Bicycle component giant, Shimano, is launching their new 1×8 drivetrain, ESSA. The new affordable drivetrain is geared to target the active, entry-level cyclist. ESSA will be compatible with the current 8-speed flat-bar ACERA, ALTUS, and TOURNEY TX systems.

Engineered with an Essence of Active concept, Shimano Essa is equipped to elevate Shimano’s existing 8-speed lineup. Essa will simplify an often complex set of component groups. Being both versatile and robust, Essa is ready for the next generation of cyclists.

ESSA- The Essence of Active

Shimano says ESSA is ideal for a wide range of casual sport bikes. These types of bikes would include MTB, fitness, and city bikes. The ESSA narrow/wide teeth profile and Dynamic Chain Engagement technology will ensure reliable chain retention while riding the rougher stuff.

The new 1×8 speed system is said to have a 400% wide gear range (11-45T). And the compatibility with Shimano’s current 8-speed Hyperglide systems will make things easier for retailers and cyclists.

  • Optimized geometry and spring retention reduce chain drop
  • Low-profile design is optimized for rough terrain
  • Total capacity: 34t
  • Max low sprocket: 45t
  • Shimano Shadow RD

FC-U2000-1 Front Chainring

Special gear tip shape improves chain engagement and retention for smooth riding over rough terrain.

  • Chainring option: 32t, 40t
  • Dynamic Chain Engagement+ (32t)

CS-HG400-8 Cassette

Wide range 8-speed cassette provides reliable shifting performance for various riding styles.

  • Wide range: 11-45t (11-13-15-18-22-27-35-45)
  • Hyperglide

ESSA branded products will only include the rear derailleur and crank, based on the existing Hyperglide platform, and seamlessly integrate with the existing Shimano branded products in that range.

New CUES Short Reach

Shimano has optimized the ergonomics of the new CUES group that was released last year. The update, called S-Reach, is a shorter reach to activate both the shifter and brake levers throughout the CUES line. This change will be a pleasant change for those riders with smaller hands. This will provide a more comfortable and confident riding experience for all riders.

The new S-Reach shifters are more intuitive and comfortable. They’re equipped with distinctive push/push shifting and two thumb-accessible buttons close to the grip. Thumb travel is reduced by 11% and the two levers are 10 and 12mm closer to the rider.

The new CUES update applies to the brake levers as well, as they bring the lever 20% closer to the handlebar, making stopping easier and building confidence.

Shimano Non-Series Hubs

Riding piggyback on the launch of the Shimano ESSA and the increased diversity of the new updated CUES group, sits a refresh for Shimano’s non-series hubs. Both the front and freehubs will be completely renewed across the entire 11/10/9/8-sp[eed lineup. They will also be concentrated around a simple and easily understood line-up.

The sealing performance of these two hub models will include labyrinth and contact seal bearings – designed to endure extreme torque levels for aggressive trail riding.

QC400 & QC300

This series features contact seals only, while the QC300 series retains traditional cup and cone bearings.

These are designed for reliable eBike use. The FH600 and FH500 Freehubs with Microspline will be compatible with Shimano LinkGlide 11-speed hubs and be easily upgraded from Linkglide to Hyperglide+ 12-speed. This creates peace of mind for riders and mechanics when it comes to any after-service maintenance of the hubs.

Can’t wait for ESSA XTR.

Looks decent, I’d be interested to ride it and compare it to more expensive drivetrains from say 15 years ago.

ESSA is designed to work with MTB, not road.

It’ll work perfectly! ESSA is designed around the historic pull ratio so it’ll work with all non Cues Shimano 7,8,9 and some 10 speed shifters (Not 4700 or RX400) Basically what we Cues should have been.

What does “Engineered with an Essence of Active concept” mean?

It means Shimano needs a copy writer.

Active concept getting is a deliberate, methodical approach to arriving at concepts to address concerns and problems, while passive concept getting allows concepts to emerge naturally..

It looks that Shimano is giving up on cup-and-cone bearings for hubs. That would then be one of reasons for the ESSA new range.

I like cup-and-cones for there ability to withstand axial loads (provided their preloading is adequate). However, from the graphics, it seems that the new ESSA hubs offer a better sealing.

To be noted also, the three different bearing designs of the freewheel bodies. Suprising ! And hard to say which one is the best …

Great to see development at this level. Cues, Essa and Linkglide are the best things from the big 2 drivetrain brands in years.

Anyone reckon this gear will be compatible with retro 90s thumbshifters and 7sp hubs?

I cannot answer your question, but to take a guess.. if your 7sp shifter works with the original 8sp Shimano cassettes then this seems to be the same thing as it. The article states Essa is “based on the existing Hyperglide platform”. I never tried the classic 7sp shifter with an 8sp cassette, but I have a lot of that stuff laying around.

The RD and chainring will work; 8 speed cassette would not fit the hub though..
