Nukeproof Mega 290 RS Carbon Bike (XO1 Eagle)
The Nukeproof Mega 290 RS features large wheels, superb tyre clearance, exceptional components and modern geometry. Inspired by its competition dominating sibling that blasted the current Enduro Champion Sam Hill to victory two years running, this bike rolls faster and with more stability than ever before and is engineered to dominate on the EWS Enduro circuit anywhere on Earth.
RockShox Ultimate Suspension and SRAM X01 Eagle 12-Speed Drivetrain
This Mega 290 RS Carbon from Nukeproof is equipped with a combination of top-level parts to dominate anywhere on the race-circuit. It features RockShox Lyrik Ultimate RCT3 forks with 180mm of travel up front and 165mm at the rear from a Super Deluxe Ultimate RCT rear shock, this combination gives phenomenal traction and trail gobbling performance anywhere on the mountain side. Powered by only the best, this ride is equipped with a SRAM X01 Eagle 12-Speed drivetrain to blast it efficiently from the summit to the podium while SRAM Code RSC 4-Pot brakes ensure World Class braking power at your fingertips.
Modern 29er Geometry for Stability, Traction and Control
This version of the 29”-wheeled Mega features a frame using a short fork offset with 180mm of fork travel paired with 160mm of rear travel to create a true monster-truck of a bike. To accommodate these changes, Nukeproof slackened the head angle and steepened the seat angle significantly compared to previous versions. They also enhanced the suspension kinematic-performance to make the bike as fast and as controlled as possible. These changes improve its small bump sensitivity, provide greater mid stroke support for more predictable cornering and its increased end stroke progression gives confidence-inspiring control through even the roughest of terrain.
Durable and Lightweight Carbon Fibre Construction
Built and equipped to control the toughest and roughest enduro tracks, this gravity-focussed Mega inspires confidence on the most daring descents whilst ensuring exceptional pedalling efficiency and comfort for epic all-day mountain riding. This top-level race-rig features an award-winning carbon fibre construction at its core. Engineered with a unique blend of the highest quality carbon fibre composites, this lightweight and ultra-durable creation is constructed to win races and lift titles. Enabling you to push harder and faster than ever before, its modern geometry pushes the boundaries of performance and is more responsive, predictable and stable in even the most demanding or conditions.
29″ Mavic Deemax DH Wheels and Michelin Wild Enduro Tyres
Ready for any day in the saddle, this gravity-orientated 29er features DH ready Mavic Deemax wheels and Michelin Wild Enduro tyres rolling beneath it. This wheel/tyre setup tracks with remarkable stability and reliability as it grips and rockets over the roughest terrains with confidence-inspiring control. This bikes cockpit is fully fledged with a Nukeproof Horizon finishing kit, which includes their own award-winning carbon handlebars, Sam Hill Signature grips and a short 50mm reach stem for immensely responsive handling performance. Plus, this bike build has been completed with a Horizon SL saddle and an internally routed RockShox Reverb Stealth dropper seatpost for infinitely adjustable comfort when climbing or descending.

Bike Sizing Guide
Choosing the bike size depends on the type of bike, your height, your riding style, and your preference. A correct fitting bike will be more comfortable, more efficient and more fun to ride. This bike size guide gives our customers general advice on choosing the right size. It is a guide only and we always recommend visiting one of our stores or contacting one of our experts from our contact us page.
To get started, think about your style of riding, measure your height and use the links above for sizing on relevant bike types.
Measure your height
To find the correct sized bike you will need to measure your height and your inside leg. For your height, stand against a wall and mark the wall with a pencil so it's level with the top of your head. Then measure from the ground up to the mark (having someone to help might make this easier). For your inside leg measurement, stand against a wall and using a book hold it in between your legs into your groin and make sure it's flat against the wall. Measure the height from the book to the floor. (Again it might be easier to get a friend to help). If your height is on the cusp of the size range, your reach is often the deciding factor in which size to go for. To find out if you have short or long reach you will need to measure your ape index. This is your arm span minus your height. If you have a positive ape index then go for the larger size, or if you have a negative ape index go for a smaller size.
The type of bike
What type of bike you choose will affect the bike size you buy. The type or style of riding that you do will also affect which size you need. For example a mountain biker that wants to ride more aggressively and would like a more manoeuvrable bike may prefer a size smaller than they would normally take. Likewise a cross country racer that is looking for a flatter and speedier mountain bike may prefer a size larger than they would normally take. There is no definitive right or wrong size, it all comes down to personal preference and what feels comfortable. The different types of bikes are all explained within our buying guides.
How are bikes measured?
Bikes are measured by their seat tube length. This measurement is normally from the centre of the bottom bracket (BB) or the centre of the bolt that attached the crank arms. This differs by brand, some measure to the top of where the top tube meets the seat tube, or even the centre of the top tube. Mountain bikes are either measured in inches or descriptive sizes (small, medium etc). Road bikes are in centimetres or descriptive sizes where as Hybrid bikes can be any one of the three. Bikes also get longer as they go up in size (relative to the frame size) but different brands can be inherently longer or shorter than others.
Stand over height
Stand over height is how tall the frame is from the ground. Stand over height measurements are to the top of the top-tube. Ideally you want at least 2cm of clearance between you and the frame. In theory your stand over height is your leg measurement minus 2cm. It it worth measuring your inside leg with your shoes on so you can establish your stand over height. Should you need to jump off the saddle quickly, the clearance between you and the frame will prevent any injuries.
This handy chart should show you the right size of MTB you need based on your height. Measure your height accurately and check the manufacturer’s measurements too. You can also visit us in store to speak to an experienced member of staff.
