下坡 Descending

下坡 Descending <p>要下坡下的有自信需要有適當的姿勢來煞車、轉動和吸震，把你的身體當作一個避震系統，以攻擊姿適開始，把腰、膝蓋和手肘彎曲，把腿和手臂當作吸震器。當坡度變陡把你的重心往後放，往後移動把重心放在你的雙腳，保持你的重心在兩輪中間，這個站姿讓你有信心而且穩，你不會被彈來彈去，這個姿勢可抵銷煞車的力量，也讓前輪較輕的去過障礙物。這聽起來跟你的直覺相反，可是有個很重要的一點是下坡時記得要放鬆，試著流暢的動作，如果你放鬆騎而且彎曲你的膝蓋和手臂，輪胎會保持接觸地面讓你更好控制煞車的抓力。<br/>Descending with confidence demands a proper body position for braking; turning and shock absorption, position your body to act as a suspension system.Starting in the attack position bend out the waist knees and elbows so legs and arms can act as shock absorbers. Get your weight back as the grade get steeper, moving back focusing the weight on your feet, keeps your weight centered between the tires, this stance would give you confidence and stability, you won’t get bounced around, and you would be positioned to counteract braking forces, and un-weight the front wheels so it can it can lower over obstacles. It sounds counter intuitive, but an important thing to remember on descends is to relax, try to be fluent with your movements, if you are relaxed, with your knees and arms bend, you help the tires stay in contact with the ground for more control of braking traction.</p><p>22:41<br/>保持握緊手把但是不要讓手臂上的肌肉緊繃，如果你的腿和手臂僵硬更多震動會傳到你身上，你的思考和視線彈跳時都會不清楚。在不平的路面上你不要把臀部放在坐墊上因為你會被往上往前彈，如果你被彈來彈去的就不夠穩騎不快，站在踏板上讓你的車子在你下面游移，你會覺得當你用大腿夾住坐墊時跟腿稍彎時騎起來非常不一樣。打開雙膝騎可讓坐墊游移更多，讓坐墊在你大腿間動，路越差你越要讓車子游動。訓練你的視線去選擇最好的路徑，專注於你想要騎的路而不是你害怕走錯的地方，掃視前方的路徑，由遠往近看，你騎的越快就必須看的越遠越常看。<br/>Keep a firm grip with your hands, but make sure muscle tension does not extend up your arms. If your legs and arms are rigid you transmit more shock to the rest of your body. You can’t think or see clearly if you are being rattled around. In the rough sections you can’t have your butt in the saddle because you get bounced up and forward, if you are getting bounced around, you won’t feel stable enough to ride faster. Stand up on the pedals, allowing your bike flowing around beneath you. Your bike will handle very differently, when you clamp your seat between your thighs as compared when you ride slowly slightly bow legged. Riding in open stance with your knees out allows the saddle to flow around more, you can wrestle the seat against your thighs, the rougher the terrain the more you would want the bike flow, train your vision patterns to pick the best lines, focus on where you want the bike to go, not where you afraid you will end up. Scan the trail ahead of you, looking up the trial and back, the faster you go the farther out front and more often you need to scan.</p><p>23:50<br/>找平滑的路面煞車有較好預期的摩擦力，能夠降低速度然後放開煞車讓車子滾過障礙物，對這個難應付的下坡你怎麼煞前煞在於你有多少的控制，就我來說當我下巖石時我不會煞太多，但是找個過去後能煞好車的點。這裡有土會讓煞前煞時打滑不過這個石頭可提供煞車抓力，所以當我過岩石時我會放掉煞車，然後上這個石頭有比較好的抓地力後再剎車，然後當抓地力減弱時再放掉煞車，我下這個轉角一定放掉煞車而且我要轉彎，所以我前輪可以流暢的滾過且能抓地。煞車會把震盪傳過你的身體，所以當你在下長坡時可以放鬆你控制煞車的手指這可恢復你手臂的肌肉，輕壓煞車把這些肌肉緊繃，你可以聽到你的煞車桿彈起然後完全放開。要減少傳到你身體的震盪就要加強控制，你不想任一個輪子被煞死然後停住，煞死的輪子會在地面拖行，撞上岩石而不是滾過去，這個很明確示範出失去控制或著就爆胎，輕輕騎把你的重心放兩輪中間不要用輪胎去撞路上的障礙。<br/>Look to brake on smooth sections, where there is better or at least predictable traction it is more effective to slow down to the appropriate speed and then release the brakes to let the bike roll over an obstacle.Here is a kind of a tricky downhill what you do with your front break is that have a lot to do with how much control you have what I like to do when I come over there is not beyond the brakes when I am dropping over the ledges, but looking for a place where I can get good braking traction after I come off of it. Here is some dirt that is pretty slippery to get on the front brake hard in these places but for instance here is a rock that is going to provide good traction. So I might be of the brake when I come over the ledge and on the brake on this rock when I get some good traction and then and then off when the traction is a kind of loose, and definitely off the brake when I come down at this corner and I going to make a direction change, so my front wheel can roll fluently with traction. Braking transmit shocks through your body, so you have the opportunity especially on long descends, relax your braking fingers, this allows your arm muscles to recover, even slight pressure on the brake levers, keep those muscles tense you can hear your levers click out and release them fully. To minimize shocks through your body is to maximize control, you don’t want either wheel to lock up and stop turning a locked up wheel drags across the ground, slamming into rocks instead of rolling over them, this is a perfect scenario to lose control or to get a flat. Ride light with you weight centered between the tires, rather than crushing the tires on terrain obstacles. </p><p>我經常騎車的夥伴和職業賽車手Daryl Price在過石塊時相當出色，你要如何描述過一連串都是尖石的路段？好，最簡單的做法是把你的重心放於輪子跟地面接觸的兩點之間，這是說幾乎在bottom bracket之上或往前一點，前避震需要1或2到3吋更多的行程，而且你後輪很可能會因為那些尖石戳破。<br/>My frequent riding partner and fellow pro-racer Daryl Price, shines when it comes to floating over rocks he said. How do you describe getting through a section where there serious sharp rocks in a row?<br/>Ok, the easiest way to do that is to center your weight over the two contact patches of the wheels, and that means almost directly or a little bit forward of the bottom bracket and with front suspension needs a couple to almost 3 inches more front travel, and mostly the sharp rocks going to give you a rear flat.</p>[em07]
