Lighter, more affordable and featuring a die-cast magnesium casing.

Pinion was showing their  C Line magnesium-cast gearbox. The C1.12 build has 12-internal gears that have a 600% range with 17% steps in between gears. Pinion's C 1.9xr and C 1.6 have 9 and 6 speeds respectively. This new shell at 450g is 190g lighter than their aluminum case (640g) and it’s far easier to produce. Production time is down to 3 minutes for the die-cast magnesium case compared to 45 minutes for the aluminum shell. This massive production time reduction means the Pinion C1.12 will be more affordable than previous versions. Weight of the full C1.12 system in the video below is about 2kg or 4.5-pounds.

So its about 300 grams lighter than the last P box. I had no issue with gripshift but not shifting under load is an issue they should fix. Shaving $400-600 off the price would help as well.

Being in right Gera all the time and shifting without pedalling far outweighs a slight pause to change gears. You can't shift under load with a mech either and thrash it out if you do. So many positive benefits to the Pinion over a mech. Your subconscious quickly sorts out how and when to shift so it's a non issue.

So go check out the cinq5 Shift:R for the Pinion C-line range which was shown at the tout-terrain booth this year. It's a replacement Shifter-Box with new mechanix and two thumb shifters on each side of the handlebar to shift up to two gears up or down similar to their already available Shift:R Triggers for the Rohloff Speedhub.

Dang, do they have any plans having the gear shifting done electrically?
That would allow even neater package with similar shifters as XT(R) Di2 has...

This or a frankenstein blackbox mating an Eagle shifter to the Pinion gearbox.

I have been completely blown away by the performance of this box. For me there is no downside other than cost. The delay in shifting is non existent. I can sneak a shift at the bottom of a downstroke 95% of the time without pausing and shift way more now than one a regular drivetrain. Being in the right gear all the time and perfect instantaneous shifting and performance is amazing. Centralised weight is awesome. My Taniwha feels lighter than my last bike. Gripshift is no problem. I just love going out and knowing my gearing will be perfect

But Effigear has issues with maybe not enough gear range (460 %, should be okay though), but it only has 9 gears, which means quite large jumps. This is due to a direct 1:1 gearing configuration (there are 9 gear pairs to cover 9 gears), while Pinion uses 2 gear stages (3x6, 3x4 or probably 3x3 gear pair layout for 18, 12 or 9 gears), which means they get 18 gears out of 9 gear pairs.

The other factor, that i have issues with, is that the wheel needs to rotate the gearbox in order to shift in one direction, otherwise you would have to backpedal to release the pins in order to shift. This means only concentric, fixed chainstay length designs are possible, which i don't like particularly...

I have the Effigear gear box for 1 year and half:
not enough gear range: for my enduro and allmountain use, it's not an issue
which means quite large jumps: not an issue too, it's not a road bike
you would have to backpedal to release the pins in order to shift: not necessary to backpedal,just less torque when you pedal is enough
This means only concentric, fixed chainstay length designs are possible, which i don't like particularly...: I agree with the belt, but you can do a different design with a chain and a tensioner

I've actually contacted the guys at Effigear, regarding backpedalling and pins releasing and so on, their bikes don't have a freehub, which enables you to shift without backpedalling, since the chain (or belt) drives the gearbox. If you had a freehub, you'd have to backpedal for the output gears to effectively rotate faster than the input, releasing pins. If you'd use a chain tensioner, you couldn't have a freehub-less rear wheel, which means the chain wouldn't drive the gearbox, which would mean you would have to backpedal. This is straight from the horse's mouth.

Using a tensioner and having no freehub on the rear wheel would do all kinds of wonderful things to the chain (i.e. bunching it up in places you wouldn't want to). Unless you put an immense spring into the tensioner, enough to go down a spring size, if using a coil shock Tongue

Also, regarding the gearing, i'm riding a 1x11 Sram cassette, 420 % is enough, but i still want Eagle for those rare occasions. Regarding the jumps, they are sometimes slightly large on 1x11 on a smaller range and you have people claiming 1x11 has insane jumps (people coming over from the road). But these are irrelevant, since MTB has had ~20 % jumps since 9spd era (the argument was, that 2x10 has better ratios than 1x11, but i disagree, since 1x11 and 1x12 just add sprockets, more or less keeping the same jumps lower down in the cassette, compared to 9spd and 10spd).

In my opinion, the only plus of the Effigear is the possibility of using a trigger shifter. And the layout, enabling you to go high pivot. But there are too many drawbacks, or better yet, limitations.

I like the effigears pivot height better than the pinion, but not a deal breaker.

Not grip shift as you know it. Grip shift is great for a gearbox as you can change lots of gears quickly. I never missshifted in three years running a Pinion. It really is a misconception, try one, you'll see.
