Cotic Solaris Trail Silver

£3,647.00

Solaris is the hardtail for riders who want speed and simplicity without giving up composure when the trail turns serious.

There's a particular feeling you get on a well-built steel hardtail, a rhythm between you and the trail that full-suspension can smooth away. Solaris is built around that feeling. Light under power. Direct when you push on the pedals. Calm and planted when things get rough.

Why Solaris Makes Sense

You’ve been riding bigger bikes and crave something sharper.
You miss the clarity, rhythm, and connection of a hardtail.
You're a gravel rider who wants more trail options, more capability, more places to go and ride.
You want one bike that handles long days, winter mud, local woods, and climbs without compromise.

Solaris delivers that balance, and then some. Reynolds 853 steel and Cotic Longshot handling means this isn't a compromise bike or a nostalgia trip. It's a serious machine that happens to remind you why you started riding.

Built on Experience

Cotic has been building this type of bike since the Soul in 2003. Twenty-two years of iteration, rider feedback, and quiet obsession with getting steel hardtails right has led here. It’s built from Reynolds 853, a proprietary heat-treated steel that is stronger than standard steel tube. This makes the frame lighter and more compliant without losing the toughness steel is known for. It’s hand made and finished in the EU. Solaris is simply the best hardtail we have ever built.

Colour Availability - We have the last few Limestone coloured frames in stock now. Cirrus Grey is the 2027 colour and you can order now for delivery January.

The Silver Trail build brings a Rockshox Pike Select 130mm fork to the party for extra speed and control in rough ground. Kitted out with your choice of Shimano XT Mechanical or SRAM Eagle 90 drivetrain you have benchmark, reliable mechanical gears whichever your preference is. Tougher Hope Fortus wheels and grippier Romy tyres are on board for those who ride rougher, steeper ground more of the time.

Where is the Cotic Solaris made?

The Solaris frame is handbuilt in Czechia, with complete bikes assembled to order in the UK.

Will I pay Import Duty?

What's the difference between the Solaris and the Cascade?

What's the difference between the Trail and Downcountry Solaris builds?

Both share the same frame and geometry. Trail builds are specced for all-round trail riding, while Downcountry builds use a different wheel and tyre setup geared toward faster, lighter riding without sacrificing capability.

Is there a difference between the 2024 and 2025 Solaris frames?

Yes. 2024 Matte frames use a Cotic 12x148 rear axle (M12x1.75 thread) and a Cotic-specific rear mech hanger. 2025 Gloss frames use a Burgtec 12x148 rear axle (M12x1.0 thread) and a UDH hanger, compatible with SRAM Transmission.

Can I get the Solaris in a custom colour?

Yes. The Solaris Frameset is available as an A La Carte option with your choice of colour, finish and decal colour. On complete bikes, A La Carte paint is available as a £250 upgrade, less than on Cotic's gravel bikes since the Solaris fork doesn't need painting.
