Today I'd like to talk about why I use the products I use. My only sponsor (and an unofficial one at that) is my employer, Trek Bicycle Corporation.
Regardless, they do make amazingly well thought-out saddles:
The Bontrager inForm. I ride a medium RXL on the road,and a large RL offroad. The lighter foam density on the RL is better for bumpy dirt rides. Now, this is a road-rated saddle, and has some fangs on the back, so it's not ideally suited for off-road use. However, there is a mountain bike version on the way that I've been testing for a few months, and it is the most comfortable MTB saddle I've ever ridden. Hands down.
For pedals, I ride Shimano XTR. They're not the lightest, but I can bash them on rocks all I want and they don't break. I actually chipped a football-sized rock while knocking it out of the ground and the pedal remained intact. I spent some time in the air, and then some in the brush, but the pedals were just fine. If the pedals were the unstoppable force, I would say the rock reconsidered its role as the immovable object.
My drivetrain consists of a Shimano XTR crank, cassette, and front derailleur, SRAM X.O shifters and rear derailleur, and SRAM PC-991 chain. Coincidentally, the Fisher Procaliber had my ideal drivetrain setup when I was shopping. This was before XX came out, and before Top Fuel 9.9s came stock with the compact 20-speed option.
I use Fox suspension because it's smooth, stiff, and light enough. I also like the tuning and Propedal features. My Procal has a 32 RLC up front, with an RP23 in back. Depending on the course I'll use the different propedal settings. Learn your suspension: it makes a difference.
I'm mentioned two contact points, but the remaining two are the two about which I am the most particular: the grips, and where the bike contacts the ground.
For grips: I love ESI chunkies. They're light, comfy, and fairly durable. And they have a lot of grip, which is good when the name of a product is a quality it is supposed to have.
And tires: tires are a talk for another day.
