Shimano introduced their third-generation Saint groupset in the most fitting
setting possible, Whistler Bike Park – a real test for any gravity oriented
On the kickoff
morning of Shimano’s Saint M820 media camp, Aaron Gwin took his second World Cup downhill win of the 2012 season – on the new Saint group. It was quite an
impressive way for Shimano to make their first impressions to the press, especially considering
that M820 has been redesigned to cater to gravity racers first.
So, good enough for
Gwin, good enough for us, right? Unfortunately, the groupset as a whole wasn’t quite ready for us to try, due to delays in chainguide and rotor production. However, despite a couple of glitches, our initial experience proved the revamped, downhill-specific groupset has the same potential for regular gravity riders as it does for Shimano’s elite level racers and freeriders.
Shimano’s development process for Saint has been impressive – the M820’s release was put on hold for a year so that Aaron Gwin could give feedback and win a gang of World Cups on prototypes. But, as always, the true test is what happens out on
Bike parks such as Whistler are hard on bikes and components because of the relentless
downhill terrain and the sheer number of miles you
can rack up in a matter of days.
Over the course
of our testing, we did experience some
unexpected issues with the new M820 Saint – a noisy B-knuckle, inconsistent
brake lever feel and a bent pedal spindle.
The bikes used at the camp varied hugely. Rentals provided by Shimano included Norco Aurums as well as Trek’s highly acclaimed Session 9.9 carbon, as piloted by Gwin, and some journalists had shipped out personal bikes. This meant a variety of different mech hangers and pivot
locations needed to be considered during mech setup.
impressions of the new Shadow Plus Saint mech were good. The clutch-style system employed to tension the cage and reduce
chain slap lowered noise hugely, leaving us hammering rough lines in stealthy fashion.
The switch for the Shadow Plus clutch on the new Saint
As the first
day progressed though, many of the bikes began to start banging and
knocking due to the derailleur B-knuckle contacting the bottom of the
chainstay. Some gave a constant tapping while others only sounded on more severe hits. Shimano’s tech team remedied this very quickly
though, making some minor adjustments to the B-tension screw and adding more
tension to the Shadow Plus system after its initial bedding-in period.
runs had us free of chain slap and, on most frame designs, completely free of B-knuckle knocks. For those that did still experience some contact, it was
only on the biggest of hits. Shifting remained consistent and precise,
even when we were slamming through the gears on the bumpiest trails.
From the first
pedal stroke, we knew that Shimano had nailed the rider compartment
ergonomics of the group. They claim a 37 percent reduction in effort on the
thumb lever and our experience supported that statement – it was noticeably easier. Shifting
remained crisp, positive and, most significantly, lighter throughout our test
period. Shimano have achieved this by using the Dyna-Sys design and a
lever that’s 6 percent longer.
The cable release trigger is a whopping 10
percent longer. Although the improvement in feel isn’t quite as striking as that from the
thumb lever, it’s still easy to actuate and seems to resist misshifting over
rough terrain should you rest your finger on the lever or go for a gear while
blasting over bumps. We were thoroughly impressed by this feature.
We liked the
brake lever ergonomics. Once actuated, the light yet powerful feel we’ve
become accustomed to courtesy of the latest XTR Trail brake is present and correct.
The right brake and shifter in tandem
In an attempt to set
a rider up for one-finger braking, though, Shimano have lost some of their range of adjustment.
Our smaller hand size barely put us into the usable range of the lever’s reach
adjuster. And because the lever is so short, there wasn’t much we could do about it.
While we were
able to achieve our ideal initial setup by bottoming out the reach adjuster,
that led to the most serious problem of our test – inconsistent brake lever
feel. In the end, we were putting the
Servo-Wave mechanical leverage adjustment at its highest point, which
gave a mushy feel and seemed to open the lever up to additional sensitivity and
the need for a perfect bleed.
The Saint’s brake performance was mind-blowing in terms of both power and modulation, but we experienced regular issues with brake pump on one set of
sample stoppers. On long bouts
of constant braking – anything up to two minutes or so – our levers would pump up and push out a noticeable amount. A quick release of
the lever would reset its contact point, until the next bout of
Shimano’s on-site techs attributed the change to
air caught in the lines, and made three bleed attempts before having to swap the brake out. They then bled that brake. They didn’t, however, do a ‘vacuum’ bleed, which they did suggest at one point. That said, on
our other set of sample brakes, we only experienced brake pump once, on the
rear, while riding one of Whistler’s more extreme trails.
three-day test period we did our best to give Shimano the benefit of the doubt,
as many of the Saint parts arrived just hours before the camp began. The
three-man crew led by Shimano Canada’s head tech, Ben Pye, worked until
3am the night before test day to get everything ready.
However, a rushed
brake bleed can be excused once or twice, but three times with two different
brakes is pushing it. We must stress that this probably wasn’t the techs’ fault, either, as the camp also served as their introduction to the group – it’s excusable that they might not have had the intricacies of the new parts
completely nailed. Nonetheless, we left the camp with the unresolved issue on one set of brakes.
Back to the
modulation, then. After receiving rider feedback from some of their top
athletes, Shimano wanted to increase the amount of modulation on offer and
remove the more on-off feel the older Saint brake gave. Power is now delivered in
a far more controlled fashion – great for steep technical descents.
feel certainly took time to adjust to, and opinion is still divided as to whether we prefer the more punchy feel of the older
Saint brake. Regardless, the control is impressive.
The new Saint
PD-MX80 pedal stands out as one of the highlights of the groupset. Although one tester managed to bend a pedal, it’s worth bearing in mind
just how extreme the terrain and impact forces were. All our other samples made it through the test days unscathed, despite
numerous pedal-to-rock incidents.
Performance was impressive. The platform is 3mm wider and 8mm thinner than on the
previous DX pedal, but the real story comes from the excellent steel pins on
the MX80. They’re adjustable in height (via washers) and, thanks
to the well-positioned nine pins per side, grip is excellent. Bearings appear to be of XTR or Saint quality and smoothness standards.
from the freak failure, we came away very happy with the riding performance of
Saint’s new flats.
It was no real
surprise to experience the same flawless performance from the new Saint cranks as we enjoyed on the old. Stiffness and strength are still hard
to beat, and it’s hard to fault the straightforward, zero-faff fitting

Our only gripe (and it’s barely worth mentioning) is with the aesthetics.
Although initially striking, get the cranks turning and a Five Ten rubbing and
the graphics are soon worn away. We’d love to see a
polished face, just as the XTR cranks offer.
The new Saint hubs
are said to be lighter, and now come in a 12x142mm standard to accompany the
12x150mm axle length. We had no real performance issues with them, but
will be testing them over a longer period before reporting back with the full
Unfortunately, we were unable to ride the new chainguide and Ice Tech rotors, with their finned aluminium cores. As soon as test samples arrive, we’ll
be sure to get them straight onto our bikes for some long-term trials. We’ll also bang out a load more runs on the brakes before
offering our final opinion and verdict, so stay tuned.
