"Pouring cold water", much effect of an aero wheelset is psycological. You "
feel" you are fast when you ride an aero wheelset, but study has shown that
an aero helmet reduces power required for a timetrial much more than an aero
wheelset does.

发帖数: 1992 | 2 my weight: 165-170 lb
riding style: for fun, mostly. no race at all (simply because I'm not
capable of). A typical ride to use the wheelset would be a day trip to the
coast and back, around 100k to 100M, with elevation change from 6k to
10k feet.
I guess I need a relatively light wheelset to ease the climbs, and stable on
downhills with cross wind. It needs to be easy for me to do minor on-the-
road fixes.
budget: $500-$1k
Any suggestion?

发帖数: 19210 | 8 这就是碳轮，只不过它的最外圈是铝的（Aluminum Clincher），而不是全碳 Full
Carbon Clincher。
这个介绍写的比较具有欺骗性，因为＂Aerodynamics - time and watt savings over
40K for 404 Firecrest Wheelset: 80 seconds / 27 watts. ＂是用404 Firecrest测
出来的。而404 Firecrest只有Tubular（全碳）和Carbon Clincher（全碳）版。

当然404铝Clincher仍然是好轮！花花上次买的好像就是这副。

发帖数: 4394 | 33 fens用了几个月了，还行。更正一下，fens的hubs，brakes，bb，crankset（方轴的）
都不是105.不过也还好了。wheelset用的是da22+formula,很低档的轮组，比较重（不
包括快拆~1900g），ture过两次后轮（买回来小调一次，爆胎之后跳过过一次），后轮
2-cross，如果是3-cross可能会好一些。车座太宽，太软。需要好好调一下变速，尤其
是前拨。cable也需要重新润滑。总之，还是性价比不错的。如果动手能力ok的话，能
把它调成很理想的状态。 |

我目前的轮组是Alx a320comp。平时上下班用。http://www.aclass-wheels.com/road_alx320COMP.html 跑了
6000 mile不到，除了感觉沉了点以外，其他都还不错。前轮5000麦以后有点点歪，但
还不到需要true的地步。
现在想进第二套轮组周末骑着玩用，比如跑跑century啥的，上坡也省点力气。希望能
容易维护，比较轻，下坡稳定。看了
下，有几个选择:
1. williams 19, $500 (williamscycling.com) 这个好像版上不少人推荐
2. Shimao dura-ace 7850-SL, $550 (bonktown.com) 这个好像可以用tubeless的轮胎
，也兼容tube+tire

发帖数: 1498 | 45 I don't have experience with the DA or Easton sets, but Williams system 30
might be a better choice than 19, because the 30mm rim is more durable than
the 19mm one. For the type of riding you do and the price range you're
shooting for, the weight of different sets are in the same ball park. You
can't go wrong with any of the sets above.
I wouldn't worry too much about the weight -- assuming that your bike is not
an ultra-light one.
