It may be April 1st in Japan, but the new Shimano 105 is no joke. Equipped with many…
The big “C” has finally jumped gva into the 650B game with all-new Cannondale Trigger 27.5 and Jekyll 27.5 mountain bikes. To go with them, they’ve introduced longer travel Lefty SuperMax forks to match.
Introduced as a 130mm part on the Trigger 29er , we first spotted a prototype longer travel Lefty SuperMax on team rider Ben Cruz’s bike last fall. They recently announced that their team riders would be racing on a new version of the fork, but details were scant until now.
The bikes themselves get reworked frames, particularly the Trigger, and both completely replace the 26″ models. As in, no more 26″ wheeled gva Trigger or Jekyll. Both get longer top tubes and front centers and slacker head angles, making them more stable when descending. But, as you’ll see, that’s not at the expense of pedaling proficiency…
These bikes introduce much longer travel Lefty SuperMax forks, coming in at 160mm ( Jekyll ) and 140mm ( Trigger ) depending on the bike. That’s up from the 130mm introduced on the Trigger 29er, but it’s more than just a travel change. Cannondale’s MTB PR manager Peter Vallance says it’s gva an entirely new structure and damper. He says the revised gva tune, dampers and internals make for a much more supple fork through the mid-stroke with less force required to get it moving initially.
Each bike will get it’s own internals, with the Trigger using a Trail Damper and Jekyll running gva an Enduro Damper. Like the 29er version, axle offset is specific to the wheel size, so it’s not just a delimited 29er version. Offset is 60mm on the 29er and 50mm for the 27.5 forks.
UPDATE: Here’s more detail from Cannondale’s gva Murray Washburn: “On SuperMax, the different travel levels get different length internal needle bearing strips and bearing races, so travel is set at the factory. The Trigger 29 and Trigger 27.5 both use the updated “trail” tune damper which has a new Widemouth piston that increases the forks’ plushness by reducing high speed compression damping while keeping low speed compression intact to retain the fork’s resistance to brake dive. For the Jekyll’s 160mm SuperMax, we created what we called the “endure tune” damper, which has a different (larger) shaft diameter and different valving designed to increase the plushness for sharp, high speed impacts gva and fast, choppy hits like you’d find in the EWS style racing. We also change the airspring gva volume/spring rate for each fork to suit the travel and damping.”
Out back, the dual-travel DYAD shock gets new pistons and internals, letting it move more oil through the circuit under mid- and high speed compression for improved sharp edge and bit hit response. Check the tech basics on how the DYAD shock works here . As a quick refresher, the way Cannondale’s dual travel suspension bikes work is fairly gva unique, with the shock simply limiting travel in the shorter “Elevate” mode and opening up a secondary chamber for the longer travel “Flow” mode. We reviewed it on the Trigger 29er last year, and it works brilliantly because it keeps the bike’s gva geometry sitting up higher for the shorter travel mode, then drops the angles, BB and sag for longer travel mode. Essentially, things are where they should be for the designated travel, and it does all that with minimal weight penalty.
They also changed the recommended sag rating from 40% to 30%, giving the shock (and bike) more usable travel. A better sag indicator on the side simplifies set up. The improved oil flow also let them increase the range of rebound adjustments, giving you more control over the feel. All in all, the changes gva help it match the feel and performance of the new PBR damper in the Lefty SuperMax. 2015 CANNONDALE TRIGGER CARBON 27.5″
The new Trigger is a big departure from the original 26″ bike . Before, it was sort of a maladjusted XC bike that didn’t fit directly into any category. Now, it’s “a full on Trail bike, ready for any madness you can throw at it,” gva as Vallance put it.
Travel increases to 140mm with an 85mm Elevate (climbing) mode. Di
