Meet the HydroMount: the tiny yet versatile mount that lets riders run water bottles, cargo cages and more, anywhere on their bike frame – with no bottle bosses required.
With a retail price of just £20 (2-strap Base version) and £25 (3-strap Full version), the HydroMount marks Tailfin’s most accessible product to date, opening the brand to everyday riders, commuters, gravel riders and bikepackers alike.
HydroMount solves a simple but widespread problem: not enough bottle cage mounts, especially on small frames, older bikes, full-suspension frames, and heavily loaded gravel or bikepacking setups. Where many strap-on solutions look improvised, unstable and risk damaging frames, HydroMount builds on proven V-Mount technology to deliver a clean, purpose-built alternative that looks, and performs, like part of the bike.
The Tailfin HydroMount Need To Know:
- Load capacity:
- 1kg with 2 straps
- 1.5kg with 3 straps
- Standard 64mm bottle cage mounting holes, compatible with most cages and the Tailfin Mini Cage
- Overmoulded rubber body for built-in frame protection
- Integrated moulded threaded inserts for long-term durability
- Bolt set with bottom-out protection
- Tool-free adjustment
- Tiny enough to stash in a tool roll when not in use
- Supplied with straps as standard
Unlike webbing straps, DIY cargo strap-style solutions, or generic mounts, HydroMount combines material innovation, structural integrity and aesthetics in one integrated design.
Key differentiator: this is the only solution that combines overmoulded rubber protection, integrated threaded inserts, and a design that looks native to the bike. It’s not “make do” – it’s designed. It also has the lowest stack height of any similar style accessory mount.
Construction & Design Highlights
At its core, the HydroMount features our unique and proven V-Mount design, as found on all our existing Top Tube and Frame Bags, to offer absolute security with zero slip when fitted. The V-Mount’s specific shape and soft TPE (Thermoplastic Elastomer) rubber overmoulding are designed to work on all frame tube profiles and to completely protect delicate materials and finishes from damage.
From Bottles to Pickle Jars
HydroMount’s core purpose is to increase the hydration capacity of your bike’s setup. Ideal when running frame bags or other setups that can compromise standard water carrying.
From bottles to tools and cook kits, the HydroMount embraces the idea that if it fits in a cage, it can go on your bike.
HydroMount represents a shift in accessibility for Tailfin. While the brand is known for premium rear racks and bikepacking systems, this is a product for any rider who occasionally needs to carry more:
- Riders with small frames
- Owners of older bikes with limited mounts
- Gravel riders and bikepackers needing extra hydration on long days
- Commuters and everyday riders who just want more flexibility
If you ride a bike, there will be a day when you wish you had one more place to put a bottle. HydroMount is for that day.
