The all new Cotic Roadrat is here.

The frameset was born from a desire for something swift and rugged to take on everything from the rapidly crumbling tarmac of the urban jungle to disappearing into the hills for a few days with nothing but your sleeping bag and mat for company. Faster than a mountain bike on the road, way more fun and versatile than a road bike, it's your perfect 'other' bike.

New for 2013 the Roadrat has updated geometry with lower BB and longer head tubes for better fit and more stable handling, simplified and improved dropouts with integrated mech hanger and chainstay mounted disc mounts, revised tubeset with Cotic signature Ovalform top tube and new taper leg RB2 forks, all wrapped up in two gorgeous new colour options.

The Roadrat is our take on something fast, when being fast isn't enough. It's fun, versatile, simple and tough as old boots.

The new Roadrat gets an updated cromoly tubeset using the latest Cotic Ovalform top tube, lighter stays and revised geometry for better handling and more comfortable fit on the bike.

The RB2 fork is carried over from our latest >X< frame, with taper legs for subtle ride feel, and now with a clean disc only option and colour matched to your frame.

The dropouts are completely new, with disc mounts on the chainstays for easier mudguard and rack mounting. Super neat removable V-brake bosses continue unchanged. It's not possible to fit caliper brakes or cantis. Only strong braking options for the Roadrat because drivers are dopey and we like stopping in a hurry.

• Custom butted Cotic Fe Cromoly frame with Ovalform top tube. A mount for everything: Racks, mudguards, discs, v-brakes.
• Cotic designed RB2 fork. Cromoly tapered legs, front right disc mounting for safe management of brake forces and guaranteed clearance for mudguard stays. Now with a disc only option as well as V/disc. Colour matched to your frame.
• Super versatile Dogsbody2 dropouts with solid mech hanger and chainstay disc mount means a bit of what you fancy. Gears, discs, SS, hub gear, fixed, whatever.
• Huge tyre clearance on 700c wheels. Big road or cyclo-cross tyres (up to 46c/1.8"), or how about 29 x 1.75" MTB tyres for the ultimate green lane cruiser? Maybe 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!
• 68mm threaded BB shell with clearance for pretty much any chainset you like. Only super narrow track setups won't fit. Single, Road Standard or Compact, Triple, all good on the Roadrat.
• Optimised flat bar handling and rider fit. No toe overlap, no twitchy handling, no back ache, no worries!

The chart is a guide to frame size for the latest 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 our MTB frames if you're coming over from our 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.

Seatpost diameter: 27.2mm (wise to get a decent length one)

Seatpost clamp: 29.8mm or 30.0mm (bolt up clamp is included)

Bottom Bracket width: 68mm

Headset: 1.125" only
