Finally Deity Cavity 31.8mm Handlebar Stem In Black Bonkers Deal: 40% Off [N7Bg2fmu]

Perfected by deity’s extensive real world testing for over 12 months, the cavity stem was developed with pain staking focus on strength, function and attention to detail. as with all deity products, the cavity stem is no exception to the principals that laid the foundation for a brand relentlessly dedicated to the riders’ experience. built on the promise to deliver what is truly best for Deity's customers and riders regardless of industry trends or ever changing standards, deity has always committed to doing what is optimal for the industry and sport regardless of profit. They believe listening to the athletes who make up our sport is the only true path to success. this philosophy is why they take the time to develop and real world test all our designs so you don’t have to.

The cavity steerer mount stem has become the benchmark by which all deity stems are measured. this beloved no–nonsense design has become a top seller, and for good reason! this shorter 35mm reach version of the original cavity stem was a direct response to the riders’ need for a shorter stem to balance the longer top tube designs of today. this completely hollowed out design removes excess material while utilizing an exoskeletal frame allowing Deity to deliver an incredibly stiff feel with rounded edges for a clean appeal. now a staple in our line, the cavity stem is here to stay!

  • The popular deity cavity stem is now available in a 35mm length!
  • Machined from 6061 t6 aluminum
