Steel beats carbon: Three brilliant hardtail frame sets for under 1,000 euros!

Conclusion by Max Fuchs, BIKE editor

Sometimes all you need is a good steel frame, a rigid fork and wide tyres. The Brother Cycles Big Bro, the Surly Bridge Club and the Nordest Sardinha 3 deliberately do without technical bells and whistles, focusing instead on versatility, durability and riding enjoyment. All three frame sets cost less than 1,000 euros and form the perfect basis for a bespoke bike – whether you’re a bikepacker, a commuter or a touring cyclist. The main differences lie in their character: the Brother feels right at home on long journeys, the Surly tackles any terrain with stoic composure, and the Nordest brings a modern, sporty touch to the classic steel design. Another welcome feature: all three models feature post-mount brake mounts. This means that virtually all standard MTB brakes fit the bike without the need for an adapter. This is by no means a given in the adventure sector – where flat-mount mounts, more commonly associated with road and gravel bikes, still dominate in many quarters.

Less technology, more cycling

Whilst mountain bikes are becoming increasingly complex, enthusiasm for the opposite is growing at the same time. Rigid forks instead of sophisticated suspension technology, steel instead of carbon, and a relaxed riding position instead of a stretched-out racing posture – it is precisely this combination that makes modern adventure hardtails so appealing. Their roots go back to the legendary ‘Klunker’ mountain bikes from California, the forefathers of the mountain bike. Today, they combine this simple concept with modern gear systems, generous tyre clearance, disc brakes and countless mounting options for bags, water bottles and luggage.

It’s in bikepacking, in particular, that these bikes really come into their own. Fewer moving parts mean less maintenance, greater reliability and easier repairs on the go. At the same time, this makes for excellent everyday bikes that handle the commute to work just as effortlessly as a weekend trip to the lake – and look absolutely stylish to boot.

Anyone looking for a steel hardtail of this kind in Germany will, however, quickly realise just how limited the range actually is. Whilst aluminium and carbon bikes dominate shop windows, many of the most exciting steel frames come from small manufacturers in the UK or the US. Direct imports often come with high delivery costs, import duties and – depending on the country of origin – additional customs charges. This makes models that can now be sourced relatively easily through European retailers or specialist importers all the more appealing.

Brother Cycles Big Bro – The Globetrotter

Brother Cycles was founded in London in 2010 by brothers Will and James Meyer. Rather than bringing as many models as possible to market, this small British brand continues to focus on a select few bicycles, each thoughtfully designed down to the last detail. Brother enjoys an excellent reputation, particularly within the international bikepacking scene. The bikes have a timeless, robust look and deliberately steer clear of short-lived trends.

The Big Bro perfectly embodies this philosophy. The frame was designed for long journeys and great adventures, but is just as at home in everyday use. Numerous eyelets on the frame and fork accommodate bottle cages, Anything Cages or lowrider pannier racks. The balanced geometry is designed to provide a high level of confidence even when heavily laden, without feeling sluggish. Thanks to generous tyre clearance, the Big Bro rides with confidence even where gravel bikes get stuck. If you’re looking to build a bike for just about anything and can do without high-tech features, the Big Bro offers an extremely versatile platform.

Surly Bridge Club – The American all-rounder

Hardly any other manufacturer has shaped the modern steel frame quite like Surly. Since the late 1990s, the US company from Minnesota has been developing bikes that defy categorisation. Rather than specialisation, their motto is versatility. That is precisely why Surly is now regarded as a cult brand amongst touring cyclists, bikepackers and everyday riders alike.

The Bridge Club epitomises this philosophy. It combines classic mountain bike DNA with a relaxed touring geometry and enormous versatility. Whether you opt for fast 29-inch wheels or comfortable 27.5+ tyres – hardly any other frame allows for such a wide range of set-ups. The riding position remains comfortably upright, numerous threaded eyelets make it easy to carry luggage, and the robust construction can easily handle even heavy loads. The Bridge Club is therefore one of the most versatile steel frames around.

Nordest Sardinha 3 – The sporty steel hardtail

Nordest hails from Portugal and is one of Europe’s most exciting young brands. Rather than relying on mass production, the company consistently focuses on steel and titanium frames with modern geometry. The result is a range of bikes that combine classic materials with the latest trail expertise.

The Sardinha 3 is therefore said to ride much more dynamically than many classic steel hardtails. According to the manufacturer, the long reach, slack head angle and short rear triangle ensure plenty of control off-road whilst also giving the bike a surprisingly playful character. At the same time, the riding position remains comfortably relaxed – perfect for long days in the saddle. Ample tyre clearance and numerous mounting points make the Sardinha 3 just as much a sporty bikepacking bike as it is an exceptional everyday bike.

Editor’s note

The Brother Cycles Big Bro, the Surly Bridge Club and the Nordest Sardinha 3 impressively demonstrate that modern mountain bikes do not necessarily require suspension travel, carbon or high-tech features. Instead, they rely on a material that has been delighting cyclists for decades and is now more relevant than ever. Steel offers comfort, durability and a distinctive character – qualities that really come into their own on long tours and in everyday use.

It is also worth noting just how small this market segment has actually become in Germany. Whilst manufacturers here rely almost exclusively on mass-market aluminium and carbon platforms, many of the most interesting steel frames are produced by small brands in the UK or North America. However, importing them is often a complicated and expensive process. High delivery costs, import duties and, in some cases, additional customs duties can quickly make supposed bargains considerably more expensive.

That’s precisely why the Brother Cycles Big Bro, the Surly Bridge Club and the Nordest Sardinha 3 are currently among the most exciting options for anyone looking to get into the world of modern steel hardtails without the hassle of importing. Three different characters, one shared philosophy: less tech, more bike.
