Hello Vital MTB Visitor,
We’re conducting a survey and would appreciate your input. Your answers will help Vital and the MTB industry better understand what riders like you want. Survey results will be used to recognize top brands. Make your voice heard!
Five lucky people will be selected at random to win a Vital MTB t-shirt.
Thanks in advance,

Let’s talk about DH bikes. Which brands do you think will release an update of their bike or even release a new DH bike?
Here are my thoughts:
- Trek: an update of the Session is long overdue in my view. The geometry is outdated and they do not offer a version with mixed wheel sizes. Someone in this forum was talking about a high-pivot speed machine...let’s see. The Slash has been updated already this year, next up the Session?
- Commencal: I heard rumors about an update of their mullet DH bike the Supreme DH 29-27. Maybe a shorter wheelbase/chainstay?
- YT: no mixed wheel size option...bit surprised to see them falling behind the curve. The Tues has been updated in 2018, so maybe we will get an update next year or in 2022. They will provide first release a new version of the Capra.
- Intense: will they release the new DH bike which is currently ridden by the factory team next year already?
- Specialized, Canyon, Scott, Mondraker and Cube all have revised their bikes only recently, so I do not expect them to release an update in this category.
What are your thoughts on this topic? Do you have any insights?

but it limits suspension design.. Nevermind
but its heavy... wait 39lbs?..... Nevermind
It will ruin the aesthetic... er.... Nevermind
We just don't want to commit to it? Bingo

Idler gears are what is used as a solution, and while I haven't ridden one yet (so sad...), I don't think it is the correct solution. Just by the way the cain is loaded, they are bound to be noisy (as all the reviewers say they are) and could cause unwanted chain wear as well. The main chainring just needs to be moved higher up, for which a gearbox is the ideal solution.
That means we need a paradigm shift from Sram/Shimano (realistically Shimano, as I don't see Sram pulling the industry the gearbox way on their own) and at the same time a paradigm shift of bike design towards high pivots.
High pivots are the solution, as with increasing wheel sizes the axle paths have become more and more forward to achieve the correct antisquat and more importantly pedal kickback values (because you start above the BB with the rear axle, the 'swingarm' rotates forwards, while it does backwards and mostly upwards if you start below the BB, as with a 26" bike). That and squeezing 29" wheels under the seat at full squish is also an issue (case in point, bent seat tubes), which is negated with the use of higher pivots (rearward axle path), which is also something that wasn't present with 26" bikes.
must be close to release
While shifting on the Pinion requires releasing the pressure on pedals, it requires so just because you aren't able to pull the mechanism to another gear. Supposedly they shift the gearboxes under full power on the end of line check in their production, but they do so with a powerful motor, that has the force needed to move the shifting mechanism. With Effigear the mechanism is shaped in such a way that it gets locked into the current gear under power. Shifting to a faster gear is not a problem, as the new gear pulls the mechanism 'out' of the old one, but shifting to a slower gear is an issue as the current gear locks the mechanism. To release the current gear, the mechanism needs to be released.
With the original design of a concentric pivot and a rear hub with no freehub the speed of the bike did this as you let up on the pedals - the movement of the bike rotated the gear inside the gearbox away from the mechanism (just like the hub needs to rotate faster than the cassette for the freehub to disengage). This means that if you use a freehub on the rear hub, you need to backpedal to shift to a slower gear. Originally, with concentric pivots, this wasn't needed, but that means running only single pivot designs. Cavaliere now has a horst link design with a freehub rear hub, so you apparently need to backpedal to shift.
All this info comes directly from Effigear, the locked mechanism info is old from before the horst link Cavaliere bikes (I was asking because the possibility of such a design was interesting), but they recently told me the shifting mechanism has not been changed, so I'm basing these claims on those two informations that they have given me.

The tire was supposed to be off embargo 2+ months ago.
Assumption is that Maxxis production swamped because of bike boom and has to meet OEM customer demands first and foremost so has pushed all production to tires that OEMs need. The new Shortys are more of an Aftermarket product and haven't been released so I'm assuming they have been put on the back burner for now.
But they've put this photo on their website for a reason )))
It just means, that the fifth one coming soon
