Two decades of mountain bike evolution got me riding again

The technology improvements upgraded my attitude. Mountain biking transformed from an activity I felt I ought to enjoy into a sport I really, really want to do every day. That's good news for a middle-aged man who spends an awful lot of time parked behind a computer screen.To get more news about carbon mtb rim, you can visit zpebicycle official website.

There are lessons here for anyone who's irritated that it's difficult to tell the difference between last year's $1,500 flagship smartphone and this year's replacement. First, don't underestimate the power of steady, incremental improvements like those that revolutionized my mountain bike. Second, technology done well can still bring joy.

And a little joy is just what I needed. The COVID-19 pandemic is an inexhaustible source of anxiety. I'm not alone. A coronavirus-induced bike buying spree has drained inventory around the country, but at my fifth bike shop I found a pair of Trek Fuel EX bikes for my son and me.Full suspension. Enormous energy has gone into fitting formerly rigid bike frames with shock absorbers for both the front and rear wheels. Early full-suspension bikes had serious problems when braking or pedaling, but advancements in areas like pivots and rebound damping in the shocks make it great now. I knew it would be useful on fast downhills, but full suspension helps on uphills, too; the rear wheel tracks the ground contours better, and hitting a rock with the front wheel doesn't lurch you to a stop.
29-inch wheels. When I got started, 26-inch wheels were the only option for mountain biking. Bike designers have since adapted bike frame geometry to the larger 29-inch diameter that means wheels roll more smoothly over gaps and over rocks. With the larger wheels, a bigger patch of rubber contacts the ground for better traction, too. It's worth the extra weight.
Old-style caliper brakes that squeezed the wheel rim have nothing like the stopping power of disc brakes, which use small brake pads to grip a metal rotor near the wheel's hub. My first mountain bike's brake lever had room for all four fingers, but I rarely use more than one finger for hydraulic brakes. And they don't fade nearly as badly on long descents.
Fatter tires. My 1990s tires were 1.9 inches wide, but engineers have figured out how to squeeze in wider ones. My bike's 2.6-inch tires are better at gripping the trail and floating over loose dirt and sand. Given how big my new wheels are, I've been impressed they're not too much heavier.
Dropper posts. A small lever next to my handlebar grip lets me lower my seat while riding for better control on downhills. That comes in handy during my favorite, technical descents with lots of obstacles and careful steering. Pushing the lever while standing up, a compressed air chamber pops the seat back up to the perfect height for pedaling. It's really valuable for adapting the bike to variable trail conditions.
Cars don't use inner tubes anymore, and bikes have followed suit with new airtight rims. The approach avoids pinch flats that could deflate your tire after banging hard into a rock. I've had two punctures so far with tubeless tires, but neither was a problem: Sealant inside the tire quickly patched the holes.
1x12 gearing. Earlier bikes used two derailleurs to place the chain for the best gearing -- the rear derailleur for the rear wheel gears and the front derailleur for the gears near the pedals. Now there's only one gear up front and an astounding 12 in back. That's simpler and gives better clearance when riding over logs. (Cost and battery limits mean wireless, electronic bike shifting isn't mainstream, but it's got potential.)
