Which Durometer Tuning Is Right For Me?

In fingerboarding, "durometer" means hardness. A lower durometer number means the product has a softer feeling, and higher durometers mean the product has a harder and firmer feeling.

The Pro Duro Bubble Bushings and O-Rings are available in 3 different durometers (hardnesses):

51A Durometer: Great for those who prefer a super loose feel - The most responsive tuning offered with maximum truck movement and range.

61A Durometer: Great for all ability levels - Very responsive – Allow for extreme truck movement and range.

71A Durometer: Great for those who prefer a tighter feel that allows for crisper movement and tricks - Provide a moderate amount of truck movement and range.
