CycleOps has dropped the price of its popular PowerTap G3 power meter hubs
down to $789, from $1,299, effective immediately. Its Joule and Joule GPS
computers see a decrease in retail price as well, down to $99 and $219 from
$169 and $269, respectively.
The 40-percent drop in the price of the G3 hub puts the PowerTap system into
the same ballpark as the least expensive power meters on the market —
notably the new Stages Power meter,... 阅读全帖 |

发帖数: 1994 | 2 今天终于用 $480 (卖掉了 Fender Strat, Marshall amp 来筹资）
买到了 Powertap. 那 $15 是用典型 craigslist 无赖杀价法砍的 --
老子钱就这么多，爱卖不卖。那老白一皱眉，还是卖了。花了 1 小时装，
（移 cassette, 轮胎，装轮子，走线），跳上去骑 trainer... 哇靠，
240W 耶！心率还没到 80% 耶！我能和 Al-sultan 有一比了耶！
嗯... 不对... 我不踩时咋还有 20 Watts 勒？ 结果发现 hub 的
torque 要归零。一归零... 180W。
唉。咋就不能给我做点好梦呢。不过还是有点收获, 本来我以为是 150W 的
workout 原来是 180W, 那 setting 3+20mph "180W" workout
其实是 210W. 再者我发现不管我以为自己踩得出力多均匀，都会有一个 power
spike.
我自己一直觉得骑 trainer 实在很像是看 XXX 片打飞机, 就是不对劲。不过
现在孩子还小，估计我得还要打好一阵子飞机。Powertap 会让 traine... 阅读全帖 |

发帖数: 1992 | 3 这玩意利润很高，所以大家都想进这市场。竞争多了就要降价。
Powertap其实本来就很便宜了。俺当年$500进二手powertap的轮组，ant+直接连上
garmin，跑了接近两年，7/8千mile，啥问题都没有。现在二手是不是$300就能搞定了。

发帖数: 60932 | 4 For those of you who have been looking for the top of the line Powertap SL+,
this retails at $1395! this is a screaming deal for the capability it gives
you if you're a pro or training for a race, criterium, etc. This also comes
completely built on a rear wheel of your choice (the standard wheel is free
and does not change the cost). At $695 this will not last once word gets
out.

照着 trainer 的 power curve 骑 (码表装后轮）。如果要 180W, 就放 setting 3,
定在
20mph 就行。但是有 PT 还是比较爽。

发帖数: 1994 | 9 现在在市面上就只有两类：装在 Crankset 上的 (SRM, Quarq)，和装在 hub 上的
(powertap)。那些“间接测量“的方法 (polar, ibike) 我都忽略不计。Garmin
vector
要到明年才出来，装 BB 上的 ergomo 已经歇菜了。
SRM/quarq: 贵，工业标准，不需要迁就轮组
powertap：相对便宜，选择多，但需要迁就轮组
广大 wsn 们还是挑便宜又大碗的吧：wired 的 powertap。二手的 350－400 搞定。 |

发帖数: 1498 | 23 trainer质量很好，非常稳定，噪音低，骑起来很像在路上骑，而且比spinner更逼真（
spinner的阻力是靠摩擦的）。
值的一提的是这个trainer配了一个power meter，可以显示功率，误差应该在5%之内，
非常consistent。今天小试了一把发现可以保持在210W左右。

The one that you'll be riding the most.
If the $39 difference matters to you, the $660 one.
Nope. Unless you join a team and get some shop-specific discount, or get a
used set from Ebay. |

发帖数: 1498 | 35 The wheel new costs about $600. So the guy spent just a bit over $100 and
got 2.5k miles out of it.
Now if you use that as an amortization schedule, will you be able to get 12.
5k miles out of it? Probably not in 3-4 years, unless you're riding 5k
miles a year.
But, on the other hand, if you buy a new wheel, it's even less likely you
will put 15k miles on it in a few years.
So, I say it's not a great deal, but fair enough. Now if you can bargain
with him to get it down to $400, that'll be a ... 阅读全帖 |

here are the reasons you should ride
(1) family dudes -- car is much more dangerous, I feel much safer in a
group. so don't follow too closely and you will be fine.
(2) tri dudes -- you know they say some group rides can make a tri-dude
less lame...;)
(3) anti-social dudes -- drop the whole group or win every county line
sprints is the best way to show your anti-social attitudes! |
