发帖数: 159 | 7 700 is the nominal rolling diameter in mm. Probably because bicycles were
invented in non English countries, it is millimeters instead of inches. I
have no idea what the heck that C mean. But it always comes as 700C-xx.
23 is the width in mm. Normally, regular road bike tires are 23-25 mm wide
and cyclocross tires are 28mm wide. It is possible to put 28mm cyclocross
tires on the 23mm rim. |

发帖数: 3290 | 8 Agree. 700x23 might be more common in races. But the difference it makes
probably only makes sense for those whose podium positions are determined by
only a couple of bike lengths. |

Local 推荐 CAAD10 5, 不过frame 不是碳纤，但是以后的service肯定用得上
Performance 的Altamira 3 LE看起来不错， 全碳纤， 可是纽约附近没有Performance
的店。。
大家给点建议啊。 谢谢。

发帖数: 239 | 17 实测结果，在有一定坡度的路面，路车不占便宜。
路车：Tire: 700x23, 100psi. Weight 23LB。Gear ratio：34-50/12-25
山地车： Tire: 26x2.1, 40psi. Weight 26LB。Gear ratio：22-42/11-30
往返里程共16麦。高差700尺。有几处5%的坡。
平均速度：路车14.7mph， 山地15.2mph。
最大速度：路车28mph，山地27.2mph。
两处作弊的地方：
1）山地车爬坡总能蹬得动，挂到最小挡，很陡的坡也行。路车在最陡的地方就可能停
下来。
2）下坡，路车还能加速，如果把身体踡起来，Gear也没用完，但出于安全考虑，不想
再加速了。山地车已经把身体尽量降低，Gear也都用完，没有多少加速的余地了。
难点：找到一样重的路车和山地车不容易。23LB的路车算比较重的，26LB的山地车则是
比较轻的了。
不会贴图，只有报数据了。 |

发帖数: 239 | 18 最近把路车从铝架碳叉车升级到全碳车。还是翠克的高端系列。昨天出去骑了三十麦。
出发前照以前规矩把700x23的轮胎打气到100psi。结果骑了一圈回来，那个难受。上坡
是舒服很多，因为车轻很多。但下坡，平路能把人颠出个七荤八素来。稍微一个小坑或
者小石头都能感觉出来。以前的铝架车在同样的路上没觉得这么颠。
这种路感太硬是为什么？全碳车都这样？还是轮胎不好？(bontrager racelite) 还是
气打得太足？ |

发帖数: 239 | 19 700x23的胎，100psi应该不软了。我以前那个铝架车一直都用这个压力。就昨天的感觉
，再多打些气估计能把我从车上颠下来。
不过如果实在找不出原因的话，下次我用110psi试试。
：车轻的原因？而且100psi是不是软了点？ |

这个胎
TIRES: Vittoria Rubino Pro, 700x23
上面写着最低100psi，最高145psi。
好在入弯之前我的从aerobar上起来了，握的车把最宽的部分，偏离了柏油路面，我没
有刹车，猛拐，而是握紧车把，自然降速。
骑快了，在路上压过鼓包，车颠得都离地了，手也颠离了aerobar，还是很吓人的。 |
