Handle Bar Rising

degsy46

I have a Triban 5 which I'm mostly happy with, but I was wondering if you can raise the bars slightly. I've seen spacers you can buy which fit on the stem. Is this possible for my or any bike, as anybody tried this. I have already tilted the bars up slightly and this made a massive difference to comfort.

have you flipped the stem?

You can get spacers to raise the stem a bit, I don't know if the T5 has this?
