Designed for touring and travelling how you want to go.

Fully loaded for an expedition, with less luggage to explore less well travelled roads or tracks or with no luggage at all just to enjoy the countryside. The 1779 will transport you effortlessly where you want to take it and handle the type of terrain lesser bikes will struggle with. At home on tarmac, rough roads, tracks and trails. Enabling you to bridge the county, country, continent or the world.

The standard frame is designed with 'Polydrops' that enable either hub gears (with chain or belt drive) or derailleurs to be fitted. In fact, if you want, the one frame that can take both by switching the rear dropout inserts as long as you specify that's what you want, then we can ensure all the relevant cable guides are in place. The frame can also be specified with a Pinion gear box to give you smooth reliable and virtually maintenance free transmission.

How did it get its model number?

Named after the year that the world's first iron bridge was built bridging the River Severn and joining the communities of Broseley and Madeley. The settlement that grew around the northern end of the bridge become known as Ironbridge. Bridges allow you to join many things and bringing communities closer together. Overcoming barriers, allowing you to meet new people and explore new places easily.
