umm pedals are Wellgo LU-313, boron axles
and as for riding shoes well i just started getting into riding and just ride with watever shoes i have in me cupboard.
and do u mean just not be tense when riding over bumps so the bike will float over them more? and use my legs to absorb the impact ?
you need to try to stay loose when you ride but in control its quite hard to explain, but you will understand the more you ride, when you ride you need to act as your body not only controls the bike but that they act like another suspension system on the bike. instead of hitting rocks hard try let the bike stay a bit looser and alow your arms and legs to act as suspension.
i dont really know how to give a good explaination of this mabey someone else will know how better, but riding it basically all about flow, been loose, and riding with the track and the bike as a flowing force not against each other.
remember loose but incontrol so help the bike guide over the rocks and know where thebike is at all times, you dont want to go out there and be so loose yoru out of control you will end up falling off, so you need to find that netural position between loose and control.
as for the shoes get some 5.10's your shoes will feel like there glued to the pedals.
loose is basically dont ride tense and just try stay relaxed and allow you to ride with the forces instead of against them, this should allow for a smoother ride and ussually ends up in a faster time.
