about.
Thomson Elite. Only the 27.2 x 250mm is $62.99 and Silver only. Shipping is
Free. (Other sizes are much more) Arguably one of the finest seatposts made.
You can spend more on the Thomson Masterpiece but I actually prefer the
Elite. It is only slightly heavier but 7% stronger and costs less.
The Thomson Elite normally sells for a street price of about $90. I found
these discounted at Amazon in the popular 27.2 size i... 阅读全帖 |

p*******r 发帖数: 180 | 4 Trek/Bontrager makes clamps for 7x10 mm oval rails but 1) they are hard to
find (I had to call nearly all lbs in town to find a pair) 2) they may not
fit your seatpost. Oval carbon rails can be a pain in the butt, no pun
intended. |

剩下一个螺丝了。其实之前有征兆,骑着坐凳下有时候有杂音。这个是要换整个seapos

j**********n 发帖数: 527 | 8 我弄错了,clamp似乎跟seatpost collar是混着用的。
贴图了。
是固定saddle的一个bolt?从螺纹处断了。 |
|
t****u 发帖数: 10218 | 9 这个难度有点高。断的那部分,像是厂家专用的。这个设计不是很合理。
要是配不到的话,只能整根seatpost换了 |

a****t 发帖数: 720 | 12 昨晚收到,一看,90%的都装好了。原想周末再装的,忍不住10多分钟就把它彻底装完
了。
几点失望:
1.居然是made in china,我以前的4辆车,第一辆made in china的。
2.seatpost居然不是carbon fiber的,again,前面4辆车里面除去2辆老车,其余2辆全
是carbon fiber seatpost, sad~~~
3.超重,competitivecyclist上estimate 17.09lb,我加上eggbeater之后,整车19 lb
,比起我刚买掉的整车18.3 lb都还要重,灰常不爽, sad~~~~~~~~~
4.wheelset,居然不是bladed的spokes。
5.saddle就是一坨shit,前面无凹槽,后面的support不够硬.
略有欣慰,虽然made in china,做工还是蛮精致的。不过$11xx的价格(after
cashback,190刀,已拿到),19lb,full sram rival,应该满足了。
总体来说,就是nothing special,原本还以为会有点小surprise的。 |

l*****s 发帖数: 156 | 13 1991年的Trek 830. Chromoly frame, all stock setup.
买来时pretty beatup, 给wax/buff了一下,换了brakes, cables, 加了seatpost,
grease了一下,轮子true了一下,上路一骑感觉非常不错,很smooth,没想到20多年前
的廉价变速器还是很smooth的,习惯了aluminum车骑chromoly确实能感觉到road bump
absorbtion要比aluminum frame好不少。
Bike: $75
Single Digit 5 Brakes + Brake lever: $56

Seatpost: $8
New cables: $5
换掉的vintage brake lever+v brakes卖掉还能回收$20左右
所以Final cost $124 —— 物美价廉我喜欢 :)

c*******r 发帖数: 13580 | 17 both are important. but tail light is more important. I am fully equipped
with lights: one on the seat stay, one on the seatpost, one on the back of
the helmet, and the super bright one on the front. I turn all of them on
when I ride in the dark. I also have lots of reflective stickers on the
fenders and my backpack. |

y*****y 发帖数: 3433 | 18 我对saddle其实没意见,尽管大家都说bikesdirect的saddle很烂。
最烦的是这个saddle只是靠一个螺丝固定的,时间长了就会松要翘起来,这个很烦人,
我基本每次骑长途中间都会松(上个周末的那个倒没给我添篓子)。得找机会换成两个
螺丝固定的,好像还要去换seatpost(座位下面的那根杆子)? |

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.

f**********e 发帖数: 1994 | 28 谢谢。现在的轮组是 Ambrosio 替 Bianchi 做的,不是太轻 (weight weenie 上说
~1750g) 但还过得去。有钱了再上 neuvation. seatpost 是该换 -- 比所有其他的
sp 都重了近 200g。saddle 在这车上实在是丑得出奇,但是我又比较习惯坐他了...
还有一我想到的减重目标是 crankset. Centaur 的 alloy crankset 近 900g
重,随便哪个 carbon crankset 都比他轻近一磅。

n******d 发帖数: 3583 | 30 这个好像真是麻烦了,反过来,多上下甩甩看有没有用,要不去本地的车店问问。不过
比较困惑,我用的seatpost一般一头都有夹坐垫的东西,你这个就是一根管吗? |

家LBS里最便宜的,我骑了三年,用他racing了一年。当然现在被我换的只剩下
Seatpost, Seat and brakes是原装,呵呵。
最重要的还是先骑起来,享受这项运动带给你的乐趣,以后有钱了再升级。 |

b******n 发帖数: 1269 | 33 Notice the technical sections have the seatpost lowered about 3"-4". So the
equipment should have been adjusted (probably replaced/repaired) many times

y*****y 发帖数: 3433 | 34 小朋友越来越重了,拿trailer已经快拖不动了。

b******n 发帖数: 1269 | 35 It certainly is, plus having such a tall seatpost plus long and low stem
certainly doesn't hurt. |
|
h******2 发帖数: 1498 | 36 That's pretty damn good, considering that you don't need a seatpost and
collar. How's the stiffness? Is that an asymmetric head tube? BB30? |
|
b******n 发帖数: 1269 | 37 And a really shitty cable job apparently. Boat anchor seatpost so shouldn't
be a high end model, but the Brooks seems a bit luxurious... A good one. |

h******2 发帖数: 1498 | 38 My vote:
Straight fork? Yes
Oval ISP? No
Outside clamp (not light, and ugly)? or internal mini seatpost (pretty, but
even heavier)? Internal
Aero tubing? Round tubing? Round tubing. Aero tubing looks too much like a
Cervelo wannabe.
Now the question is, what's the color for the frame, and what paint scheme?? |

Internal cable routing
rear shifting cable through dropout
1cm taller headtube than otherwise (saves a spacer)

expensive to make and unless we sell a large number, it will be financially

to tell them no. Same reason for size 50 shoes, etc. I am working on a

h******2 发帖数: 1498 | 46 yes, to a certain degree. it's a trade-off: you save money by using a
conversation seatpost, at the cost of compromised stability and handling. |
|
h******2 发帖数: 1498 | 47 yeah that's always a problem, steel or carbon. the only difference is that
if it's steel you can somewhat repair it, and if it's aluminium it's still
more error tolerant than carbon. if it's carbon, especially in the case of
seatpost, the room for error is much smaller.
