certainly doesn't hurt. |

发帖数: 1269 | 2 You are probably right. Occassionally they hate having too short a front
center, so they use negative rise stems, but most people just have custom
made frames that are low and long.
don'

a smaller frame plus a long stem, would improve the overall stiffness of the
bike. So they are trading off stiffness for a better riding position? |

发帖数: 1498 | 3 Just ordered a Newton Shallow, will let you guys know how it feels.
Now I realize that my current frames are one or two sizes too small -- they
are 53/53.5 top tubes. I'd like to ride a 55 or even a 56, with zero or 1
cm stack height.

发帖数: 893 | 5 does your lbs offer rental service? maybe you can try out both sized before
you buy. you can also buy a $20 adjustable stem just to play with positions
more easily before you decide on a particular size/stem combo. you are
taller than me and I ride a 56.
I thought your khs is a 56, isn't it?

发帖数: 893 | 6 as I have stressed before, any measurement of toptube on a road bike must
have a reference of 73 degree seat tube angle. 73 degree is a neutral hip
position for maximum power and comfort, one people shouldn't deviate too
much from. for our height, one degree generally translate to one CM. this
means
56cm measured TT length with a 73 degree seat angle is the same as
55cm measured TT length with a 74 degree seat angle.
if your seat tube angle is too steep, you should try moving the saddle back

发帖数: 1498 | 7 both the dale and pedal force frames have 74 st angle, that's probably why i
ride 53/53.5 tt and don't feel too squeezed. i guess the next frame should
be a 73/55. |
|
h******2
发帖数: 1498 | 8 btw, victoon, if i move back my seat on a 74 frame by about 1cm, doesn't
that create an effective 73 seat-tube position (with the effective TT
extended by 1cm)? in other words, i can create the same geometry of a 73/55
frame by moving the seat back by 1cm on a 74/54 frame. the only difference
would be the shorter wheelbase and more backward center of gravity on the
74 frame, which might result in some subtle handling differences, correct? |
|
b******n
发帖数: 1269 | 9 more like 0.7cm... but that's the idea. In fact the wheel base should not
change much.
55
difference |
|
V*****n
发帖数: 893 | 10 54cm tt with 74 st angle is exactly the same frame as 55cm tt with 73 st
angle. the only difference is the first allows you to seat more forward and
the later allows you to sit back a bit. and normally the first one is marked
as a smaller size with a shorter head tube. you should read this if you
really want to understand this.

发帖数: 893 | 12 I think a 56cm tt with 73 st angle will suit you fine. and if it's longer

能用手不太费力的板紧就好。
tube的上沿不能高于stem，比stem低 0.5-1cm.如果你觉的handlebar还是太低，可以把
stem翻转过来安装。
还是买自锁鞋吧，spd兼容都可以。平时不想用自锁鞋，那个小踏板也可以用。

but i think it's totally possible. i was riding my old road bike on a much
higher saddle post. then when i
bought my Cinelli, the shop did a quick "fit" for me, and i was surprised to
find how much lower the saddle
should be. definitely more than 1" lower.
but i'm still riding my mtb on a higher saddle than my road. not sure if i
should lower it too. definitely need
another bike fit.
handlebar angle? what's the correct angle? should it be fitted for everyone
differently? |

hydraulic systems instead of cable operated brakes to simplify the bike

发帖数: 1501 | 20 安全木有隐患，只要你的steer tube的上边缘比spacer的上边缘稍微短一点就行。锯掉
的好处一来是可以稍微轻一点（这点重量，估计也不会有显著影响），二来是看着美观
一些。锯掉的缺点一是你以后要是想升高handlebar比较困难，二是如果你要卖车，或许
有的买家不喜欢把stem放低，会给你卖车带来一定局限。 |

I like it very much. You may check the review online. My impression:
- climbs very well and feel a lot easier than my wife's Motobecane 700HT.
- shifts extremely well. Now I really believe in SRAM stuff. It's a 3x9
speed bike, which is exactly what I want (for touring, more durable than 10
speed).
- decent wheelset.
- decent folk. It's only 80mm travel but I like it better than 100mm travel
for the type of ride I do.
- OK brake. I might eventually change it to mechanical disk brake before a

发帖数: 19210 | 36 原配是80mm -6°的stem，fitting过程中试过90mm和100mm，最后决定用90mm -17°
的stem。
主要的调整有saddle position （higher and more forward），handlebar position
（需要一个新的stem，10mm longer，more angle -17° vs. -6°），还把stem下面的
spacers都去掉了。另外还在鞋里加了wedges。
在fit前，我的position大概介于粉人和黑人之间，现在应该是个纯黑人了。;-)
