Simply put, the Mach 4 SL brought out some of my more destructive XC urges (stomp pedals, throw elbows, win press camp) and I’m not sorry about it.

2018 Pivot Mach 4 goes Boost

Jun 2017 · Saris Mercanti

The Mach 4 is one of those bikes that’s difficult to categorize. With 115mm of suspension on tap, it looks the part of an XC race bike, yet it rolls on 27.5” wheels. For 2017, it’s gone boost and received additional updates. - Mtbr.com
