2026 新款礫石車：八款亮眼車型大比拚

導論

對礫石車來說，五月是個熱鬧非凡的月份。各品牌同時朝不同方向推進，有些車款看起來幾乎像公路車，有些則刻意騰出空間容納登山車胎，還有幾款一味追求極低重量。結果是選擇比以往更寬廣，但也更難理出頭緒。

以下八款車說明了 2026 年礫石車設計的走向。有些是為純粹的競賽速度而生，有些則偏向耐力、收納與避震相容性。該選哪一款，取決於你實際騎乘的地形，以及你如何定義一輛快速的礫石車。

評估標準

比較這些車款時，主要的差異點在於輪胎間隙、車架重量、空力數據、安裝孔位，以及車輛在崎嶇地形上的操控表現。如果你當地的礫石路面鬆散或布滿石塊，輪胎間隙最為關鍵。車架重量與空力數據對競賽更重要。收納空間與避震相容性則是超長距離耐力賽與單車露營的關鍵。價格與供貨情況同樣差異極大。

Specialized Crux：輕量空力速度

第五代 Specialized Crux 看起來就像一輛能容納 55 mm 輪胎的 SL8 Tarmac。它採用邊緣極度鈍化的輪組，設計目的是減輕騎士在顛簸地形上的疲勞。與 Tarmac 一樣，它非常輕。

S-Works 車款宣稱車架重量為 789 公克，成車重量從 6.9 公斤起跳。Specialized 宣稱它在 Unbound 200 中快了將近 10 分鐘，部分原因是它在時速 45 公里時，比前一代快了 15.2 瓦。每一根管型都經歷了大幅改動，成果是一輛外型好看、具備充裕間隙、重量輕且幾乎沒什麼妥協的車。據說操控也調校得相當到位。主要缺點是價格。

Look G85 Cesal：有極限的全能型

Look G85 Cesal 是一款主打性能的礫石車，定位上更接近全能型。它並未提出任何空力數據。在 Sea Otter Bike Show 上，曾有人目擊一款外型更偏競賽、且未整合收納空間的版本。

G85 Cesal 可容納 50 mm 輪胎，這可能讓它比間隙更寬的對手更快顯得過時。外觀設計也評價兩極。車架組要價 2,500 英鎊，車架重量 1,090 g，卻又沒有空力數據加持，對某些騎士來說可能會覺得不值。

Factor Ostro Gravel：寬叉空力原型

一款尚未發表的 Factor 礫石車在 Tracker 活動中現身，看起來大量借鏡 One Aero 公路車的技術。超寬前叉設計的概念是：空氣本來就會被騎士的雙腿擾亂，因此前叉在紊流中產生的阻力會比在層流中更低。

這款原型車至少能裝 53 mm 輪胎，前端看起來還能容納更寬的規格。它也有與 Factor Monza 設計類似的下管收納空間。Ostro Gravel 已顯老態，而這看起來是一次激進但受歡迎的更新，具備 2026 年礫石競賽車該有的特點。它不會適合所有人，因為 Factor 持續打造的是專家級工具，而非追逐廣泛客群。

Factor Saronna：長途萬用性

The Factor Saronna is designed to go long and go fast. It is covered in mounting points, can be bought with a suspension fork, takes 57 mm tires, has down tube storage, and uses a rear end designed to act like a leaf spring for comfort. It is built for ultra-endurance races, but it may be the most versatile bike Factor has ever released.

Custom bags are available, and the frame is suspension corrected for a 30 mm travel fork. One particularly useful detail is the standard round 30.9 mm seat post, which opens up more dropper post choices. The negatives are limited colors and a website claim about zero structural drift in stiffness after 40 hours of continuous simulation that could use more context.

Felt Breed：輕量但前叉有疑慮

Felt is back with a new road bike and a new gravel bike, the Breed. It is light, though not as light as the Crux, with a sub-1 kg frame and complete builds close to 7 kg. It carries plenty of aero claims and can take a 54 mm tire at the front and a 52 mm tire at the rear.

The Breed uses the same bar as the new road bike, but the height of the fork is hard to overlook. Felt says it is suspension adjusted, but on a lightweight race bike that choice seems confusing. If you want to fit suspension to your gravel bike, a frame that accepts more than a 52 mm rear tire may make more sense.

Argon 18 Antimaher：收納與風格

The Argon 18 Antimaher launched in the middle of May. It is a good-looking bike with integrated storage and custom bags made in partnership with Apidura. It ships with Zipp Super-Wide Explore wheels and fits up to 55 mm tires.

The seafoam and neon colorway stands out, and the bike looks like a nice piece of kit in person. Argon 18 had a tough few years around COVID, so it is good to see the brand back firing on all cylinders. This is a bike that is very appealing for riders who want storage and wide clearance without going full endurance.

BMC Kaius：純粹競賽速度

The new BMC Kaius is described by the Swiss brand as a pure gravel racing bike that is faster and more capable than ever. It has BMC’s own carbon wheels with carbon spokes, space for up to 52 mm tires, aero bottle cages, and a clever bar system that looks less fiddly than some integrated cockpits. It weighs 7.1 kilos and looks good.

There are a few things to change. It ships with Continental 45 mm Terra Speed tires, which are very fast but niche, and they would not be much good on some gravel. The Kaius is worth considering if you want speed and do not need mountain bike tire clearances.

Canyon Grail CFR：尚未發表但值得期待

The final bike is a new Canyon that has not yet been released, so there are no official figures. It looks a lot like a new Grail CFR. Canyon has not been afraid to try new things on the Grail in the past, including a double decker handlebar that put some riders off, but this one seems to follow the new norm.

It has super wide clearances, aero touches, and an aero handlebar. Until Canyon releases official details, it remains one to watch rather than a confirmed option.

整體選購建議

The right gravel bike here depends on your priorities. If you race on fast gravel, the Specialized Crux, Factor Ostro Gravel, BMC Kaius, and Felt Breed are the most speed-focused options. If you ride ultra-endurance events or want to carry bags, the Factor Saronna and Argon 18 Antimaher make more sense. The Look G85 Cesal is an all-rounder with storage, but its 50 mm tire clearance is a limitation to weigh carefully.

Tire clearance is the first thing to check. Bikes with 50 to 52 mm clearance suit fast, smooth gravel, while 55 to 57 mm coverage opens up rougher terrain and mountain bike tires. Suspension compatibility matters if you want a more comfortable front end on long descents. Storage and mounting points matter if you plan to bikepack or race ultra-distance events.

Frame weight and aero claims are most relevant for racing. The Specialized Crux and Felt Breed are the lightest options here, while the Factor Ostro Gravel and BMC Kaius lean into aero design. The Canyon Grail CFR could be a strong contender once official specifications are available, but for now it is an unreleased model with no confirmed figures.

結論

These eight gravel bikes show how varied the category has become. Some chase road-bike speed with wide tires, some prioritize tire clearance and suspension, and others focus on storage and long-distance comfort. Match the bike to the terrain you actually ride, and the choice becomes much clearer.
