Hi!  I just bought a City 1.2 bike, which is great, but I'd like to replace the stock handlebar with a riser bar.  Does anyone know the size (thickness) of the stock bar at the stem?  Thanks!


@bikeprof Thanks for reaching out!

The stem size of the Co-op Cycles CTY 1.2 bike is 31.8mm. Often times this is referred to as 'OS' in the name of handlebar, which stands for 'Over Sized'.

Hopefully this helps!
