It’s Weirder Than You Assume | Mike’s Bikes
With regards to mountain biking, there are a number of explanation why you must need to nook sooner and extra aggressively:
First off, it’s enjoyable.
Plus, you’ll shave tons of time without work your laps, carry means higher momentum, and, lest we must always overlook, have far more enjoyable. Right here’s the breakdown on how one can nook like a professional in your XC, path, or downhill bike:
Intro: Perceive the Physics
Always, gravity pulls every little thing on earth straight down. On the finish of the day, the distinction between sliding out on a unfastened nook and sticking to it like velcro comes right down to how nicely you’re employed with gravity.
The knobby treads in your tires are designed to chunk into the bottom when weight is straight over them. As in, when it’s coming down at a 90º angle to the bottom. That’s proper: your tires don’t work as nicely when the drive comes down at an angle.
Take into consideration that for a second. After we nook, we naturally lean our our bodies and bikes into the nook. Meaning our physique and bike merely lean over, and our middle of gravity is now over naked floor — NOT over the treads of our tires. This causes them to need to shoot out from beneath us.
If you happen to don’t consider this, seize a sturdy mop. Intention it straight down or at a really slight angle, and you may lean your weight on the deal with. However intention it out at a 20º to 30º angle and lean on it, and it’ll shoot out like a watermelon seed.
Step 1: The Bike-body Method
It looks as if a paradox. If you happen to naturally need to lean into corners, how do you retain your weight over the treads?
The reply: lean the bike, not your physique.
This may really feel completely unnatural and ridiculous at first, however keep it up. Apply on flat floor. Lean the bike left and proper beneath you, conserving your pedals degree and sticking your knee out to accommodate the seatpost and prime tube. One arm will go practically straight as you dip one handlebar grip towards the bottom, and the opposite elbow will bend considerably. The extra aggressively you may handle to lean the bike, the higher your cornering.
Do as a lot contortion as you should preserve your middle of gravity straight over that contact level between the tires and the bottom. Bear in mind, you’re driving your weight straight down onto these treads to assist them get the most effective grip potential.
Step 2: Velocity Administration
Alright, now it’s time for the second counter-intuitive level: your tires will grip nicely till you contact the brakes. If you happen to brake in a nook, your tires will react to the stopping movement by eager to proceed in a straight line. This tends to make them slide straight out of the nook.
To keep away from this, you have to do all — and we imply all — of your braking earlier than the nook. Trip brakeless via the flip, and carry velocity out of the nook. If it’s a brief nook, chances are you’ll want solely a small pump of the brake levers. If it’s a protracted, swooping downhill nook, chances are you’ll have to sluggish your self excess of you’d assume earlier than you enter it. By the point you exit, gravity could have gotten you again up to the mark.
Step 3: Know Your Bike
In the present day’s mountain bikes are unbelievably exact machines. You possibly can implement skilled cornering methods on XC, path, downhill, or every other off-road bike — simply take the time to get comfy with the bike’s geometry.
A working example is the Santa Cruz 5010 C S. This full-suspension XC machine is nimble and notably hungry for cornering as a consequence of its 27.5” wheels, responsive 130-140mm suspension, and an extremely beneficiant lower-link VPP configuration. The slack headtube angle and low backside bracket provide help to do much less contorting to maintain your middle of gravity over that candy spot.
One other instance is the Specialized Stumpjumper Pro LTD 27.5. You’ll rapidly be taught this carbon cornering guru is regular on a rock, even on the rockiest of corners. That is because of its OHLINS RXF 36 fork and TTX22 Coil Shock, in addition to its carbon rims that stay stiff and assured towards all varieties of variables in a nook.
And the Juliana Maverick brings the identical kind of energy in a quick, 29” format. With 140mm of journey and a flip-chip permitting you to regulate the peak of the underside bracket and headtube angle, you may really customise the best way you nook.
