Cotic : RocketMAX : 29er Enduro Full Suspension Mountain Bike : Reynolds 853 Steel : 160mm Travel : droplink : Made In Britain

The Cotic RocketMAX is our big wheel, blazingly quick, 29er steel full suspension enduro bike


The fastest bike in our fleet. The radical, UK made RocketMAX turns the speed up to 11. It's all about the rockiest descents and the steepest technical trails. It's confident and blisteringly quick.

RocketMAX will carry speed through lines you've battled to get through before, and will do so with composure and ease thanks to it's Reynolds 853 steel frame, leaving a big grin on your face. You like steep and techincal? You can ride down pretty much anything on a RocketMAX, then pedal back up buzzing on how great your ride is. Incredible stability and pinpoint precision brings you swaggering confidence regardless of the gradient.

RocketMAX is wild and fast and just so much fun. It's almost like cheating!

Rear BikePerfect's 4.5/5 review of the RocketMAX Gold Eagle bike:

"....an enduro tank that stays utterly calm and confident well beyond our test team's normal panic points and takes up position as one of the fastest gravity bikes we've ridden - regardless of material or origin"

"If you want a bike that delivers all the damping and shock shrugging advantages of steel, while retaining a warm sense of spring but never twanging too far off line then it's fantastic"

Cotic frames are designed, developed, engineered and tested entirely by us at our base in the Peak District, near Sheffield in the UK. Our founder - Cy Turner - is the lead designer and engineer, and our frames are rigorously ride tested by everyone at Cotic, and our Race Team. They are fully certified and lab tested in excess of the requirements of ISO4210 safety standards.

For this frame the majority of the production process happens right here in the UK! The skilled guys at Five Land Bikes in Scotland manufacture the Reynolds 853 front triangle in small batches, to their exacting standards. This is married to our proven rear ends and linkages from our excellent suppliers in Taiwan, as found across our droplink range. Much of the remaining machined parts are made by Superstar Components in Lincolnshire.

All the major parts of the frame are dip coated in manganese phosphate to prevent corrosion, before being painted using tough and durable automotive spec paint by the Five Land guys. The graphics on these frames are masked and painted, rather than stick on decals, for a seamless top quality look beyond anything you would normally expect on a production bike. After Five Land Bikes have completed this painstaking hand finishing process and their rigorous QC, the frame parts undergo further checking by us before assembly at our HQ in the Peak District.

As a final added extra, all UK made frames are Datatag'd from the factory. You will receive all your Datatag documents with your frame or bike when it's delivered.

As always, all complete bikes are built to order by us here at Cotic, to the exact spec of your choice. We build your bike for you.

Cotic Longshot Geometry, Longshot geometry, progressive geometry, mountain biking, enduro mountain biking, trail riding, mountain bike, full suspension mountain bike, 29er, 29 inch wheels, 27.5 inch wheels

Radical Longshot geometry keeps the bike stable through the rough stuff, planted in the corners and pinpoint accurate in the steep tech. Couple a super short 35mm stem to the optimised head angle and the bike really pushes you on, looking for every stump to boost off, rock to gap and berm to rail, keeping you connected to the trail while maintaining incredible poise and composure.

Reynolds 853

Reynolds 853 builds a light, lively and fantastically robust front end, and includes our custom ride tuned Ovalform top tube which helps to deliver that famous ride feel. The frames' steel construction is compliant and naturally ground moulding, extracting grip and feedback from the trail where you thought there was none.

MAX

Cotic MAX frames use 29 inch wheels. MAXimum speed, MAXimum rollover.

29inch wheels roll easy and give a lot of stability, confidence and speed in rougher terrain, at the expense of being a little heavier and less playful than regular 27.5" wheels.

Why Big Wheels?

The way the MAX frames are packaged around the larger wheels (longer rear end, longer wheelbase, taller front end) can suit the proportions of a taller rider better, this will minimise any potential drawbacks, as a taller rider tends to have long enough arms and legs to move the bike around easily. Whatever height you are, if you're after more speed and stability from a bike, then the big wheels are the way to go.

MAX
Cotic Droplink suspension is supportive and progressive, keeping the 150mm travel RocketMAX feeling lively and interactive, with grip to spare on the descents, support and traction on the climbs.

We Build Your Bike For You

All Cotic bikes are assembled in the UK from and frame up. We have set specifications, but these are just the start. Want the Silver spec bike with tubeless tyres? Easy! Want a big can air shock on your RocketMAX instead of the inline? It's there too. Full colour matched Hope parts, and add the matching brakes too? It's a click away, and everything else in between. If it's not a choice on the order form, just ask.

When you contact us you are talking to the people who design the frames and will be building your bike. We check it and build and pack it in our award winning bike boxes with the same care we would our own bike, because we know how important it is. We build your bike, for you.

Is the RocketMAX the bike for you?

If you like the idea of an enduro bike from Cotic, but with the lighter, livelier ride of the smaller 27.5" wheels, you need our Rocket.

Like your wheels big, but more of an all rounder? A little more responsive and shorter travel? You need the FlareMAX.

Maybe you're more a hardtail rider, but like the speed and security of the RocketMAX with 29er or 275 Plus wheels? Have a look at the SolarisMAX.

ORDER YOUR FRAME

Complete bikes from: £2899

Bikes are now available worldwide, with free shipping to UK, Ireland, Europe, USA and Canada.

We have several levels of stock build which are based around our favourite parts in builds you can trust. We never specify anything we haven't ridden, tested and enjoyed. However, just about everything in your build can be customised to help with fit (contact us if you need help) or to personalise your bike. Want a different fork? Shock? Brakes? Wheels? Tyres? Bars? Stem? Longer drop seatpost? Women's saddle? Colour matched Hope components? No problem. It's your bike.

All the bikes are assembled from a frame right here in the UK by us. We can do everything from bare frame to complete bike: Send us your favourite saddle and grips to fit. Send us your wheels if you have a nice pair you want to use. There's no point you getting kit you don't want. It's wasteful. That gives you almost limitless options to customise and tune your bike to your needs. If you can't see an option you'd like on the order form, get in touch. We all know it's good to head off piste sometimes!

CONFIGURE YOUR BIKE

The chart is a guide to frame size. Longshot Geometry means that the frames are low and long, with plenty of standover room. We recommend going for the size suggested for your height on the chart, and getting all the benefits of running a super short and responsive 30-35mm stem. It's a game changer. Make sure you consider your leg length as well. If you upsize you might not be able to fit a longer dropper post due to the collar hitting the seat tube top or the dropper post bottoming out on the seat tube droplink pivot. If you are unsure about that or anything else, drop us a line at size@cotic.co.uk and we'll be happy to discuss set up based on what you're riding at the moment and what seatpost you are planning to use.
