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.

Geometry and Sizing Chart
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.
