Claud Butler Alpina 1.0 Mountain Bike, 29" X Large (21") Nitro Grey

The Alpina range was rebuilt from the ground up for 2024 — new frame, modern trail geometry, Shimano Cues throughout — and the brief was a bike that could handle UK trail centres rather than just fire roads. The 1.0 is the entry point, with a 2x9 drivetrain that covers everything from canal towpath miles to proper off-road riding.

Who it fits

X Large 21" frame with 29" wheels — the biggest in the range, and as a general guide suited to riders around 6'1" and above. Taller riders are often poorly served at this price point, so this is worth knowing about. Send us your inside leg measurement and we'll confirm before you order.

What you're getting

• Gears: Shimano Cues 2x9 with a 22/36T chainset and 11–36T cassette — a wide spread for climbing and cruising alike
• Brakes: Shimano MT200 hydraulic discs
• Geometry: built around a 100mm fork and 29" wheels, with longer top tubes and slacker head angles. Short 45mm stem and wide 750mm bars for a planted, controlled feel
• Tyres: 29x2.25" WTB Ranger — fast-rolling with good puncture resistance and grip across mixed trail conditions

Stepping up: the Alpina 2.0 swaps to a 1x10 drivetrain with a wide-range 11–48T cassette and a narrow/wide chainset.

Why we can price like this

We're an authorised Claud Butler dealer — but we don't run a shop.

No showroom. No shop floor. No stock sitting in a warehouse depreciating. Your bike is picked and dispatched from the manufacturer's own facility and comes straight to your door.

A traditional bike shop has to cover premises, staff and stockholding before it makes a penny, and that has to come out of the ticket price. We don't carry those costs, so we're not asking you to pay for them.

What you don't lose: full manufacturer warranty, because we're an authorised dealer and not a grey importer. A real person to talk sizing through with before you order. And the option of a professional build so it arrives ready to ride.

Delivery and build

Free UK mainland delivery. Bikes ship boxed and part-assembled as standard. Add our professional build and safety check at checkout and a qualified mechanic assembles, adjusts and safety-checks the bike before it leaves — a real workshop job, and entirely optional. Hydraulic brakes are worth having set up by someone who does it every day.

Klarna and Clearpay available on any order value.
