Frame
Every gram counts when it comes to a race bike. Pivot Cycles manufacturers ensured that the Pivot Mach 4 SL would be ultra-light, weighing an impressive 1845 grams.

You don’t need bearing cups, and this also gives the bike a smoother front-end look. Your bearings will also be protected from any road debris when cycling.
This design also makes servicing the bike much more straightforward.
The carbon frame is durable with plenty of swingarm protection. If you are riding in rough terrain or the woods, it would be ideal for keeping your swingarm safe from impact.
