Rocket

  • 27.5" wheeled enduro bike
  • 165mm rear travel
  • up to 170mm fork

The Cotic Rocket is our rough and tough, race proven steel full suspension enduro bike for 27.5" wheels

The Rocket is our wildest and most exciting full suspension bike, and will get you down the rowdiest trails with the biggest grin on your face.

165mm of trail eating travel and the subtly supple Reynolds 853 steel frame gives you ground moulding traction in the corners, and will keep you trucking through the chunkiest rock gardens and most sketchy chutes you can find. Our droplink suspension platform will still let you skip and pop down the trail, seeking out gaps and jumps everywhere, and lets you scramble back to the top like a mountain goat.

Our signature Longshot geometry with its slack head angle, short stem and low standover gets a steeper seat angle and longer reach over the previous model for improved climbing abilities, keeping your weight central over the bike. It balances quick handling from the nimble 27.5 wheels with a swaggering 'bring it on' attitude that needs no encouragement to go blisteringly fast. Developed on tough Peak District trails, the Rocket is ready for anything you can throw at it; from tackling big mountain adventures or the toughest enduro stage, the Rocket will look after you and keep you screaming for more.

"If you like to party on the downhills and cruise on the way back up, the refreshed Rocket is a planted, progressive playmate"

"4.5 Stars Out of 5"

The Gen4 Rocket gets an increase in travel to 165mm, out of a longer stroke shock. This reduces the leverage for a smoother, plusher feel, but keeping the signature interactive Cotic ride.

New Cotic exclusive Reynolds 853 HD tubeset increases stiffness, strength and life of the front end to keep up with those rowdy situations.

The latest iteration of Cotic Longshot geometry brings idealised sizing, longer reach and steeper seat angles to the 4th generation Rocket. Long frame, matched with a responsive stem in the 30mm-45mm length range is combined with a slacker head angle to balance out the handling for a beautifully controlled and exciting ride. Longer reach and steeper seat angles give a better seated climbing position, and longer wheelbase for more stability. Better up, better down, better for everyone.

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. This includes our custom ride tuned Ovalform top tube which helps to deliver sublime trail damping and that signature Cotic feel; lively and fun, yet stable and controlled.

The frames' steel construction is compliant and naturally ground moulding, extracting grip and feedback from the trail where you thought there was none.

27.5" Wheels

The Rocket is designed around the latest 27.5 x 2.6" wide trail tyres, with clearance to spare even with this monster rubber installed. 27.5" wheels are lighter, livelier and easier to accelerates than 29" or 27.5Plus wheels, with a more interactive feel. This is at the expense of slightly less stability and easy rollover on rockier, bumpier terrain. They also more easily package into a small frame - shorter chainstays, lower stack/head tube height - so the proportions suit shorter riders.

Cotic droplink high performance suspension
Cotic Droplink suspension is supportive and progressive, keeping the Rocket's 165mm travel 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 droplink bike 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.

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!

ORDER YOUR FRAME

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.

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.
