Raising handlebars on a threadless stem...
Hey, folks. Hope you'll forgive me for being a newb to this, but I have a question about my Diamondback Sorrento I got from my brother for cheap. I got a tune up and had the derailleur replaced. After riding it a couple times, I noticed that on the roads the handlebars were too low causing my back some discomfort. However, on trails I didn't notice this as much if at all. I looked into it, and unfortunately there's no simple solution to quickly raise the handlebars to a more comfortable position for road riding. I suppose the term for the system I have is a threadless stem
... I did some googling (yes, it's a word!) and saw some people discussing adjusting adjustable stems
... will these work well in giving me more height, and will it stand up to both road and trail use? If so, how do I figure out which one will work for my bike?
Also, will I potentially have to get longer brake cables and how much of a pain in the arse would this be to do myself?
Thanks for tolerating my idiot questions, guys.
Here are some pictures of the setup...
