The ROADRAT is our take on something fast. But fast isn't enough. It's versatile, simple, tough, and fun.
We use Cotic custom butted cromoly throughout to give a responsive, long lasting frame. Our super skinny stays read across from the SOUL, but in a lighter gauge with tonnes of tyre clearance and superior ride comfort.
V-brake and disc mounts are fitted, because drivers are dopey and we like stopping in a hurry.
Our ROADHOG forks have 45mm offset to keep handling swift, and forward right positioned disc mount for maximum axle security, and you can always fit mudguards regardless of your disc brakes choice. Add in 700c wheels because they're fast, fun and the tool of choice for covering the miles and you've got a serious speed machine that'll take you anywhere.
Cotic Dogsbody dropouts cover all the bases. You want gears and racks for touring? No problem. Singlespeed or fixed for commuting? We've got that too. Disc brakes and knbblies for a bit of 'cross? It's all there, and our clever slotted disc mounts - which actually work with all axle positions - mean you can run trouble free as singlespeed or hub geared with discs.
Custom butted Cotic Cromoly frame and Cotic designed ROADHOG fork.
A mount for everything: Racks, mudguards, discs, v-brakes.
Super versatile Dogsbody dropouts means a bit of what you fancy. Gears, discs, SS, fixed, whatever.
Huge tyre clearance. Why not? Big road or cyclo-cross tyres (up to 42c), or even 26" wheels with massive 1.8" slicks if you're using discs and want to go super comfy. How about 650B ? Popular with many tourers, and gaining popularity in the mountain bike world, these can be used with discs on the ROADRAT as well.
In between dropout spacing at 132.5mm. Run road or MTB spacings with no problems thanks to the joy of springy steel!
Flat bar model features optimised handling and rider fit. No toe overlap, no twitchy handling, no back ache, no worries!
Drop bar model features classic top tube/cockpit dimensions combined
with super compact frame layout, and confident front end geometry.
Geometry and Sizing Chart for flat bar model
The chart is a guide to frame size for the original 'long' version of the ROADRAT: Ultra Compact Geometry - Road means that the frames are low and long. You'll probably need a 350mm seatpost due to the compact sizing, and as a guide, the top tube lengths are identical to the Soul/Soda if you're coming over from mountain bikes. You lot are just too different to say for sure, so 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.

Geometry and Sizing Chart for drop bar model
We had lots of enquiries for people wanting all the utility and
setup options the ROADRAT gives you, but in a more classic road bike layout.
There are now new 'short' sizes of the ROADRAT for those people. These are identical in
every way to the existing ROADRAT design, but shorter in the top tube to
allow 90-120mm stems to be used which achieves more sensible drop bar
handling. Confused? Drop us a line
at size@cotic.co.uk to find out which size you need.
