What Our Gearhead® Experts Are Saying:
"I’ve ridden this build hard on fast XC tracks and technical singletrack, and it feels incredibly efficient without being harsh. The X0 Eagle Transmission shifts flawlessly under load, and the Fox Factory suspension keeps it composed when the course gets rough. It’s light, precise, and ready to race straight out of the box. If you want a no-compromise cross-country setup with modern capability, this is it."
When we are chasing podium spots or pushing the pace on our favorite after-work loop, the Mach 4 SL V4 Pro X0 T-Type Mountain Bike from Pivot delivers explosive speed with refined control. Built around Pivot’s hollow-core carbon frame and dw-link suspension layout, this race-focused machine responds instantly to every pedal stroke while staying calm through technical terrain. It feels sharp on climbs, planted in corners, and confident when the trail opens up.
The Fox Factory 34 Step-Cast fork paired with the Fox Factory Float rear shock delivers 120mm front and 100mm rear travel for modern XC capability. SRAM’s X0 Eagle Transmission drivetrain provides precise, direct-mount shifting under power, while the DT Swiss XR1700 wheelset keeps acceleration quick and handling responsive. Maxxis Rekon Race tires in a 29 x 2.4in configuration balance rolling speed and traction, giving us the confidence to attack varied terrain without hesitation.
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.
