What Our Gearhead® Experts Are Saying:
"This build really impressed me for the price point. The Eagle 70/90 Transmission drivetrain shifts cleanly and holds up well under load, and the Fox Performance suspension keeps the ride efficient without feeling harsh. It climbs quickly, tracks well through technical sections, and feels like a true XC race platform. If you want modern Transmission tech in a more accessible package, this is a smart choice."
When we are lining up for local XC races or pushing the pace on rolling singletrack, the Mach 4 SL V4 Ride Eagle 70/90 Mountain Bike from Pivot delivers the speed and efficiency we expect from a modern cross-country machine. Built around Pivot’s hollow-core carbon frame and dw-link suspension platform, it responds instantly to hard efforts while maintaining traction and composure over roots and chatter. It feels light on the climbs and confident when the trail tightens up.
Fox Performance suspension pairs a 120mm Fox 34 SL fork with a Fox Performance Float rear shock delivering 100mm of rear travel. The SRAM Eagle 70/90 Mechanical Transmission 12-speed drivetrain provides durable, precise shifting with a wide 10-52t range to tackle steep climbs and fast descents. DT Swiss X1900 wheels and Maxxis Ardent Race 29 x 2.2in tires keep acceleration snappy and handling predictable across varied terrain.
Heads up - We do our best to keep bike specs and images current, but occasional component changes can happen without warning-and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearheads are always here to help.
