Chris Canfield’s new Vampire Bikes challenge kicks off with one extremely adjustable, high-pivot Fastarossa DH body design and three suspension patents tucked inside. CF3 is the important thing. 3 adjustable pivots. 3 journey settings. 3 potential rear wheel paths. Chris calls it a “quiver killer”!
Strap in. This one will take a minute to wrap your mind round.
Vampire Fastarossa DH bike debuts adjustable CF3 suspension
Ex-DH racer Chris Canfield has been designing mountain bike suspension for 2 and a half many years, most just lately beneath the corporate identify Suspension Formulation. We greatest know his present suspension designs from these developed together with his brother Lance Canfield for his eponymous bike model, and in addition for full-suspension Revel Bikes, each of which license his CBF – Canfield Stability Formulation
However he has loads extra loopy suspension concepts, so determined it was time to show all of it into one final DH bike.
Chris additionally sat down with us a few yr and a half in the past for the Bikerumor Podcast Ep. 086 to elucidate multi-link mountain bike suspension designs in a means that extra of us may perceive.
OK, so what’s new right here, and what carries over.
Canfield Stability Formulation patent tech
First, let’s begin with CBF, that is Chris’s patent that’s already on the market on lots of bikes. Mainly, it’s a digital pivot design the place the Instantaneous Heart (that’s basically the momentary digital pivot at any level all through a motorbike’s journey) is at all times in step with the highest of your chain, because it comes off your chainring delivering energy to the rear wheel. Because the rear wheel goes up, the IC goes down to remain aligned with the taut part of your chain beneath load.
Canfield explains that this ends in “most pedaling effectivity” but in addition means the bike can have no brake-jack and no brake-squat, so balanced braking, too.
What’s new is CF3 – Chris’ Formulation Three
The core of what makes this bike so distinctive is its three principal pivot areas. Chris Canfield stated he wished one DH bike that might do all of it “a race bike that might deal with any monitor, from rock gardens to bike park air DH programs. It needed to be versatile sufficient to adapt to all of them.“
So, as an alternative of selecting a low, mid, or high-pivot design, Canfield simply provides you all three in a single body.
Swapping apparently takes just some minutes – simply unbolt the principle pivot axle, pull it out and place it again the place you need to strive subsequent.
Every transfer considerably modifications each suspension journey and rear axle path. Suppose 165mm in low, 180mm in mid, and 220mm in excessive. It even retains a comparatively constant shock remedy so that you get an analogous really feel all through, simply with increased leverage as you elevate the principle pivot and lengthen journey. Canfield explains that you would be able to often set your preferrred spring setup within the center place after which add high-speed compression damping going up a gap or decrease HSC taking place (plus 1 click on of rebound for every gap going up.)
That means you may get three bikes in a single – from enduro bike really feel to professional DH shredder – all fast and straightforward to swap forwards and backwards relying on the way you need to journey.
I-Monitor Suspension license
The ultimate patent that makes the brand new Vampire Fastarossa DH bike tick is the i-track dynamic loafer pulley design that Canfield licenses from Australian suspension designer Hugh McLay. Mounting the i-track loafer pulley on the Fastarossa’s swingarm signifies that as you pedal tougher, a bit extra pressure (anti-squat) is added to the suspension so it stays extra steady whenever you put the ability down. And the drive is stronger early within the journey, having much less affect whenever you push the bike deeper into its journey.
Vampire Fastarossa DH – Tech particulars

And sure, there are bats infesting Vampire’s web site that always flutter round (and presumably will drive you loopy whenever you attempt to learn concerning the bike’s specs!)

- 7005 aluminum seatstays, chainstays, and linkages for gentle weight & stiffness
- variable 150-220mm rear wheel journey relying on principal pivot place & Trunnion shock stroke size from 67.5-755mm
(for ex. 165/190/220mm with a 75mm stroke) - 3 principal pivot positions – fast swap Low, Mid & Excessive pivot setups in a single body
- chainstay mounted i-track loafer pulley might be swapped with a chainguide within the Low place
(and saved on the additional non-driveside mount) - 29″ or 27.5″ rear wheel with decrease shock mount flip-chip
- exterior cable routing, however with stealth routing for a dropper submit
- IS44/56 tapered headset
- 34.9mm seatpost, features a Cane Creek 31.6mm shim
- 180 submit mount rear brake
- 1 bottle cage + 1 device service cage mount on every body
- 73mm BSA threaded backside bracket with ISCG05 tabs (52mm chainline)
- Enhance 148mm spacing
