Handlebar clamp size

[denwyn]

On the off chance does anyone know the clamp size of handlebars on a Woos CD sport. It looks about 32 ish mm to me, want to replace the original flat bars with something a bit more comfortable.

Ive been in the same situation with a bad back, recently diagnosed as a bulging disc.
So I have done quite some research !
On my Cube I fitted a really short stem, something like this http://www.ebay.co.uk/itm/161743652459?_trksid=p2057872.m2749.l2649&var=460720171174&ssPageName=STRK:MEBIDX:IT
Along with a 3"rise handlebar

If I'd seen these first I probably would be using them, Trekking bars, 31.8 clamp dia,
a little higher and more swept back than high MTB bars

Clamp reducers will allow you to fit 24.5mm bars and give you more choice.

Then you could go mad, I have fitted these to my non pedelec and sit bolt upright for a totally relaxed ride.

With a bit of surfing theres quite a lot to chose from, here's a bargain ( only if they meet your requirements). (25.4 clamp)

your clamp size is 1" 1/8. Handlebars with diameter 31.8mm will fit.
