If there was a Mount Rushmore of racing saddles, the Fizik Arione would surely be present, carved in recognition of its iconic status, for eternity. And now it\u2019s back, reimagined for 2026 and beyond. We take a closer look below.<\/p>\n

It’s not the only saddle featured here. We’ve also got an e-bike friendly perch from another Italian brand, Prologo. We make it a hat-trick for the cycling mad nation with the inclusion of Castelli<\/a>‘s new gravel racing<\/a> gear but give a nod to ol’ Blighty thanks to a rather elegant looking titanium seat post from Sussex heroes, Mason Cycles.<\/p>\n

Fizik Arione returns<\/p>\n

A lot has happened in saddle tech since the Arione first launched in 2003 and the updated Vento models look to take advantage of these developments. There\u2019s a new rail insertion that allows for the aggressive aero positions that today\u2019s top riders like to contort themselves into; to achieve this Fizik has created a vertical join into the saddle so the rider can move it as far forward as possible without limit.<\/p>\n

Naturally there are a couple of Adaptive models, using 3D-printed padding for tailored zonal comfort. Fizik says this accounts for a 60% reduction in peak pressure thanks to improved weight distribution across the entire saddle surface. It\u2019s offered in two models, the R1 and the R3: the former has carbon rails while the latter uses Kium.<\/p>\n

The R1 Light eschews 3D-printed padding for a low-profile injected EVA padding, which it combines with a light shell and a stiff carbon rail. At a claimed 147g for the 135mm width, and 152g for the 145mm width it is more than 30 grams lighter than the R1 adaptive model.<\/p>\n

To ensure that the new Arione is available at a wide range of price points, it\u2019s offered in a \u2018regular\u2019 R3 and R5 model that both employ its signature long, flat profile – 284mm long to be precise – and uses Kium and S-Alloy rails.<\/p>\n

Castelli Rosso Corsa gravel gear<\/p>\n

As gravel racing has become more serious, it\u2019s become faster. At the business end of a race riders are looking for any gains, however small, just as they\u2019ve been doing on the road for decades. Castelli has recognised the need for speed by giving its gravel range a Rosso Corsa update.<\/p>\n

Rosso Corsa is a tag used for the Italian brand\u2019s most premium items that seek to deliver innovation benefits for elite riders. Here it\u2019s been applied to the two new products: the Unlimited Pro 2 Jersey and the Unlimited Speedsuit.<\/p>\n

Essentially the Pro 2 is the upper portion of the speedsuit sold as a separate jersey. It\u2019s close fitting, with a CFD-optimised shoulder fabric to reduce drag at high speeds. The material used on the body is designed to be breathable yet still offers UPF 30 protection.<\/p>\n

\n

Perhaps the Unlimited Pro 2\u2019s signature feature is the rear pouch, which can hold a 1.5L hydration bladder and hose loops. \u201cFeed zones in gravel racing have become increasingly risky and stressful, but with our Unlimited Speedsuit incorporating hydration pouches and nutrition pockets, riders should be able to fly through them risk-free,\u201d says Castelli Global Brand Manager Steve Smith.<\/p>\n

The jersey is rounded out by three rear pockets, with a zippered option for valuables.<\/p>\n

\n

\"Castelli\n<\/p>\n

The Unlimited Speedsuit pairs the Unlimited Pro 2 Jersey with Free Aero Race S Bib shorts; the latter blends a stretch fabric designed for aerodynamic gains – Castelli quotes a 3% decrease in CdA – alongside a Progetto X2 Air Seamless seat pad.<\/p>\n

\n

Additional storage is a feature here, too. The Shorts have nutrition pockets at the front of the leg, allowing for easy access to food, without having to resort to cargo pockets which add drag due to their side location.<\/p>\n

<\/p>\n

The Unlimited Pro 2 Jersey is available in men\u2019s and women\u2019s and retails at $230.00 \/ \u00a3189.00, while the Unlimited Speedsuit is priced at $420.00 \/ \u00a3360.00.<\/p>\n

Mason Ti seatpost<\/p>\n

Mason\u2019s Aspect and Bokeh Ti framesets are some of the nicest titanium offerings around; like all Mason bikes they blend form and function with great success. The UK-brand is now offering a Ti seatpost, designed to complement the aforementioned framesets – although it will work equally as well with any steel or titanium frame, we\u2019d suggest.<\/p>\n

\n

The Sensor post is offered in both 27.2mm and 31.6mm sizes and are as elegant as they are simple. Using the brand\u2019s find-adjust clamp system it\u2019s compatible with 7mm round or 7x9mm oval rails, while the subtle curve creates a 20mm setback.<\/p>\n

\n

The titanium top cap is forged and CNC machined for lightweight and durability, and the rail support is lightweight hard-anodised aluminium. A hand-brushed finish with a lazer-etched Mason logo completes the look.<\/p>\n

The claimed weight for the 350mm 31.6mm post is 268g. Both sizes retail for \u00a3145.<\/p>\n

Prologo e-bike saddle<\/p>\n

Another new saddle but one for a much different application than the Arione. The Proxim Altius from Prologo is designed for e-bikes, although can of course be used on traditional machines.<\/p>\n

\n

\"Prologo\n<\/p>\n

Given that many e-bikes users ride across varied terrain, from city streets to bumpy tow paths and plenty more besides, the Proxim Altius is focused on providing a comfortable and supportive platform. It has a distinctive V-shape design , with a wide, flat front section and a rise at the rear.<\/p>\n

There\u2019s also Prologo\u2019s Active Base System in effect; essentially it\u2019s a hole in the base of the saddle that is covered by padding to offer a larger support surface as well as keeping you protected from mud and rain.<\/p>\n

\n

\"Prologo\n<\/p>\n

The Proxim Altius is offered in Tirox and Re-Steel rail versions. The claimed weights are 216g and 274g respectively, with the former priced at \u20ac99 and the latter at \u20ac69.<\/p>\n","protected":false},"excerpt":{"rendered":"If there was a Mount Rushmore of racing saddles, the Fizik Arione would surely be present, carved in…\n","protected":false},"author":2,"featured_media":436606,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[37],"tags":[4985,101,56,54,55],"class_list":["post-436605","post","type-post","status-publish","format-standard","has-post-thumbnail","category-cycling","tag-cycling","tag-sports","tag-uk","tag-united-kingdom","tag-unitedkingdom"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/436605","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=436605"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/436605\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/436606"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=436605"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=436605"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=436605"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
