I apoligize if this post should not be placed here.. Anyway, the stock crankset and bottom bracket i have keeps comming loose, and when i stand up and put my weight on them they flex. The set i have been looking at is the RaceFace Atlas.. I am just getting back into riding from many many years. I am a bigger rider and like the all mountain rides. I dont want to have to worry about breaking the set but i want them to be light as they can be for a heavy rider. sorry for the long drawn out post, but is that my best option? I cant spend more then the price for the RaceFace Atlas. thanks for any help.
