My first mountain bike was all steel, had eight  gears in the back, three up front, and no suspension. It also had 26" wheels. That was in 1987. The next year, I was riding a bike that was half-carbon, half-aluminum, had a 2.5 inch house-brand front suspension, and weighed 4 lbs. less. By 1995 I had purchased an early dual-suspension Trek Y-bike, and by the time I pretty much quit racing in 2001, I had a titanium frame with a soft-rear suspension, 3 inches of travel up front, and one of the first PowerTap MTB hubs ever built.

Now, I'm riding a 2012 Trek SuperFly 100, with 4 inches of travel up front and in the rear, hydraulic disc brakes, two rings up front and ten in the rear. The wheels are 29 inches in diameter. THE NEXT YEAR, SRAM and then Shimano, introduced Single-Ring front drivetrains, 11 gears in the back, with broader ranges than I'd ever seen before. I think front and rear suspension gains a technology flip EVERY TWO YEARS! My own rig (and that of my wife), now has an OBSOLETE front and rear suspension system, a rear linkage system that has not been used since 2013, and the tires are 3/4 of an inch TOO NARROW.

It's incredible. Technology has literally transformed mountain biking. It's safer, faster, more comfortable, and higher performing than I've ever seen before.

BUT IT STILL TAKES SOMEONE WITH AN ENGINEERING DOCTORATE TO EXPLAIN SUSPENSION TO ME! AAAUUUGGHHH!

Enter the ShockWiz, by SRAM. It's two little boxes that mount to your frame and fork, and then attach to the compression air ports, where they measure impact, rebound, and all sorts of things that I just can't explain. I'll let it do the work.

The ShockWiz started out as a GoFundMe project, and is the brainchild of an Australian mountain biker. It started out around 2014, if I recall correctly, and ended up going to market after SRAM and Quarq saw the opportunity, bought the concept, and got it to the finish line. I was a fascinated early investor, but sadly, my opportunity to do some REAL mountain biking, is usually limited to 3 or 4 days a year. I don't compete, but when I'm out there, I love the challenge of every corner, every tree, every root, every rock garden, and every climb and descent. But I'm absolutely convinced that if I KNEW how to properly tune my suspension, I could improve my confidence, my competence, and the joy would compel me to do the simplest thing I can do - RIDE MORE OFTEN. I am convinced that the ShockWiz is doing that, right now.

I'm writing this from a remote fishing village in Arkansas that sits along the famous "Wombly Trail". It's almost 40 miles of singletrack along the Ouachita River, and for me, it's Heaven! But it's also a PERFECT place to put the ShockWiz to use, and I did that today.

My 2012 SID Air was the first component to get the treatment, and it started with a roughly 15-minute calibration procedure that allowed the ShockWiz app to figure out my baselines. I used a shock pump to set the manufacturer's recommendations for the upper and lower chambers into the fork (as well as the rear shock), and then took off on my ride, with my wife not far behind. Over the course of the next twenty minutes, we rode, and when we pulled over for our first break, I consulted the app, which was reading the data behind-the-scenes, the entire time. It gave me recommendations for compression, rebound, ramp rate, preload.... all that stuff that is a mystery to me.
