肝心の脊髄を守れてないね。意味ないのでは。ヘルメットの方が良い。

車に乗る時も良いかもしれませんね ハンドルのエアバッグだけでは不十分なケースが多いので

なるほど 全然分からん

For me, Shimano has the most consistent shifting performance hands down. However, I get confused using the same fingers to upshift and downshift, so I often misshift and destroy my cadence. SRAM is the simplest to shift, and its shifting is almost as reliable as shimano. I just don't like how the levers take a lot of effort to shift. Campy, they have the best ergonomics. I like how my thumb upshifts and my fingers downshift. I never mistaken my shifts. However, Campy's shift mechanism is unreliable. going from 4-5th cog sometimes works, sometimes doesn't. Poorly engineered, but for me, easy to use. I switched all my bikes over to Campy.

それ付けたまま遊んでて友達にふざけて叩かれて ばんって閉まるん？

Campy sucks.

campagnolo. only. the others are irrelevant. insignificant.

素晴らしい(￣▽￣)

campagnolo is better campagnolo campagnolo number one in the world

23:09 I like this part. ここいらが見どころですかね

アルドノアのあれ

Da9000 smoothest in the 4.

Campagnolo 🔝

Did you re-adjust your rear derailluer? It's seem not work smoothly.

Campagnolo devant !! les autres du gros caca

wow i could watch this for hours! da 9000 BOYEEEEEE

Sram all the way

E' molto utile il video.

i own a veloce....I know im poor

Campy mechanical group set is amount the best but no much difference compare to dura ace 9000 in terms of performance and durability. It's more like brand, image on the Campy and makes it so much expensive. Dura Ace 9070 Di2 is the best group set on the market now, and even better than Campy EPS as I tried both.

Wow, what a nice hair cut!

***** There is a significant difference between 105, Ultegra and Dura-Ace. I've owned all three somewhere down the line and the Dura-Ace shifter still feels as good as ever after approx 50,000 miles. The 105 and Ultegra both went at around 10,000 miles. This clearly indicates a quality difference in the shifter. The same will go for the derailleurs, chainsets and brake callipers.

campy as its best from the looks, performance durability and it will never easily degrade the value!!!!!

you cant compare the campy to others if you have campy just like youve own a ferrari or lambo....

di2's????...its nice,responsive..when its new.. what if after a year???battery problem,drain fast after several use....wires when you need to replace it after long time of use.... manual shifting.....cable problem???go to the nearest bike shop and buy...no need to worry about batteries,when the wires are dirty....... :)

The perfect group = shimano dura ace 9000 crank , sram red shifters , super record derailleurs. Each one special in their own wy

Campagnolo super record is the best groupe at the marked at the moment!

it a bit stupid you saying that cus ultrgra di2 and dura ace di2 are exactly the same the only difference is the weight so unless you race or are looking to save weight your wasting money ps(im a head mechanic at a bike shop so i know the systems inside out )

super record you mean?

Deklan, You're the first person I've heard of who doesn't love Di2. I've got 3k miles on it and it is flawless. What problems are you having? Most users say they'll never go back.

I'm looking into getting ultra di2. run me through what problems ur having

I have Ultegra Di2 and Its rubbish, I'm getting Dura Ace 9000 soon.

di2 to 9000 to sram red to speed record
