Shimano 2013 Gravity Components – Sea Otter 2012

by Brian Mullin on April 19, 2012

Shimano has been busy lately, and the bleeding edge technology that came out on their XTR wonder child, has been slowly morphing itself into their other groups. The XT group was the initial candidate, then SLX recently got it for 2013, and now the downhill and freeride oriented Saint receives some tidbits of that engineering knowledge. The Saint gets the ICE Technologies for their brakes and the Shadow Plus clutch derailer. Pile on brand new pedals, upgraded hubs, shifters and cranks and you get a highly evolved, light and robust set of components. They have also added the all-new budget minded Zee group, which has the ICE brakes, Shadow derailer, hubs, shifters and cranks.

Shimano Continues Legacy, Leadership in Gravity Components with Two New Groups for 2013
Calif. (April 19, 2012) – Shimano, the gravity component pioneer,
reinforces its leadership in the segment with the introduction of two
new gravity component groups for 2013:
Saint and Zee. Sharing a
similar commitment to speed, these component groups serve aggressive
riders and DH racers a full dose of Shimano’s latest mountain bike
component technology that has changed the trail riding market and is now
poised to define the benchmark for gravity riding performance.

systems engineering means that the latest technologies and features are
seamlessly integrated in braking and drivetrain systems that provide
riders with enhanced control, focus and speed. Shimano Shadow Plus rear
derailleurs improve chain control and reduce noise with new silencing
technologies that let riders focus more on the trail with less
distraction. By reducing heat in the disc brake system, Shimano ICE
Technologies increase braking power and benefit riders with a
controllable and confidence-boosting brake system. For increased focus,
and predictable and confident control, Saint and Zee offer riders two
new keys to unlock the secret of speed.

Totally Re-Designed New Saint Group is Pure Gravity
The original dedicated gravity component line is more focused, more
advanced and more dedicated to speed than ever with the new M820 group
for 2013. The now 10-speed Saint M820 group embraces Shimano’s latest
technology and debuts all-new advancements in both heat control and
drivetrain stability. With new ICE Technologies and Saint’s take on the
Shadow Plus rear derailleur, the M820 group promises riders a pure
riding experience and the gift of focus through seamless and stable bike

  • The new standard in DH rear derailleurs
    – New chain control and silencing technologies in the new RD-M820 are a
    game changer for gravity riding. In addition to the proven Shadow Plus
    RD design, a Saint specific, high durometer urethane bump stopper
    (between the RD and the dropout) was added to reduce impact noise. Now
    10- speed, the new RD-M820 features a durable super wide link that
    serves as the backbone of the DH parallelogram. Ready for track and
    trail, the mode converter easily adapts between two settings for MTB
    cassette gear ratios (11-32, 11-34, 11-36) and road (11-23, 11-25,
  • ICE Technologies even more advanced
    – The new Saint disc brake embraces Shimano ICE Technology and advances
    it, reducing heat and improving performance through multiple combined
    features. In addition to finned brake pads, self insulating ceramic
    pistons and three layer rotor construction, new M820 disc brake systems
    will also see the introduction of a 30mm aluminum banjo fitting and an
    innovative finned rotor, that reduce operating temperatures by
    increasing the convective surface area. The new SM-RT99 Ultimate Clad
    rotor is a significant performance enhancement reducing heat by 50
    degrees, creating 20% more stopping power, eliminating brake fade and
    increasing pad life. A new, longer 30mm banjo fitting extending from the
    caliper further reduces heat at a critical location where oil
    transitions from hose to caliper. Saint shares the excellent ergonomics
    and system stiffness found on Zee brake systems and is also ISPEC
  • Improved shifter ergonomics, easier shifts
    – Advanced DH ergonomics including longer levers (+5mm) and textured
    paddles combine with low friction ball bearings to reduce shifting
    effort on this gravity specific shifter. Designed specifically for
    Shadow Plus and Vivid indexing, these shifting enhancements reduce base
    shifting effort by up to 37%, so that on-trail shift effort is as light
    as ever. Instant, effortless shifts create a whole new paradigm for the
    most durable, gravity-ready drivetrain on the market. Premium functions
    include instant release, multi release and 2-Way release. An I-SPEC
    bracket option will be available to reduce weight and handlebar clutter.
  • Reliable DH race cranks
    – New Saint Hollowtech II cranks are hollow forged Duraluminum,
    creating a lighter weight crank set with an axle that is 250% stronger
    than trail options and an arm that is double strength. The single-only
    setup looks great with custom aluminum hardware and is available in
    three lightweight chainring options (34T/36T/38T) and in two crank sets:
    FC-M820 (68/73mm BB) and FC-M825 (83mm BB) that both offer Presfit BB
    compatibility. A steel pedal insert adds durability at the pedal
    interface. Note: MTB Press fit BB: SM-BB71-41A (50mm chainline; 89.5×41
    BB shell), DH Press fit BB: SM-BB71-41C (58mm chainline; 104.5×41 BB
  • New Saint hubsets
    – New Saint hubs are lighter and easier to adjust. All weather rated
    with top quality sealing, adjustable angular contact bearings, and
    precision ground, integrated cone construction, these hubs track
    straight and roll true. Centerlock mounting for alignment and braking
    efficiency, Saint hubs are available with 20mm axles up front and 12mm
    axles in 135, 142 and 150mm configurations.
  • New wider, lower profile Saint flat pedals
    – After years of success, the crowd favorite DX flat pedals are
    succeeded by new PD-MX80 Saint-branded pedals that feature a wider
    (+3mm), lower profile (-8.5mm) platform with an easy replacement pin
    system. Adapted to modern riding, the PD-MX80 retains the durable,
    smooth rotating axle and concave ergonomic platform that made the MX30 a

Introducing Zee: Gravity Components for a New Generation
Shimano introduces Zee, a new line of gravity components that are an
ideal starting point for aggressive riders and racers. Zee is the
gateway gravity component line that allows riders to get on board with
Shimano’s gravity program and experience premium new component
technologies at a price they can afford. Highlights in the Zee line
include a 10-speed system that
comes standard with new ICE Tech and Shadow Plus technologies.

  • Zee Shadow Plus RD
    – The Zee RD-M640 features Shadow Plus technology proven to reduce
    chain slap, drop and impact noise and the 10-speed short cage RD’s low
    profile tucks safely below the cassette cogs. With two spec options that
    enable a typical MTB cassette (11-32,11-34,11-36) or a close ratio road
    cassette (11-23,11-25,11-28), Zee is ready to handle the needs of
    enduro and DH racers. 10-speed also offers complete compatibility with
    Dyna-Sys MTB product and Shimano’s latest chain and cassette technology.
  • New gravity 10-speed shifter
    – The new Zee shifter uses Dyna-Sys compatible cable stroke, which
    means linear shift effort, easy set-up and accurate, stable gear
    changes. All new paddle shapes with 2-Way release and dimpled main lever
    allow riders to be more in control and perfectly engaged.
  • Powerful 4-piston Disc Brakes with ICE Tech
    – New Zee hydraulic disc brake systems are gravity rated with a
    Servo-Wave brake lever and new 4-piston ceramic disc brake caliper.
    System stiffness is tuned using Shimano’s high-power hose and shorter
    lever blade while ergonomics are perfected with a new pivot location and
    dimpled surface. ICE Tech brake pad and rotor options reduce heat in
    the system and maintain performance on the longest descents.
  • Durable, reinforced crank set
    – The thick wall aluminum construction on the Zee two piece cranks and
    reinforced steel axle translate to additional confidence on the trail.
    With an axle 30% stronger than comparable trail cranks and smooth
    running, accurately aligned chain wheels, the Zee crank will perform
    reliably – run after run. The crank arm features outboard bearings and
    steel pedal inserts. Options include single ring 34T/36T/38T; FC-M640
    68/73mm BB and FC-M645 83mm BB. Pressfit compatible.
  • New durable and reliable hubsets
    – Quick engaging, smooth running hubs are a big advantage on the
    mountain. The new Zee hubs include quality sealing, adjustable angular
    contact bearings, and rotate on extra stiff, one piece rear axles with
    integrated cone construction. Zee hubs are ready for any modern gravity
    bike with 20mm axles up front and 12mm axles in 135, 142 and 150mm
