Taniwha

The Taniwha carbon frame is custom built around the incredible Pinion C.Line gearbox that enables us to create a quiet, efficient, low maintenance trail destroying weapon.

By removing a considerable amount of unsprung weight from the rear of the bike the suspension is free to work like on no other bike you've ever ridden - allowing for a much more compliant and confidence inspiring ride.
The Taniwha is a no compromise modern mountain bike - ride one and realise what you've been missing out on.

Why choose a Taniwha?

The revolutionary use and placement of a gearbox at the heart of the Taniwha frame allows us to revisit the key concepts of suspension design, such as optimised wheel path, sprung to un-sprung ratios and mass centralisation. Concepts long ago discarded by the bike industry because of the limitations of the drive train we all know and hate.
Whether you are privateer pushing hard to compete at the World Series or a weekend warrior after the best suspension available the Zerode Taniwha is for you.

Fundamentally the Zerode Taniwha is about making the mountain biking experience better.

Nothing inspires us to ride more than a quiet, low maintenance, confidence inspiring bike.

The Pinion C.Line gearbox offers a huge spread of gears that goes well beyond today's 1x12. Whether you are grinding up an epic backcountry single track or blasting down a high speed fire-road there is a gear to do the job. And every gear is accessed with optimal chain line, and no 'outside interference' from things like mud, twigs, leaves and all the other usual trail debris that gets ground into your gears during the course of a ride. An unexpected pinch climb will never be a problem again, changing gear is effortless and immediate. 

A significant reduction in unsprung weight ensures suspension performance that is undeniably better than any mountain bike equipped with a rear derailleur. Symmetrical spoke angle ensures a very strong, light rear wheel that further improves suspension performance. 

A simple, effective and proven suspension platform combined with a fixed chain line optimizes pedaling performance through the entire travel range. It is difficult to approach the elegance and performance of this layout with any virtual pivot design. A sleek full carbon frame offers excellent stiffness, reduced weight and flawless beauty with modern geometry. 

Maintenance and tuning of gears are almost nonexistent, sprocket and chain life are massively extended. On a Zerode, that brand new drivetrain feeling happens every day. 

For those that ride for fun, the Zerode Taniwha will inspire you to ride in any conditions on any trail. If you are racing, whether it for an EWS podium or for bragging-rights amongst mates, the Taniwha provides an edge over your competition. 

Warranty

The Zerode Taniwha frames are warranted against manufacturing defects in materials and/or workmanship for three years from the date of original purchase.

This limited warranty applies only to the original owner of a Zerode Taniwha and is not transferable to subsequent owners.

This limited warranty is void if the bicycle is subjected to abuse, neglect, improper repair, improper maintenance, alteration, modification, an accident or other abnormal, excessive, or improper use.

Taniwha tech FAQ's

Is grip shift the only option? 
It turns out that the grip shift is a very nice match to a drive train when you do not have to pedal to change gear and the gears change instantly. If you get caught out in the wrong gear on a pinch climb you can back off for a split second and rip through a bunch of gears with a twist while the derailleur guys are trying to pedal over the top of the wrong gear or click and crunch through gears one at a time. There is no comparison in this situation. You can grab gears when coasting or back pedalling so you adapt and change when and where you shift, the grip shift lets you do this in a seamless way. We have no doubt a trigger will be available at some point (Rob has designed one on paper, friends have made their own) but we're not convinced experienced Pinion users will want to swap the grip for a trigger.

Why no Horst link?
In a nut shell, we don't like them. The pedalling performance of a Taniwha is second to none. The "real" pivot design combined with a fixed chain line means it is possible to achieve very stable pedalling through the entire range of suspension travel while independently controlling the suspension rate via a link. With a Horst link or VVP design the virtual pivot races all over the show making it hard to control suspension rate and pedalling independently. You get a compromised design despite what the bike industry's marketing departments tell you.

Brake jack? 
There is a huge amount of misinformation online about brake effect. The story goes, "single pivot designs suffer from brake jack or brake lock out". In reality all bikes, even bikes equipped with Horst links have brake effect to some degree. What happens is the traction force at the rear tire tends to rotate the suspension about the pivot, whether real or virtual, causing a suspension compression. It's worth noting the traction force at the rear wheel is usually small and so is the compressive effect and that the suspension is still free to respond to other inputs. Some bikes have more compression than others, in some situations this compression helps performance, in other situations it hinders performance. 

We could go into an in-depth analysis of brake effect. However, there is no need, motorcycles have used simple swingarm designs for over a century now, motorcycle designers fully understand brake effect and understand that a simple swingarm design is the best solution. Almost every DH world champ since records began had a bike with a brake effect essentially the same as that of a single pivot bike. 

Gearbox range?
Imagine a 10-60 cassette. Enough said.

Gearbox drag?
Obviously there is an extra element in the drive train so there has to be losses. The loss is small and depends on load and gear. A comparison with a clean mech with a chain in the middle of the cassette would obviously have a standard mech come out on top. If you take into account a significant reduction in unsprung weight, changing gears instantaneously and the fact the standard rear mech drive trains efficiency falls off quickly when the chain is at the top or bottom on the cassette or when sprockets are small, then add a little bit of dirt or mud the Pinion becomes very attractive. We wouldn't use one on a road bike but on a 160mm trail/enduro bike for riding proper mountain bike trails it is a no brainer.

Why a gearbox/what about the weight?
If you add the new Pinion C.Line gearbox, and take away a cassette (unsprung weight), derailleur (unspring weight), chain guide and build a lighter stronger rear wheel the weight 'disadvantage' of the gearbox is ~500g (the weight of a bottle of water). Given that you have to power yourself and the bike up hills and overcome rolling and air resistance the extra effort required when climbing is almost not measureable. Even if it was we would happily take that compromise if the reward was a significant improvement in suspension performance, 600% gear range, stronger rear wheel, almost no maintenance, chains that last years, shifting without pedalling, instantaneous shifting, no chain slap, optimised pedalling etc etc. We'd be very surprised if Taniwha owners ever go back to a bike with a derailleur.
