Adam Dwrote a review of Pivot Mach 4 Carbon Mountain Bike Frame - 2015 on March 27, 2015
Familiarity: I've put it through the wringer
I've been on the Mach 4 3 times now, and every time I'm blown away. The 27.5" wheels with 115mm of travel feels much deeper yet rides like a rocket ship. Instant acceleration, unlimited traction, and a stiff yet smooth ride are what stands out most to me. It rides like a 125/130 travel bike but when but with XTR to 22lbs, it makes me want to pick up ST/XC racing again. The funny thing I noticed when riding with others is that people on the Mach 4 would fall way off the back, only to come FLYING back up the trail. It was so fast, it wasn't fun in the group so we kept sagging then racing to the group intentionally.
This bike feels like the acceleration of the Ibis SL-R but with the suspension/ride quality of the SB5c. The traction is like nothing else, not even the 29ers I've ridden. Well done Pivot, well done.
