iO- A fast moving moon of Jupiter

Now in its second iteration, the NorthRoad iO is a fast, lightweight carbon road bike with fully integrated cabling and provides the perfect frame to build up for racing or just having fun whilst looking pro. We’re not here to judge.

A stiff but forgiving carbon layup

Stiff and forgiving? Yes, due to the sensible layup we’ve created an oversized bottom bracket shell and robust chainstays that help provide immediate acceleration and great feedback on tracking, whilst the seatstays and comfortable clearance for 30c tyres means that you won’t be battered if you’re riding on anything other than perfect asphalt. 

As aggressive as you need

We build our iOs up with plenty of stack height, so you don’t have to be a racing snake to enjoy a fast aero machine. If you would like it slammed instead, just ask. Either way, the integrated stem and handlebars are mechanic friendly and your local bike shop will be able to easily cut your steerer tube down if you ever need.
