The Art of Descending on a Cruzbike

Riding regularly in Appalachia for the past twenty years has given me considerable experience with steep, technical mountain descents. When riding with groups of road bikes and other V20c recumbents, I will be faster than many but slower than the more skilled and/or intrepid descenders. I’m a cautious descender, more concerned about what might be coming the other way around the corner.

Significant Advantages of the Cruzbike V20c over Traditional Road Bikes when Descending and Cornering: 

The Cruzbike V20c has a number of significant advantages over a road bike when it comes to high-speed descending and cornering. Let’s review those advantages, and also the caveats, of descending on a V20c (and these also apply to all other Cruzbike models).

• Faster/easier leaning: The lower center of gravity (CoG) on the V20c directly translates to faster leaning by reducing the roll moment of inertia. This means you can initiate leans faster and more easily than someone on a standard road bike because it takes less steering torque to get the bike leaned over quickly. Every once in a while, someone sends me a video of a standard road bike racing down a curvy hill, with the rider leaning way off to the side, and they say “see, you can’t do that on a Cruzbike!” Thanks to our lower CoG, we don't have to throw our body to that extreme to get the same lean angle.
• Greater stability once leaned: The Cruzbike resists tipping from bumps, wind, or road imperfections far better (higher rollover threshold) due to the low CoG.
• Ground-clearance advantage: On an upright bike, inside pedal strike can be devastating, and usually limits lean to ~35–45°. On the Cruzbike V20c, the pedals are positioned much higher, so you can safely lean 55°+ before anything scrapes. This means the bike can handle higher speeds or tighter radii before it runs out of lean angle. Result: Riders can corner at higher speeds than on a standard bike while staying well within the bike’s safe lean limit. Because you’re already positioned closer to the ground, the perceived lean often feels less dramatic even though the mathematical angle is the same.
• Longer wheelbase = directional stability: The Cruzbike V20c has a notably long wheelbase of ~1149 mm (45.3 inches)—longer than most road bikes (typically 980–1050 mm). This gives higher directional stability—the bike tracks straighter and holds its line through the corner with far less correction. It resists weaving or “standing up” mid-turn. Once leaned in, the longer distance between the tire contact patches makes small steering inputs less twitchy and gives a rock-solid feel. Trade-off of the longer wheelbase: Slower turn-in and larger minimum turning radius at slow speeds—you need slightly more steering input (or more countersteering) to initiate the lean, and the bike prefers sweeping corners over tight, flickable ones.
• Unfettered gravitational speed: The aerodynamics that make the V20c fast on the flats truly shine on the downhills. Be prepared to hit top speeds far above what you are used to, and to reach those speeds very quickly. This can be exhilarating… or terrifying, depending on your perspective. I remember beginning the infamous “glass elevator” descent to Borrego Springs, California during the 2017 Race Across America, and glancing down at my Garmin to see a speed of 57 mph after what felt like only a few seconds of coasting. I couldn’t enjoy the speed for long because there was a giant boulder straight ahead, preceded by a sharp turn of the road toward the left… and that brings up the next topic.
• Superior emergency braking: Descending at speed on a twisty road frequently requires using your brakes to stay out of trouble. Let’s say you are rounding a corner and suddenly a Ford F-250 pulling a bass boat is coming up the hill while trying to pass an RV (I’ve seen stuff like this all too often). The lower CoG and longer wheelbase of the V20c allows a shorter/quicker stop with less risk of a face-plant-endover compared to a standard road bike.

Descending caveats:

Barreling down a hill at 65 mph is not the best time to remember that you forgot to tighten the thru-axle after that tire change. You should check your bolts and brakes before every ride, but especially before rides where high speeds are expected.

 Make sure your derailleur limit screws are set to prevent the chain from dropping off the cassette or chainring. I also recommend NOT trying to shift gears when you are traveling over 30 mph. When I begin a downhill, I shift all the way into the lowest gear (biggest chain ring and smallest cassette cog) while my speed is relatively slow. I don’t want to risk a chain derailment at high speeds.

An important message about initiating pedaling at high speed:

You will likely start coasting (stop pedaling) when your downhill speed passes about 30-35 mph. At some point during that downhill segment, as the slope gets flatter, you will want to start pedaling again while you are still moving pretty fast. That’s fine, but… don’t stab the pedals! A sudden punch to a pedal can induce a front-end wobble, which may lead to a crash or at minimum a serious “pucker” moment.

Begin the pedaling motion gingerly (without much force) until you feel the resistance as the ratchet and pawls engage in the front hub. Once you feel that engagement, then you can ramp the force up to full power. My V20c has a 44T chainring and 10-52T cassette. With the chain on the 10T cog, my "engagement speed" is 29 mph at a cadence of 85 rpm. Therefore, I will wait until my speed drops to 29 mph before I resume pedaling. If all these numbers are too complicated for you, don't worry about them. You will learn from experience what engagement speed works best for you.

In-flight checklist

When I am cruising on a big downhill, here are seven things that I am thinking about:

1. What's coming up ahead?

   At high speeds, it's important to be visually scanning ahead for any road debris, potholes, cars, dogs, deer, other bikes, etc. Of course, we cyclists are always doing this, but it becomes more vital at higher speeds. At 40 mph we are moving 58.7 feet (17.9 meters) every second. Fortunately, the face-forward position on the Cruzbike V20c gives a good viewing angle for identifying upcoming threats; much better than the head-down tuck position on a road bike.
   
   
2. What might be coming up behind me?
   
   I take an occasional glance at the rear view mirror to see if there is a motor vehicle or other bike approaching from the rear. If there is, I will hold my line, or, if safe, move gently toward the right. Sometimes it is safer to stay in the middle of the lane and just make cars wait a little. You need to make that judgment for yourself.
   
   
3. Optimal grip on the bars and brake levers.
   
   My hands may be on the hoods, ready to feather the brake levers; or down on the drops. I tend to prefer the dropped hand position when I am going very fast. The drops give me a firmer grip on the handlebars and the ability to put more force on the brake levers should I need it. My grip tends to be firmer at high speeds, while avoiding an overly zealous "death grip".
   
   
4. Optimal leg position.
   
   My legs may be in the 6 and 12 o'clock position (one up, one down) or in the 3 and 9 o'clock (one forward, one rearward). You should experiment with both positions and see which feels better to you. The 3 and 9 o'clock seems to be a little more aerodynamic for me, so I will adopt that position for maximum speed. Remember that your legs are heavy and strong and they are helping your upper body to stabilize the front wheel position.
   
   
5. Any unusual sounds or vibrations?
   
   Use your ears. Despite the loud rushing wind, you might hear something important, like a tire hissing due to a puncture. If you hear or feel anything unusual, it is best to pull over and check it out ASAP. Carefully apply the brakes, unclip your shoes, and be prepared to make a safe stop out of the traffic flow.
   
   
6. Plan safe passage through the next corner.
   
   Curve ahead? Look through the corner to the exit as early as possible. Your vision dictates your line and speed—staring at the ground in front of your wheel makes everything feel rushed and tight. Pick your entry line early while scanning for loose gravel, sand, wet leaves, etc. Do all your speed reduction before you start leaning into the corner. Use mostly the front brake (70–80% of stopping power) with progressive, smooth modulation—avoid sudden braking, as that can cause speed wobbles and/or loss of traction. Enter the corner at a speed where you can release the brakes entirely through the turn and let the bike roll freely, which preserves maximum tire grip. Approach wide (toward the outside of the turn), turn in to clip the apex (the innermost point, usually about 1/3–2/3 through the corner depending on radius), then exit wide to straighten the path as much as possible. This effectively lengthens the radius of your turn, allowing higher speed with less lean angle and less risk of sliding out on a sandy patch.
   
   
7. Braking and heat management.
   
   On a long downhill, it is possible for brake pads to overheat. Rotate the use of front and rear brakes to allow each a chance to cool, keeping in mind that if you need serious braking, the front brake is the most important for stopping power.

Summary:

The Cruzbike V20c’s combination of low CoG + long wheelbase is why owners consistently describe its cornering as “carving like it’s on rails”—fast, stable, and confidence-inspiring even at high speeds.

Compared to standard road bikes, the lower CoG enables faster/easier leaning, and quicker/shorter emergency stopping. The elevated pedal position provides a much larger (and safer) ground-clearance margin. The long wheelbase gives you planted tracking and enhanced stability— very different from a standard bike that can feel more nervous at the limits. But there is a learning curve with the V20c, and you should be careful and gradually acquire your descending experience, starting with smaller hills and working your way up to larger and steeper hills.
