Chad Butts just got Rotor’s new Power Meter Cranks so I stopped by his
studio while Mark Purdy installed it. Here’s a quick first look at this new
power meter.
The Rotor retails for $2350, which puts it between the other two major crank
based power meters, SRM and Quarq. Its major feature is that it’s
essentially two power meters, with 4 strain gauges on each crank ... 阅读全帖 |

发帖数: 390 | 7 Hi, I have a 99 dodge neon with SOHC engine. Recently, my car sounds weak
when cranking. My battery is about 4.5 years old. It is a 610 CCA battery.
and I had the battery tested and shown 534 CCA left. The battery voltage
was 12.54V. Time for cranking is 1.2 s. The meter indicated that the
battery need to be replaced soon though I think 534 CCA is considerable
amount left. Some new battery is only 550 CCA. so I think 534 CCA should be
fine with my car. not sure the meter made the decision ... 阅读全帖 |

发帖数: 108 | 8 This afternoon my car didn't start at all.
After a while, I openned up the hood and randomly touched a few things, then
the starter could crank now. It cranked very slowly for the first 5 seconds
, then normally and I can get the car started!
But why the started seems cranking very slowly for the firs few seconds?
Does that mean the battery is going to die or what?
Thanks. |

Left hand side crank arm has left hand side thread
You only need an open wrench to put pedals on or take it off, 15mm if I am
right. You need metric allen-wrenches to work on the crank arm.
This does not look very good. Part of the thread is beat up. Double check it
and see how much of the thread is good. If the good thread is more than 50%
of original thread depth, re-tap the beat up thread to make it smooth. The

might end up a saddle creak or, in rare cases, cracked frame. start by
tightening everything up. BB cups, saddle clamp, seatpost clamp, pedals,
crank arms.
not knowing what cranks you have i can't tell you what tools you will need
for the crank and BB. |

发帖数: 1 | 11 最近发现Japan Domestic Market的BC轮子，有一个特殊的种类，就是在saltwater轮子
里，有一些BC轮子使用的是加长的cranking handle，加大的knob，也号称是extra
cranking power. 但搭配的却是很浅的finesse线杯。譬如Shimano的ENGETSU BB，其他
的品牌也有类似产品。
Shimano网站自己的简介里说，这个轮子是专门为钓snapper设计的。没钓过海鱼，所以
不太懂，但如果用那么浅的spool，那就意味着得用很轻的线了，要不然cast的时候一
下就到头了。如果用那么轻的线，或者抛投的也不是很远，那power cranking还有什么
意义呢？我觉得那就只能用日本市场卖的那些超细但超强的PE线了，但在BC轮子上用这
么细的PE线，很容易出现dig-in的问题啊。这里海钓的朋友们答答疑？ |

发帖数: 1 | 17 嗯，我在网上只看到包装盒上写着是PE #1（也就是10磅braid）200米，不过看起来真
是挺浅的。hanyu621的解释也有道理，那样的话是不需要太多的线。
可以考虑搞一个玩玩，USDM的cranking reel的spool都是巨深无比，但很多时候用
light crankbait，squarebill的时候，我根本用不着那么多线。这个"finesse”的
cranking reel看来挺合适的，相对较浅的线杯也更适合远抛轻饵。
谢谢啦！ |

发帖数: 10 | 21 本人新手，第一辆车，问几个小问题啊。。。
01年gs300,140k。在mechanic那inspect，说rear crank seal漏油（engine和
transmission之间）。开的时间长了，engine oil level low的灯会偶尔亮，尤其是停
在一个上坡或下坡较长时间，但开动了灯又不亮了。没有其他症状，地上也没有漏油的
痕迹。修这个东西大概要多少刀啊，能自己弄吗？
另外刚把四个胎给换了，之前的四个胎中，两个后胎磨得不均匀，mechanic说不用
alignment，是因为有一个轮子是主驱动轮，所以会磨损不匀。是这样的吗？怎么判断
是否要alignment啊？

发帖数: 428 | 31 crank arms don't usually make noises.
if there are noises when you pedal, it's probably one of two things, pedals
or bottom bracket. |

发帖数: 159 | 32 when does the noise happen?
At the middle of every stroke when you have the most torque?
Sounds like a BB bearing seal or bearing problem.
Normally, You just need an allen wrench to pull out the crank arm then you
can see the bearing seal. |

发帖数: 1930 | 40 我对海钓也不算懂，跟船长钓过几次snapper，一知半解，来班门弄斧一下说说自己的
猜测。
我感觉如果是专门钓snapper的话，那这么设计还是有一定道理的。
首先就是海钓snapper之类的肉鱼基本不溜，都是一通暴力拉。如果手稍微慢了，立马
就被鲨鱼打劫了。所以需要这种暴力extra cranking power.
至于浅杯，一般性钓snapper主要是浅海珊瑚礁，所以用不了太多线。浅杯的话相对应
的轮速比高一点（中间的线杯转一圈绕进来的线更多），也就是之前说的，能尽快的把
鱼摇上来，降低被打劫的风险。
当然这纯碎是我的猜测哈。 |

发帖数: 1 | 41 算了吧，才发现这个reel没有用到X-ship,就是那个额外的bearing支撑pinion gear。
买Shimano的cranking reel但没有X-ship, 就好像买espresso但要decaf一样，没啥意
义了。 |

"Usually the Crank–Nicolson scheme is the most accurate scheme for small
time steps. The explicit scheme is the least accurate and can be unstable,
but is also the easiest to implement and the least numerically intensive.
The implicit scheme works the best for large time steps." |
