- Carbon gearbox full sus? Zerode Taniwha!

Nothing wrong with grip shift, especially when you have 12 gears to play with that don’t need pedal revolutions to change gear.
how many degrees will I be rotating my hand through to achieve that? Having to adjust my hand position to change gears is still a big nope for me.Posted 3 years agoneilforrowMember
Looking at it a bit further, the gripshit is a downside IMO. But would accept it is the box worked well.
Disappointed at the loss of the high pivot type suspension layout, but as Rob notes in the vid, there are + and – for that.
He keeps talking about target weight / how light it is but doesn’t actually give it for that build. It’ll be interesting to see how it comes out.
I’d love to try one.Posted 3 years ago
I’d love to try one too. To see if the constant chainline and low rear wheel weight can really be felt.
From a non-buyer pov I would have liked to see the high pivot remain – just to see someone trying something different.
Would have looked amazing if the chain tensioner could have been removed. I’ve never ridden a concentric bb pivot though to compare.Posted 3 years ago

As many degrees as you want? To change 1-2 gears you don’t need to drop your wrist, just roll thumb and forefinger knuckle. To move 3 you might need to dip the wrist a little but its the same as you have to stretch your thumb to change 3 gears on a trigger-shifter. To move more well you can either move your wrist a whole chunk to get 7 or 8 or even the whole 12 if your not on tech terrain, like at the end of a run and dropping all the gears to cruise a fire-road, or having just stopped in the wrong gear and starting again. But mid-tech you just repeat the 3 gear move you would with a normal shifter, its dead easy and you can even do it while braking, just like how your thumb is not holding the bar when your changing gear with a trigger.Posted 3 years agostewartcSubscriber
I think gearboxes are the future and we are seeing them getting smaller and lighter, the question being will SRAM or Shimano take up the baton and put their considerable resources behind the development of lighter, reliable and affordable components, I fear that in the short term it will be no?Posted 3 years ago
reach, not top tube length. id say its bob on with the majority of current bikes?
Reach is the most important reference in frame length now. Gives length from BB centre to steerer-tube centre, I think.
Once you know what length reach suits you, it’s remarkably accurate at predicting how well a bike will fit. Compared to going off ETT, like I used to anyway.Posted 3 years agoavdave2Member

I think you’ll find the long term answer is no as well. I’ve had a Rohloff for 9 years and in that time its’s had an annual oil change and is currently on it’s 3rd sprocket and chain and second chainring. It’s ridden all year round in all weathers and never properly cleaned. High initial cost but pence per mile it’s been a good investment. I hardly think Sram and Shimano want to sell you something that doesn’t really wear out. It’s a real shame as I’m sure if they did put their resources behind it we might see the end of the derailleur on off road bikes.Posted 3 years ago
I know there is the Alfine but it seems from everything I’ve read that when they expanded from 8 to 11 speed they lost a lot of the reliability.
There are loads of bikes that use the Pinion, just mainly all small brand stuff… see here
A friend of mine has one and I was surprised how cheap they are, seems most brands are sticking significant ££ onto their prices just because its new tech.Posted 3 years agoalexxxMember
I’ve got the G2 and it’s an awesome riding bike if not a little short and a little heavy (the latter doesn’t matter once riding though).. Ive also got a capra thats the other end of the scale, light and long! they both ride awesome and are super fun bikes.. the G2 is less playful but it will eat anything with confidence and stability and hard to shake off a line!
I’m still genuinely shocked not enough people got behind the G downhill bikes as we’d have seen a carbon one come out before now if they did and probably with the pinion box which would be an awesome awesome experience.
It looks like Rob’s made a super competitive bike with this trail bike and I hope he starts selling them in their thousands as the man deserves all the credit he can get.
It is a shame the high pivot has gone as that was one of the defining features of the zerode.. taking a wild stab I’d say it was probably 1 step too far for consumers to get their head around as everyone wants to see a suspension design they instantly recognise now a days and in that sense I bet he sells a lot more of these than the dh bike!
Can’t wait to see them on the market as the capra frame will be getting flogged instantly!Posted 3 years agotheGrinderSubscriber
I must be missing something with this pinion gearbox. I cannot work out how the actual gearbox has any effect on the output from pedalling.Posted 3 years ago
I understand how the gearbox internals work but unable to understand how turning the pedals is affected by the gearbox.
Normally the pedals are turned and the output from the pedalling becomes the input to the gearbox then the output from the gearbox drives the chain/belt – this does not.
Can someone explain please? – it must work but i cannot see it.
To me it looks like the bike is effectively a “single-speed”theGrinderSubscriber
ah ha – well thanks for responding. The penny has dropped now with that simple explanation. I don’t think i would have got that – i could not see it in photos or strip-downs!!Posted 3 years ago
So your pedals are spinning at whatever revs you’re pedalling at but the chainring is spinning at the geared output – either faster or slower or even the same speed.
I have nothing to add other than I think that looks like a lovely bike! I have never ridden a gearbox but like the idea of progress for less maintenance, if it improves the suspension performance then great, less time fiddling with the bike and more time riding is what interests me.
