Availabilty
The Cotic Rocket is our 150mm travel full suspension frame.
The Rocket is a swaggering speed machine. It brings together the grace, durability, clean lines, fun, interactive feel and attention to detail we put into all our hardtail frames and adds a whole truckload of speed and rock pounding performance. It's an Enduro race weapon which the Cotic Steel City Media Racing team took to multiple podiums in 2013.
The Rocket uses Reynolds 853 front triangle, cromoly seatstays, and 7005-T6 swingarm. They are amazing materials which deliver the durability, strength and confidence a bike like this needs.
The details are all covered, with ISCG05 mounts, taper steerer compatible head tube, 142 x 12 bolt thru back end, sealed, capped and shielded pivots, right down the precisely located hose routing.
The original Rocket with 26" wheels described here was produced in 2012 and 2013. It is no longer available. All the geometry and specifications for this frame as listed below.
The frame was supplied in 2012 and 2013 with one of the following shock options:
- Fox Float RL
- 2012 Model Year Fox RP23 Factory Kashima
- 2013 Model Year Fox CTD Factory Kashima
- BOS Vip'r
If you need a copy of the Owners Manual, with details on the pivot maintenance, bearing specs, and shock setup, you can download it:
Cotic Rocket 2012-2013 Owners Manual Download
In Summer 2015 the Rocket got 27.5" wheels. Read about that here.
- Reynolds 853 Ovalform and DZB tubed front end brings precision, durability and strength
- 44mm standard head tube designed with external bottom cup for taper steerer compatibility and zero stack top cup for minimal stack height
- Oversized 35mm seat tube for super stiff support for the main suspension pivots
- 31.6mm seatpost size is dropper seatpost compatible and the frame has top tube bosses for external routing, or a seat tube slot for stealth.
- ISCG05 mounts on regular threaded bottom bracket bring drivetrain security and reliability
- Torque Box Swingarm with Reynolds 631 stays and Syntace X-12 142 x 12 rear axle
- 15mm pivots for BB and droplink keep the frame solid front to rear
- Clearance for big tyres - 2.5" DH tyres run with plenty of clearance
- Geometry for speed, fun and interaction using 140, 150 or 160mm forks. 66.5deg head angle and low 13.3" BB with 150mm fork
- 150mm of Cotic droplink suspension brings precision, fun and interaction via a strong progression rate on the linkage driven single pivot layout
- Sizes - 16", 17.5", 19". The frames are designed to be compact and chuckable.
- Weight - 7.6lbs for the 16" including Fox Float CTD EVO shock
The chart is a guide to frame size. Ultra Compact Geometry means that the frames are small and long. You can take this two ways. You can either have a regular position coupled with a small and chuckable frame, or you could go for the next size up and go long and racey without feeling like you're riding a gate. We don't make an XL Rocket26 for really tall guys, sorry. If you want to discuss fit and setup further 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.

17/01/2012 : Why steel? - Final Rocket Essay
Cy wrote his final piece on the new Rocket in our newsletter last week. Here it is in our Geek page. There's a fair bit to it, so make yourself a cup of coffee and grab a few mins to sit down and have a read.
Cy's Why Steel? Essay...
09/01/2012 : Rocket Pricing
We have confirmed pricing on the Rocket. We are running with four shock options which should cover the bases for most people. As usual, price includes a Hope seat clamp, chainstay protector, bottle boss bolts, hose clips and delivery.
£1,350 - Fox Float RL
£1,400 - Marzocchi Roco Air LO
£1,475 - Fox RP23 Kashima
£1,580 - BOS Vip'r Custom Tune
At the moment we don't have a coil option, but if demand is there we can get pricing on BOS Stoy, Marzocchi Roco and Fox DHX should you so wish. Drop me a line if you want to talk it over.
We'll be offering the Hope headset (2H) which is compatible with the 44mm head tube on the frame. Price when buying from us here at Cotic is £65 fitted, plus £10 for the 1.5 to 1 1/8" crown race adaptor if you need to run a straight steerer fork.
19/12/2011 : Introducing droplink
The latest newsletter was sent on Friday (sign up here) with a lot of information about droplink, our new suspension platform. For those you not signed up to the mailing list, we've put the information on our Geek section for your reading pleasure. We're warning you, it contains the words anti-squat and rate curve more than once!

09/12/2011 : Cotic Rocket - 2nd Installment
For the second installment of the information on the Cotic Rocket, Cy's done a video explaining about the origins of the project, and what he sees as the key points on the bike. We hope you like it.
Here's the overall specification for the bike:
- 150mm rear travel, using Cotic Droplink suspension (more detail on this in the next newsletter).
- Slack, low geometry: 66.5 degree head angle/13.3" BB height with 150mm Fox Float installed.
- Designed for use with 140, 150 and 160mm forks.
- Front triangle constructed from Reynolds 853, swingarm 7005-T6 aluminium, seatstay/shock strut in cromoly, droplink is 1 piece CNC'd 7075-T6.
- 7.6lb frame weight including Fox RP23 shock.
- 44mm standard head tube, designed around zero stack top/external cup bottom for taper steerer compatibility.
- 31.6mm seatpost size for dropper seatpost compatibility, and hose clips for remotes under the top tube.
- ISCG05 mounts.
- Syntace X-12 142 x 12mm rear through axle.
- Loads of tyre clearance. Easily runs with Maxxis 2.5" DH tyres in the rear end.
- Regular 73mm threaded BB shell.
- 15mm pivot axles on both main pivot and Droplink pivots combine with massively stiff 35mm steel seat tube to lock the back end to the front triangle for maximum handling precision.
- Shock options will include Fox Float RL, Fox RP23 Kashima, and custom tuned BOS Vip'r.
25/11/2011 : The New Cotic Full Suspension Frame
For the last 2 and a half years we have been working on a new full suspension frame. It's finally finished and going into production, so we wanted to announce that we're back in the game and they're due in mid-March 2012.
The frame is called the Cotic Rocket. It's a trail bike with 150mm rear travel for 140-160mm forks. We have so much to tell you about, but Cy's going to do that in detail over the next few weeks in (relatively) easily digested chunks via the mailing list.
It has been a long project, and we're incredibly proud of this bike.
Stay tuned!
For frames bought before 1st September 2019 have a warranty which entitles the original owner to a free replacement within 2 years of purchase and half price replacement within 3-4 years of purchase inclusive should there be any problem with the materials or workmanship on the frame. This does not cover abuse, and use of the bicycles outside stated parameters (see your user manual). Should any modifications be made to the frame during the warranty period, which includes removal of the original paint coat for refurbishment, the warranty is void. Shipping of a returned frame will be compensated up to a maximum of £10 should the frame be accepted as a warranty claim. This does not cover any components supplied additional to the frame. Your statutory rights are not affected.
Remember: Minimum seatpost insertion is 100mm into the frame regardless of what it says is the minimum insertion on your seatpost.
Note: Fork compatibility is defined by travel not length. We understand that some manufacturers forks are shorter in height than others, but this is irrelevant. If you run forks with longer travel than we have stated for a given frame, warranty is void and likelihood of damage or failure of the frame is high.
