For February we’ve got statement new aero bibs, top end new gravel/MTB shoes from Italian masters Sidi, the return of a triathlon giant to our stores and a perfect marriage of practicality and style.
There are two very different things to say about the latest edition of Castelli’s updated performance favourite. Firstly Castelli has found even more free speed for its riders. A CdA reduction of 3% is achieved through a combination of Castelli’s Forza2 stretch fabric, ingenious seam placement, and aero optimisation features across the rider’s legs. Combined with the top-of-the-line features we expect from Castelli’s Rosso Corsa racing series, it’s everything a fast rider could want from their bib shorts.
The other thing to say is—have you seen the all-white version? Now we’re talking! Imagine winning a town sign sprint in those… What a statement. Certainly, they’ll need to be saved for summer best, but on those days, with your warm weather fitness at its height—well, you’ll feel like the Mathieu van der Poel of the Epping Forest club run.

Sidi has adapted its Grand Tour–winning Shot 2 road shoes for the rough demands of MTB racing and gravel riding. An off-road–specific, reinforced carbon outsole offers outstanding vibration damping and exceptional rigidity, sending every watt straight to the pedals. The Tiger 2S makes full use of Sidi’s renowned construction and materials, tailored for the world beyond the road.
The upper is crafted from high-grade BioVeg microfibre, which moulds to your feet over initial use, delivering a personalised fit. Integrated toe protectors fend off hidden rocks and roots, while a centrally positioned dual fastening closure system stays out of harm’s way and ensures aerodynamic efficiency.

We’re delighted to welcome HUUB back to Sigma Sports. The best word to describe HUUB’s performance-focused triathlon kit is honed—honed by science, engineering, fluid dynamics, CFD analysis, and class-leading expertise; honed by the experiences, feedback, and guidance of the elite athletes they work with; and honed by an ethos of continuous improvement, ensuring each new wetsuit, trisuit, swimwear design, and aero accessory outperforms what came before.
HUUB’s 2025 range at Sigma Sports includes their record-breaking Anemoi Trisuit, the unprecedentedly flexible Pinnacle wetsuit, plus Aerobridge base layers, aero calf sleeves, goggles, trunks, and optimised saddle and top tube bags for race day.
ASSOS and ORTLIEB have joined forces, combining ASSOS’ elegant design with ORTLIEB’s resolutely practical construction. The frame, handlebar, and seat packs provide the utilitarian storage needed for a well-considered bikepacking setup while adding an eye-catching complement to your frame.
Most intriguing for us at Sigma Sports is the ASSOS x ORTLIEB Atrack Backpack. ORTLIEB’s Atrack is an IP67-rated waterproof pack with a unique full-length zip that opens from the back, allowing easy access to your kit without the rummaging required by top loaders. Optimised for cyclists, the removal of hip wings ensures unrestricted movement in the saddle, while the adjustable length lets your hips anchor the load instead of straining your back. Thoughtful additions—including a helmet enclosure, a hydration bladder compartment, and breathable straps—mean you’ll never have to wonder if a hiking rucksack will work for your riding adventures again.

The MET Drone Wide Body helmet shows just how far time triallists and triathletes can go in their quest for aerodynamic advantage. Rather than streamlining only the head, it also tackles turbulence around the shoulders. At typical flat TT speeds of around 50km/h, this design can save a race-altering 10 watts.
Although aerodynamics is paramount, safety and comfort remain key considerations. The wide shell maximises the effectiveness of the helmet vents improving airflow of hot air out through a large exhaust. An in-mould polycarbonate shell with an EPS liner absorbs and disperses impacts, helping protect your head in the event of a crash.
