size: Approx. 38 × 28cm Included: Storage Case Production: Entirely Handmade Recommended Use: Solo Camping / Bushcraft / Ultralight Hiking / Bikepacking 【PLEASE NOTE】 As each fire pit is made by hand, there may be slight variations in shape and finish. Please check the fire regulations and rules of the campsite or area before use. Use a fireproof ground sheet, aluminum foil, or other suitable heat protection when necessary. The fire pit becomes extremely hot during and immediately after use. Handle it carefully and take all necessary precautions to prevent burns, fire, or damage to the surrounding ground. ▼日本国内への配送ご希望は以下リンク先よりご購入手続きください。 https://store-eirin-jp.com/products/ukibi-ul-stove
