RPM Diesel 14mm vs 16mm: Which Thickness? (2026)
Last updated: October 2026
Same wide square shape and grit. The 14mm pops more, the 16mm holds the ball longer.
Both RPM Diesels share the same wide, square 16" by 8.25" shape, 5" handle, EPP core and SICmatrix grit.
The 16mm measures 8.7 oz with a swing weight about 121.7; the 14mm should be close. Pick the 14mm for more pop and a crisper response, the 16mm for more dwell and softer resets. Code PRH takes 15% off either at rpmpb.com/PRH.

- 14mm: more pop on drives and counters, a crisper feel, a little less forgiveness on touch shots.
- Weight: close between the two. Both are heavy to swing.

Most players should start with the Diesel 16mm; the extra dwell suits a heavy, stable paddle. Pick the Diesel 14mm if you already play a thin core and want more pace.
