This is the situation. I have GT Agressor 1.0 mountain bike. I want to travel for about a week on my bike, which means that I will have to ride a lot on paved roads (around 70% of the road). So I would like to make the proper adjustments on my GT to improve my speed and make it lighter. Once I come back I'd like to recover my mountain bike. One additional point that is worth mentioning: to buy another bicycle for that specific purpose is not an option.
Said that, the question would be: how can I (temporarily) convert my mountain bike into a touring bike?
Thanks in advance.
