Now we need FNG to post something other than a Cannondale so we can move on.

[ProCracknfailBro]

I don’t even know where to post shit

[turpentine]

if you try and make a new thread and the forum thinks it exists it will tell you.

But what about the spring in the front derailleur?

Springs can be thought of as compression (push on it to make it shorter) or extension (pull on it to make it longer). FDs have torsion springs that are pushed on the make the coils tighter.

To upshift the pull of cable tension is coverted to a push by the lever arm. To downshift the spring pushes the mechanism back down.

Mods please change term derailleur to pusherman

new guy does have at least two very cool bikes that aren’t cannondales

NATURE ABHORS A PULLER

[rabbi]

[turpentine]

everything is just a push with different geometry.

[Master_Stabby]

Pretty sure they were talking about rapid rise pushers.

[LASER_BEIGE]

Pulsh

[Bootus]

pull = -1 * push

[Mankato_Pet_Cremation_LLC]

pull * (1/push) = 1 /((i)^2)

WE’RE KILLING SHELDON

@Grant

The thing we’re talking about derails the chain, so I’m sticking with Sheldon, and why not? He was so smart, funny, interesting, humble but confident, kind, such a bike lover and educator, and as much as he contributed to bicycle knowledge all over the world, he died too soon (2/4/2008) and could’ve done so much more.

Keep him alive, figuratively, with derailer!

@Bootus

pull = -1 * push

different geometry sign convention

That TT is incredibly thin walled- it’s a pretty outrageously awesome tubeset. I reckon the frame cost is twice that of an Allez and maybe 3x that of a Domane ALR (cheap bike that plays cheap tricks to look fancy, and does it well).

Doesn’t this just mean that T and S are better at cutting production costs than you? Since higher costs don’t necessarily mean higher quality. What are some aspects to the CAAD13 that make it a better frame aside from the dropped stays?

[turpentine]

the allez looks like a caad 10

To upshift the pull of cable tension is coverted to a push by the lever arm. To downshift the spring pushes the mechanism back down.

Note that this makes the spring a “Push Battery”. It stores the push of the upshift to push the chain back down.

…ut yes, people are not fond of the seat tube junction weld, which I understand. That TT is incredibly thin walled- it’s a pretty outrageously awesome tubeset. I reckon the frame cost is twice that of an Allez and maybe 3x that of a Domane ALR (cheap bike that plays cheap tricks to look fancy, and does it well). Alas, joke is on us because some people don’t even throw a leg over it because of a weld.

does it squish?
