Tech Overview
The Purpose
When we launched the 161, many riders loved the Enduro World Series race-focused concept, but we know not everyone has access to world-class steep and technical alpine trails. We listened, and here it is, the 141.
Built to handle everything from your local trail loop to park laps, or even a local Enduro race or two. Taking our proven platform and stretching out the seated position slightly gives riders more room to enjoy those undulating sections of trail.
The 141 is ready to ease you to the top with its steep climbing position, whilst its progressive geo will let you focus on the next chute, tight switch back or fun side hit on the way back down.
Who said versatility has to be boring?
Key Features

Build Rationale
As a rider you’ll spend a lot of your time in the saddle, inching ever closer to the summit and the start of the next trail, so you want somewhere supportive yet comfortable to sit. Touch points like saddles and grips are incredibly personal so finding the elusive ‘one size fits all’ is nigh on impossible, yet Fabric comes close.
The Scoop’s three-piece construction bonds a waterproof microfibre straight onto a flexible base, allowing for the use of a softer foam – not only comfortable, but super easy to clean and extremely durable. Funguy grips combine the vibration damping of a mushroom grip with the control of a micro-hex pattern and the grip of a soft compound rubber, leaving you to focus on the trail ahead.
OneUp get the need for long travel/short insertion and are obsessed with shaving every last millimetre to create the shortest stack height and shortest overall length of any dropper. The ability to shim down the travel by 10 or 20mm means we can confidently fit longer posts knowing riders can get their saddle where they need it.
Combine this with an innovative ergonomic remote and unsurpassed reliability (if something does go wrong its easily serviced at home) means the One Up V2 Dropper is truly in a class of its own.
An office favourite, Schwable have been producing class leading and race winning tyres for decades. As the only point connecting you to the trail beneath, we know the choice of tyre not only determines how much grip and speed you have, but also your confidence to tackle the next feature.
Magic Mary, an indisputable favourite among Schwalbe’s Enduro athletes, is a perfect all rounder for almost all tracks and conditions, while a Hans Dampf out back keeps grip high and rolling resistance low.
Fox have been around since 1978 and in those 42 years they’ve taken a number of world firsts and been at the pinnacle of racing suspension ever since. Few, if any, brands have taken wins in Superbike, Motocross, Indy car, Snowmobile, ATV and of course Mountain Bikes.
For 2021, Fox updated the 36 fork to include their new Grip 2 Damper and a revised chassis, making it “smoother, stiffer and more tuneable than ever”. Whilst the DPX2 received an entirely new base valve design and the addition of a valved circuit in open mode, raising the already high bar for trail category performance.
When you’re flying down a steep section, the last thing on your mind should be if your brakes are going to stop you - Magura’s MT5 offer heaps of controllable power. Enduro Mag goes as far to say “braking torque and deceleration were brutal – but rich in German precision. Wet or dry, the Maguras hauled down speed quickly, and were nothing but reliable.”
Combining 17mm twin pistons, with 2mm thick Storm HC rotors (203mm/180mm), provides huge amounts of power but also stability and improved heat dissipation ready for any alpine descent.
Having produced freewheels for nearly 100 years, Shimano’s drivetrain reliability is indisputable. Known for taking their time to perfect a product, in SLX they created a versatile, durable yet smooth-shifting system.
Using SLX where it was practical, as no-one likes replacing expensive mechs when you crash, we prioritised the shifting experience by upgrading to an XT shifter. Compared to its sibling, XT offers a proven multi-shift function, allowing you to shift down two gears at once when the trail takes an unexpected turn and to avoid missing any key shifts, it also features rubberised thumb pads.

Coil too?
The frame is designed to run great either a coil or air shock.
Does it fit a water bottle?
Yes! We'd recommend up to a 500ml bottle in a side load cage
Can I set the bike up mullet? (29" Front and 27.5" Rear?)
No, we do not recommend this set up as it will make the bottom bracket too low and slacken both the head and seat angles.
Can I run Plus Size?
The 141 was not intended to run plus, but can clear a 27.5x2.8 tyre. This will lower the bottom bracket height slightly.
