    FRAME AND FORK PACKAGE

The ROADRAT is our take on something fast. But fast wasn't enough. It needed to be versatile, and it needed to be something we felt right at home on at all times.

We started with our award winning Ultra Compact Geometry, but optimised around flat bars and road riding, and we stuck with steel, using 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. V-brake and disc mounts are fitted, because drivers are dopey and we like stopping in a hurry. Add in 700c wheels because they're fast, fun and the tool of choice for covering the miles.

Flat bar model: Long, low slung top tubes means no toe overlap or standover problems, and because of where the rider is positioned, mountain bikers used to central weight distribution and whipcrack singletrack handling will feel right at home.

NEW Drop bar model: Shorter top tube allows the use of drops with normal length stems. Now there's a ROADRAT with more traditional geometry for the non-mountain bikers, or anyone who wants "a proper" road bike with all the ROADRAT's flexibility.

Cotic designed 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 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.

Includes Cotic designed ROADHOG fork in the price.

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.

ROADRAT Complete Bikes are Back!

The ROADRAT complete bike option is back, and better than ever. There have been a few improvements since last year, most notably the wheels, which now feature cartridge bearing disc hubs on Bontrager's top of the range road rims. Light, tough and disc ready - perfect for such a versatile frame. Take a look here for the complete bike specs.

We've also added a drop bar build to the line to go with our new short length frame sizes. These will feature the same basic spec as the flat bar bikes, but with Bontrager Variable Radius drop bars and Dia Compe Mini V brakes. Take a look here for the complete bike specs.

Finally, by doing some better deals with our suppliers we've managed to bring the price down to What more could you want?
