发帖数: 3290 | 3 Can't remember. It's all Shimano stuff. Crank is 105. BB is probably the
same level or maybe one level better. Sounds like it is important. I also
worry that if I don't get the torque in the specified range, it will affect
performance or becomes a source of some noise. But, I once watched a
technician in a LBS overhauling by crank. I don't remember he used a torque
wrench. Just want to know better about these things. |

them a torque wrench is not necessary. just don't use any cheater bars when
you tighten.

发帖数: 3290 | 9 有点没太搞清楚这个size的问题。Do I have to buy one for each size? Or, I can
buy a torque gauge and use it on any size? Never seen one and can't tell
from the online picture. How does a torque wrench work exactly? Thanks to
weatherx's comment, I don't have a plan to buy one for now but want to have
the knowledge in case I need one in the future when I get more money for a
high end bike. |

发帖数: 4396 | 10 on a bike the torque is generally low and there's little need for ratcheting
, so if you really want one, the recommendation is a 3/8" drive beam-style
torque wrench. the torque range is on the order of 50 inch-lbs to roughly
500 inch-lbs. a set of hex bits.
so for example, a cheap set would be sears items 00944690000 and 00910058000
.

发帖数: 159 | 12 I got a pair of torque wrench for around $150. in-lbs and ft-lbs. I use them
on both my car and bikes. It is a good investment cause tools last long. |
