公路车架买大了有多惨

开始折腾了，平把不满足了。

一开始觉得平把公路挺好的，满足了通勤偶尔骑行的要求

随着越骑越多，时间久了感觉还是弯把更加和谐的，特别是在双11买了新的碳纤维轮组之后。

觉得平把配碳刀实在是不和谐

接下来就为了改成弯把做准备

首先买了套二手的 SHIMANO 4700 套件（圈刹）

双11买了把带SHIMANO的 PRO 把带

捷安特的超轻铝合金弯把（实体店购买）

开始装车

重量8.07 公斤不包含把带但包含了马维克的锁踏

由于我骑车去的车店，所以没办法一下子骑2部车回去，只能叫了货拉拉

整车配置如下

4700 大套件除了夹器用的是UT 6800。

8.36公斤包含了碳刀+ 脚踏

其实是比较重的重在哪里呢其实就是套件上面 4700的套件的确是重了点因为车架和圈其实重量还好。

我们来算下这次升级的成本

4700的套件是二手的，收来的成本在1311元。

捷安特弯把全新的 200元

SHIMANO 把带 144.51元

手工费300元（现在的手工费是有点贵，手工费包括线管等材料）

所以本次升级一共花费 1955.51+51块的货拉拉

另外静藤的C50碳纤维轮组价格5300.

之所以改这套 SHIMANO 4700的套件其实有2个原因

1. 本来想收 10速的SRAM 手变的一直没有合适的，找到了但是价格我觉得高了 800多有点不值得。

2.整车想搞的和谐点，全套 SHIMANO的套件

3.真的很久没有用过SHIMANO的套件了，上次用SHIMANO公路套件还是UT6500的那是多么久远的事情了。

UT6500还是9速的。。。。。。

4. 原来的铝合金轮组EASTON EA90RT 轮组的塔基只支持10速飞轮，就算升级了碳刀原来的铝合金轮组还是想继续用下去的，因为花鼓还是很润的。出去跑远路的话碳刀会舍不得用。

5. 原车上的SRAM 套件可以挂小黄鱼卖了回血。。。。。

这样看下来，弯把公路车还是比较和谐的。

至于碳纤维车架肯定是趋势，但是我选择钛合金的车架也有我考虑的初衷。

比如下面这图。

车友自己的失误造成的，一个车架就这么没有了。

还好所幸人没事。

拆下的配件都准备挂小黄鱼了。

所以从套件的重量可以看出，我这SRAM 平把套件换 SHIMANO 4700套件属于反向升级了。

下面分析下 SRAM 和 SHIMANO 的重量差别这里说的差别仅仅针对我自己换的这2套变速级别是不对等的，轻不要和其他的套件对比。

牙盘差 234克

SHIMANO 913克

SRAM 679克

中轴差 -17克

SHIMANO 91克

SRAM 108克

飞轮差 96克

SHIMANO 303克

SRAM 207克

后拨差 74克

SHIMANO 257克

SRAM 183克

链条差 -6 克

SHIMANO 242克

SRAM 248 克

刹把指拨手变差 105克

SHIMANO 515克

SRAM 410 克

抛开弯把直把把套把带的重量就以上这些套件差了486克

也就是说如果从重量上我只换SRAM 手变的话

整车的重量应该在8公斤以内

但是从经济的角度来说买SHIMANO 4700套件后换下的SRAM 配件的钱基本上可以COVER

这次升级套件的钱。（FORCE 22 牙盘老值钱了哈哈哈）

当然性能上来说 SHIMANOA 4700的套件总体上要比 SRAM的等级要低1-2个级别。

最终我还是选择了经济，放弃了重量和性能。

因为我觉得从整车配置的和谐性来说， 4700大套件还是更加好看点，和谐点。

在上海的骑行环境中要拉的是平路的速度（基本没有坡）也不差这点重量了想想 8.3公斤的整车和某些 2万左右的碟刹车子差不多的重量还算过得去吧。

邹发狄1244新手,山地车买大了,想换车架,请教? -
邹奖态15073875961 ______ 呵呵你170cm,97kg,强壮型的身材哦! 用16或17寸的车架就行了,我177cm用18寸的刚刚好. 你可以试试换一根短一些的把立,还有把你的坐垫位置前移一些,那么你的身体就不会伸展得那么厉害了, 你的车架实在是太大了很多呀,实在不行的话就换16或17寸的车架吧.

邹发狄1244求助如果公路车架买大了1号应当做哪些调剂? -
邹奖态15073875961 ______ 买大1号,试试放低坐管拉后坐垫(保证屁股的2个顶点到中轴距离不变在同个圆),然后提高巴力.这样也就是偏旅行车的骑骑还行,站起来摇车就不稳定了.建议有条件还是换个适合的车架

邹发狄1244求教车架子大怎么办??? -
邹奖态15073875961 ______ 您身高多少,车架是多少的.如果换短把立还不行,看看车把是不是太低了,要不您得直接换小两寸的车架.

邹发狄1244关于公路车的车架大小高手进.... -
邹奖态15073875961 ______ 车架大小是16 ,17 ,18吧而且那么便宜的车子也没有架子可以换. 你的身高很标准,一般的车没问题.调解好车座和车把高度就行了. 只要你骑上去腿能伸直,手够得着车把,不感觉太远或太进就行了.

邹发狄1244自行车车架尺寸与膝盖疼痛问题 -
邹奖态15073875961 ______ 没必要换车架,花冤枉钱.踏板踩到底腿不能伸直,可以把车座拔高啊.车座的高度以你站立齐胯为准,脚前掌踩踏板到底,腿伸直就可以了.膝盖痛是因为韧带拉伸的缘故,坚持住.慢慢会好的.国庆假期我一天骑行110公里,左腿的膝盖开始疼了,第二天骑行很痛苦不能打弯.我咬牙忍着,不知道什么时候就不疼了.我的好友说是韧带拉开了.祝你骑行愉快!

邹发狄1244想入手自行车公路车请问需要注意什么? -
邹奖态15073875961 ______ 入门公路车至少要1w.几千块的公路车车架设计不合理.尤其是公路车车架几何比列因人而异,如果没有用合适的车架和姿态,会对身体造成危害.建议入车至少入1w的公路车.如果条...

邹发狄1244本人身高180,想买公路车不知该选什么样的架子!大架子是多大? -
邹奖态15073875961 ______ 公路车架子有水平上管和倾斜上管的. 压缩架就是上管倾斜的,像捷安特TCR那样的;大架子就是上管水平的,像捷安特PROPEL那样的,压缩架的跨高比较低,适合身高较矮的人. 你身高180压缩架可以买500mm的,水平架可以买520mm的.

邹发狄1244Giant anyroad2,车买大了,给我个良心建议吧 -
邹奖态15073875961 ______ ANYROAD2的尺寸XS(43.5), S(46), M(47), L(50.5) XS的适合170身高以下人群 S适合170-175身高 M适合175-180身高 L适合180-185身高 XL适合185-190身高这个表格,不同架子的上管、立管数据都标的很清楚,对应其他厂家的车架,不看乱...

邹发狄1244美利达13公爵600车架大了是换车架好还是换把立好,哪个改善更直接和完美 -
邹奖态15073875961 ______ 要考虑两个问题,大多少?做什么用?如果是170用了18的架子,那就大太多了,必须换掉,如果175以上,就可以考虑第二个问题.这里只是举例,你可以说一下身高和车架号,帮你分析一下.稍大一点的车架如果用来越野是不合适的,因为一般越野用的车架都要求小半号到一号,这样操控性更好,安全;但是如果用来远足或者代步的车架,大半号还比较合适,因为车架较大更适合发力,在公路上骑行也不用考虑太多操控性的问题.结论是:1、代步、远足等公路用途,可以通过换把立、换蝴蝶把等方案小改解决2、越野等运动用途,换车架祝骑行愉快!

邹发狄1244公路自行车真的比山地车快吗? -
邹奖态15073875961 ______ 环法虽然处于安全目的,官方一直没有公布过最高时速但转播商出于自己的商业目的会偷巧的拍摄一些时速画面,比如先'无意的'拍一下摩托车或是汽车的时速表然后再拍外边的与之平行的参赛队员,这样就可以大概知道参赛队员的车速了....
