我猜下一個就是蘿蔔車隊!而且是9070!
這個計時車後叉專用的direct mount version brake, 還真的像U-brake............





Another new product in the DA9000 line is the BR-9010 brake, a “direct mount” caliper. Drawings within the document describe a caliper brake that mounts with two bolts similar to the aero brakes found on some time-trial and triathlon bikes.

Other details:

- The following ring combos are listed for DA9000 cranks: 53-39, 50-34, 52-36, 52-38, 54-42, and 55-42.
- There is no triple option.
- An 11-speed compatible bar end shifter will be offered.
- The group contains a new 9000 series SPD-SL pedal.
- The document describes two mechanical disc brakes, compatible with Super-SLR levers. The BB-CX75 cyclocross disc brake and the BR-R515.

讓我比較驚喜的是UL Di2竟然也可以升級韌體變11s
如果真的開放韌體升級,那UL Di2真是通包又用好用
敗家是無止盡的...囧rz
11S 52-36 / 11-25 好像滿不錯的
跟 10S 50-34 / 11-28 相比,最大齒比更大,最小齒比小輸,
齒比遞移更綿密 (大盤約 0.25 一檔,小盤 0.17)
飛輪的 25T 改成 26T 就更好了

DuraAce 後變有支援到 28T,猜想未來 Ultegra 和 105 會更大,到 30T?甚至 32T?
來顆 12-30 飛輪吧 (12-13-14-15-16-17-19-21-23-26-30)
52-36 跟 12-30 配,最小齒比小贏 34/28,非常好爬坡,最大齒比也只小輸 50/11
或者弄個 11-32 飛輪 (11-12-13-14-15-17-19-21-24-28-32)
50-34 跟 11-32 配,最大齒比非常大,最小齒比非常小,超讚
不知道重量又減輕了多少呢?

變把看起來很好握,像7800碳纖內線化
