Description

Using the Fatty Trail X01 as our inspiration we've built up another Fatty Trail that delivers all the smiles per miles for the more price conscious rider. We all know that there's only one way to improve on a fat bike and that's to bolt on the best performing wide hipped suspension fork on the market. The Fatty trail X5 has been designed from the ground up to accommodate 4" tyres that deliver amazing traction, floatation and stability- add the Rockshox Bluto 120mm travel suspension fork into the mix and you have an unbeatable combination.

We've thought long and hard about the specification for every part of the Fatty Trail X5. We've chosen a SRAM X5 2x groupset that matches up a 2x chainset with a wide ratio 10-speed cassette to deliver a huge gear range. No matter what confronts you on the trail you'll never run out of gears to attack the climbs.

You've no right to expect a hand built wheelset on any bike at this price but we've delivered a wheelset with an incredible combination of performance and durability. Using on new 6-pawl, El Guapo fat bike hubs they offer instant engagement and are triple sealed to keep even the worst of the British weather on the outside season after season.

The control centre of the Fatty Trail is bristling with home grown products. Our El Guapo Ancho alloy handlebar is paired up with an On-One Hot Box stem to give you tight and precise steering. Squeezed in between a pair of On-One Half Bob Lock-on grips you'll find a pair Avid's DB3 hydraulic brakes. We really have maxed-out on the parts quality for this X5 Fatty Trail build- there's nothing to touch it at the price.

The Fatty Trail is capable of swallowing up any trail that you put in front of it and it's guaranteed to keep on trucking through the rough stuff. It's the logical upgrade from our original Fatty Fat Bike and is guaranteed to put a huge smile on any rider's face. We knew from the very first test ride that we'd created something special, something big.

What is the Fatty Trail X5 for? The answer is simple, what isn't it for?
