off.road.cc had a Rocket on Long Term test. Read what they thought about living for a year with our enduro missile:

"...if you are looking for a bike that will help get you out of trouble in the steeps, then this might just be the one."

"Aesthetically I think it’s a great looking bike, it's low slung and purposeful..."

"Great enduro accomplice for fast, long downhill trails with extra get out of jail free cards included."

New Longshot geometry brings a new balance, speed and capability to the 3rd generation Rocket. Long frame, matched with a responsive stem in the 30mm-50mm length range is combined with a slacker head angle to balance out the handling for a beautifully controlled and exciting ride. Better up, better down, better for everyone.

New sizing: Every frame size has been been redeveloped, with attention paid to the riders of that specific frame size.

A new 1x specific swingarm with forged parts brings added stiffness and tyre clearance. Latest generation 27.5 x 2.6" rubber will fit, and Boost spacing and chainline keeps everything futureproof. New 1x integrated One Up top guide (included).

Increase travel up to 157mm at the rear - optimised around 160mm forks, but now certified for up to 170mm travel forks.

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 157mm travel feeling lively and interactive, with grip to spare on the descents, support and traction on the climbs.

    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.

    This frame is hand made in Taiwan by our specially selected framebuilder, chosen because of their vast experience with our favourite materials, and their top quality finish. They are the best in Taiwan for what we need, and have been making our frames to our high standards since day one.

    Each frame is dip coated inside and out with zinc phosphate before painting, to prevent corrosion and ensure the best paint finish. After we've agonised over the colours, designs and decals the frames are painted to the highest quality including a protective clear coat, before extensive QC by our agent in Taiwan. Once the frames reach us in the UK, we carry out further QC, and prep the frames for headset and bottom bracket installation.

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