Vehicular Cycling (VC) - The big flaw of VC

He's made some good contributions too -- to these fields and others.

What he's referring to is "trimming" the derraileur, HH, and it ONLY works with Friction shifting.
I know how to trim a derailleur, Tom. :rolleyes:

In the cases I've seen, it comes down to chain stay length and chainline. On a bike with short chain stays, sometimes you just can't get the chain to not rub. If you do, the bike won't shift right between chainrings (just went through this last weekend after installing a compact crank for someone). The offset between the chainrings and cassette plays a part in this too. If one of your chainrings is more centered on the cassette than the other, the more centered chainring will be easier to adjust for no rub at the extremes.

By the way, my DA STI shifters do have the ability to trim the front derailleur, but not in the infinite number of positions that my 70s Campy Record pure friction shifters can do.

I was just shooting you the word you were looking for, not saying you didn't know how to do it, HH;)

maybe Hed's derailleurs are not adjusted properly??? :roflmao:

cross chaining does not automatically result in derailluer rub or cog/ring noise.....

and now back to our regularily scheduled VC programming....H. Head arguing minuatae and insisting he's got the anwsers, to the detriment of the topic at hand....


Maybe time for a Headpoll about derailleur rub?

BTW, I don't know what you are talking about with this stuff, and I couldn't care less. AND I don't think it affects my ability to "fare" just as well as the HH and pals.

what's this about getting together to rub derailleurs?!?!? I am shocked, just shocked!!!


:eek:

Hello all. Gee, what an opinionated group. So here's the scoop. On my 10 cluster in the back (shimano) and ultegrra front and rear, i have the infamous rub on smallest front and smallest back. It wasn't always so. Just the last 600 miles or so (now at about 2200 miles). Last adjustment by bike stroe said nothing could be done. That seemed strange to me given that the bike wasn't like that when new.. Any thoughts?
Also, please enjoy the ride. Cheers.
