Hello everyone

I am considering to buy a Canyon-MTB. Mostly I will be doing non-technical uphills in order to build and strengthen my muscles, so I need something light. I narrowed my list down to the following models:

Exceed Cf SLX 8.9
Grand Canyon Cf SL 8.9
Exceed Cf SLX 9.9

I would appreciate If somebody could tell me which bike fits my requirements better.
