Our frame takes all the advantages of high pivot point bikes without the disadvantage of a very high anti rise. Unlike typical HPP bikes, our VHP system conserves the geometry and offers enough traction under rear braking. Further, it provides massive support under pedaling without the downside of pedal kickback. The so-called Anti Squat is even fine-tuned trough out gears and travel.
Bikes with High Pivot Points naturally offer excellent support under pedaling without the downside of pedal kickback when using an idler pulley to reroute the chain. But we went a bit further and optimized the Anti Squat throughout the gears and travel to achieve what we believe is perfection. Plenty of support when climbing but no Pedal Kickback when descending, that makes you faster!
Anti Rise is usually the weak point of High Pivot Point bikes as too much Anti Rise results in a less active suspension and loss of travel and traction. Thats why we payed lots of our attention to design a bike that does not change the geometry under rear braking and keeps the suspension active but also prevents the riders mass from shifting forward. We call that system VHP (Virtual High Pivot) and it makes you faster.
A Geometry that actually fits you is one of the most important factors to be fast. That´s why we don´t even offer any standard sizes like M/L/XL. But we do offer a set of reach and seattube options which can be combined to fit your personal needs. Reach can be anything between 440 and 540mm in 20 mm steps. Seattube can be 420, 450 or 480 and the headtube can be either 110 or 125 mm.
Allowing a high level of customization is vital for a bike that fits you like a tailored suit. That´s why we don´t offer any standard sizes like medium or large. Instead, we offer a set of Reach and Seat Tube options that can be combined to fit your personal needs. Reach can be anything between 440 and 540mm in 20 mm steps. The seat tube can be 420, 450 or 480 and the headtube can be either 110 or 125 mm.
And last but not least, you can decide if you want to build a pure 29er or a Mullet. The switch will be done by exchanging the shock mount so you can change it anytime later on. That totals in 36 possible sizes if we don´t count the Mullet option, no wounder the Geometry table is full of information.

Seat Tube: 450 mm
Head Tube: 110 mm

It all started with a passion project of our mother company 77designz. We wanted to build an enduro bike that delivers uncompromised performance. No market studies, no bullshit marketing kinematics, only serious engineering straight to the point of making the fastest enduro bike we can imagine.
Our goal was to design an enduro race bike that climbs like an all-mountain bike but descends like a downhill bike. To achieve the highest performance, we knew that we need to go down the “High Pivot Point” road. But there was one thing bothering us with that, and it was the high anti-rise that usually comes along with “High Pivot Point” bikes.
We wanted a bike that conserves the geometry and offers enough traction under braking but also provides massive support under pedaling with no pedal kickback. As soon as we figured how we had to design the kinematics, we were ready to start.
We designed with the rule of simplicity in mind; Straight lines, no unnecessary weight, or shape. We believe that straight tubes do the best job in terms of stiffness too weight ratios, and also they hold strong against impacts.
After one year on the prototypes and many exited people who tried the bike, we decided to improve the design towards a production-ready product and go down the route of becoming a bike brand.
The name we choose, ‘KAVENZ’ originates from the German word Kaventsmann, which means ‘Monster Wave’ or reliable and robust person in our local slang (Masemate). As we are proudly going to weld the frame with bespoke geometry options in Germany, we found that the name suits us well.
Q: I want to mount a 180 fork. How much flatter does this make the seat angle?
A: Approx: 0.35 ° in SAG position.
Q: I ride the Sram Eagle. With the high pivot construction, everything is a little different. Can I ride the normal Eagle chainring?
A: No, they wear out so quickly because of the strange tooth profile. We recommend round chainrings from aB
Q: Which options are you going to offer?
A: We will offer build kits including Shocks, Forks, Dropper Seatpost, Cockpit, and Accessories.
Q: Why not going for a 34.9mm Seatpost?
A: Most seat posts available did not make use of the benefits of the bigger diameter and got heavier. Also, many people would switch the frame and keep some components like the dropper post. However, we are thinking to integrate the Eightpins a bit further down the road, eventually becomes available in 2021.
Q: Will you do longer chainstays for taller riders?
A: We believe in short chainstays and have no personal intention to offer longer Chain Stays. However, if the market demands such we will consider delivering with the next batch. Technically it´s easy to do it was just not important to us.
Q: Will you be shipping internationally?
A: Yes, at the moment we are not aware of any country restrictions.
Q: Can I use normal chains?
A: Yes you can, 34T Chainring requires 120 links and a 32T Chainring requires 118 links in combination with a 10-50 cassette.
Q: You mentioned a min. Rear disc of 185mm. It is quite unusual… 180mm was not possible?
A: Yes, it´s rare, but 180 disc is nearly impossible also the 185 Rotor does not allow for all kinds of Rear Brakes, we recommend 203mm with our own Adapter. 29er wheels generate quite some torque and the bike is designed for high speed.Those are the PM Adapter we recommend if you don’t want to use ours:-203mm: Shimano SM-MA-R2003P/S
-185mm: Sram Avid 185R IS/PM
Q: Why is the seat tube not steeper like on other bikes?
A: The Kavenz VHP16 features a 77.5° seat tube angle and does not require a steeper one as the geometry is conserved by the extreme high Anti-Squat.
Q: Is the pedal kickback always the same no matter which chainring size I use?
A: The pedal kickback and the Anti Squat are completely independent of the chainring size so it does not matter if you run a 26T or 36T the kinematics always remains the same.
Q: Can I use Oval Chainrings?
A: Technically yes but it would be almost impossible to find some that offer the correct timing. As the chain is routed differently you can not use any standard chainrings the only option are Race Face chainrings mounted with a different rotation. However, we figured that they create some kind of drag so we do not recommend to use them.
