Genuine Innovations Ultraflate Plus — Specs & Analysis
Manufacturer specifications, compared against every other tools & repair in our database. We do not test gear in the field — we measure, verify, and compare.
The Genuine Innovations Ultraflate Plus is a compact CO2 inflator with a precision control valve that prevents wasted cartridges. It accepts both threaded and non-threaded 16g CO2 cartridges for quick roadside inflation.
The Genuine Innovations Ultraflate Plus solves the biggest complaint about CO2 inflators: wasted cartridges from uncontrolled gas release. Its precision push-to-inflate valve lets you meter the gas flow, so you can partially fill a tire, check the bead seat, and then add more air — all from a single cartridge.
The head features a dual Presta and Schrader chuck that threads securely onto either valve type without an adapter. This universal compatibility is valuable for bikepackers who may encounter different valve types on touring bikes, mountain bikes, or borrowed wheels during a multi-day ride.
At just 55 grams without a cartridge, the Ultraflate Plus is significantly lighter than any mini pump and takes up a fraction of the space. A 16g cartridge fills a 700x40c tire to roughly 45 PSI or a 29x2.2 mountain tire to about 25 PSI — enough to get you rolling again quickly.
The padded sleeve that ships with the inflator serves double duty: it insulates your hand from the extreme cold of expanding CO2 and provides a better grip during inflation. This is a small detail that makes a meaningful difference when you are fixing a flat with cold or wet hands.
The obvious limitation is that CO2 inflators are consumable — once your cartridges are spent, you need a pump or more cartridges. Most bikepackers carry two cartridges and a lightweight backup pump for extended trips. For shorter rides and races, the Ultraflate Plus alone is sufficient.
For bikepackers who prioritize speed, simplicity, and weight savings in their flat repair kit, the Ultraflate Plus is the gold standard in controlled CO2 inflation.
Who Is the Genuine Innovations Ultraflate Plus Best For?
Bikepackers who want the fastest, lightest flat repair option for races and shorter routes. If that describes your riding style, the Ultraflate Plus should be at the top of your shortlist. It sits in the Tools & Repair category alongside 15 other products we track.
How It Compares
At 55g and $20, the Ultraflate Plus is 29g heavier than the lightest option in this category (the Dynaplug Racer Pro Tubeless Repair at 26g). The most budget-friendly option is the Pedro's Tire Levers (Pair) at $6.
The price-to-weight ratio comes in at $36 per 100g — a premium price point, but you're paying for quality, materials, and design that justify the investment for serious bikepackers.
What We Like
- +Precision valve prevents wasting CO2 cartridges
- +Universal Presta and Schrader compatibility
- +Extremely light and compact
- +Insulated sleeve protects hands from cold

The Bottom Line
We haven't scored the Genuine Innovations Ultraflate Plus, 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: 55g, $20, and how both sit against every other tools & repair 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
Genuine Innovations publishes a packed size of 11 x 3.5 x 3 cm, which is 0.1 litres as a folded block. Of the 55 bags we track that publish a capacity, 55 have room for it and 0 do not.
Volume is computed from Genuine Innovations'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 it compares
Against the 16 tools & repair products we hold published specs for.
At 55g the Ultraflate Plus is lighter than 11 of 15 alternatives we track. The category median is 108g.
At $20 it undercuts 13 of 15 of them, against a median of $35. That works out at $36 per 100g — above the $36 median for tools & repair products.
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.
