标 题: lezyne steel floor drive打气筒使用报告
发信站: BBS 未名空间站 (Fri Nov 4 21:57:08 2011, 美东)
原以为下下周才到的气筒，居然今天就到了，超级大的一个大箱子，
一堆气泡里面一把小气筒。
anyway,包装很简单，但是拿出来就感觉很不同，非常有质感，而且
非常轻，我原来还以为铁的多重呢，感觉比walmart那个还轻些。
做工不用说了，德国人的东西，真叫一个精致。看看金属脚踏板上的
字母就晓得了，金属头上面的presta/Schraeder字样也是刻在上面的，
非常精致。
直接把俺的驴拉过来打气，打前轮，还是打不进，边打边漏，惊了！！
重新拧一次，再打，同样结果。 再拧下来，得，内胎的金属头整个被
拧下来了。 我估计这个内胎的头就是个坏的（当时店里白送的个）。
看来nothing is free啊。。。我又给后胎打气，一切正常，
打了几下就打到110psi了，很轻松。 确认了是前胎的问题。
于是乎，也体验了一次换胎，... 阅读全帖 |

Cervelo 为了研发 R5ca, 还特别做了一台特制的 soloist team, 里头装

Beginner technique: Hill climbing made easy
53 comments By Phil Mosley, Triathlon Plus | Friday, Jul 24, 2009 2.00pm
It’s something we’ve all asked ourselves at the foot of yet another
seemingly endless climb – should we sit or should we stand-up? And yet
surprisingly few people know the answer.
You’ll have noticed that some riders prefer to keep their bottoms
diligently on their saddles, churnin... 阅读全帖 |

leave my roadie outside at all, not even in shared bike locker. I won't ride
unless I know it is ok for me to leave it in office.
Bikeradar or some other website did a test previously. They show that even
with the strongest D lock, the bike can be taken under 5 minutes if they've
got the right tools.
I know you can always claim some money back from the lock company (if you
get the proper one), or your insurance. But hell ... 阅读全帖 |

Achieving your optimal cycling weight will make you faster, and fitter. But
what is it and how do you reach it?
“Excess body weight is the cyclist’s enemy,” says Matt Fitzgerald, author
of Racing Weight: How to get lean for peak performance (VeloPress). “It
wastes energy, slows you down, affects performance and stresses joints.”
You can’t change your basic physiology such as height, limb length and even
potential for leanness, but, ... 阅读全帖 |

Boulder, Colorado-based company Stages Cycling is launching a new direct-
measurement power meter at Interbike that weighs just 20g and costs as
little as $699.
The StageONE power meter is built into slightly modified left-hand crankarms
and directly measures power via a strain gage array, custom electronics,
and a special algorithm that filters out non-applicable forces and
interpolates total left-plus-right output. Claimed accura... 阅读全帖 |

发帖数: 1654 | 26 如果需要长时间放在外面的话，建议买便宜的single speed。以前看过一个视频，好像
是bikeradar做测试，无论什么锁，只要工具得当，5分钟也能搞定了。不过即使这样，
D-lock也比一般的锁强。有的比较大的锁公司，如果你的车用他们的锁被偷了，他们
cover你一定的车钱。你可以查查这些锁公司的网站。
你说的flash lights是指bike light么？如果是的话，bike lights和头盔一样都是骑
车必备的。Cateye和Blackburn都不错，当然Lezyne的更好，不过比较贵。一般交通法
规规定，使用的时候前车灯不能闪，白色；后车灯可以闪，红色。 |

话说壮壮当年的团队最后为了磕药的事情也是撕破脸，互相指控....
哦，看错，狗了一下：
http://www.bikeradar.com/road/gear/article/what-is-a-sportive-1
Most, if not all, sportives use timing chips ensuring a healthy level of
competitiveness is always present no matter what. Results are usually
published in detail on the event website and often have gold, silver or
bronze time standards, and nobody wants to see their name languishing at the
tail end of the table.
貌似应该也有timing chips啊... |

发帖数: 5141 | 42 在这点上，我和铁哥意见完全一致。我个人的原则是，如果用了最小档，还是蹬不动，
那我就要站起来了。否则就一直座着爬坡。
爬坡的话，掌握好换档和踏频，通常座着骑更有效率。我们这个小岛，据说没有真正需
要站起来骑的坡。貌似只有环法那样的路段才需要站着骑。当然美国大陆地大物博，可

Carmichael indicated that the Texan would compete at the 2011 Ironman World

Carmichael, speaking in Hawaii before the 2010 World Championships begin on
