Can I raise these handlebars?
Hello all. I just bought this used Cannondale and I'd like to raise the handlebars around 1 or 2 inches to sit slightly more upright while riding. I'm a novice with bike mechanics but looking to learn. Looking at the pictures here can I raise the stem by adding spacers to the steerer tube (and where do I get the correct spacers?) or is this as high as the steerer tube will go (as I suspect because there's no more of it over the stem) meaning I need to buy a new tube/neck?
edit/ I'm not allowed to post images since I'm new, so I'm describing the image which seems ridiculous but I need answers! The stem attaches to the top of the steerer tube at the very top of the tube. There's no additional tube jutting up above where the stem connects. Does that mean that if I want to raise the handlebars I need a longer tube? Or could I buy an angled stem? Thanks.
