That's a very good point. The moment of the housing from steering would Definately effect the shifting long term....

Well thought oysters

Hi,



Not sure if that is what you meant but not using a spring (and yes you want a strong one) would definitely allow the adjuster to drift out of tune. That's precisely why those spring are there in the first place anyway.

BTW, regardless of front or rear, they both see more movement then you'd give them credit for really.
Especially so while downshifting a few cogs at once which temporarily releases the cable tension allowing the housing to move up and down as the derrailleur tries to catch up with the slack.

Ciao,

I think he meant ditching the adjuster altogether.
Certainly the twisting up front introduces a torque to the housing, it could definitely cause the adjuster to screw in over time. I've noticed the one on the FD cable of my road bike migrates. I'm gonna either put just a little Loctite on it or find one with more distinct detents.
Someone ought to come out with one that will only turn when you gently squeeze the sides. no more random turning then.

Hi,



Yep. An auto-locking mechanism of some sorts would be nice.
If the tensioning bolt/screw can wander (on the FD side) then the screw must be really far out of its retainer. The further you turn it the less the spring is tensioned which of course does nothing to help either.
I'd put a couple of small washers under the spring and see if that stops it.

Ciao,

great thread. would love to see more tuning.

Tiso Altore 366, swapped cage and removed 10 grams, will be more tuning öater with screw changes.

You don't know how much I want one of them!! SO FRICKEN COOL!!

Got pics of the original vs new cages?

Mattias Hellöre , did you use the cages from fibre lyte ?

I made them in my cnc mill. Took a while to make near exact copy of cages.

Pricing info mattias@hellore.se will not take it public here.

Original they look like that.


I made copies in carbon 1.5mm thick.

Thanks for the photos Mattias . It looks superb and the shape is really cool, quite funky and I like the fact it is something I have not seen before . AWESOME

have anyone done what mattias did with a dura-ace cage?? if that is possible it would be awesome!

When I tuned my SRAM red FD I thought about trying, but the way it mounts makes it damn near impossible for me to make a carbon cage. I believe if I have a serious go at making one it would have to be a pressure mold, with an adapted mount as the current cage is riveted on by SRAM....

I would love to see if anyone has tried it before though?

Off topic but how do the Tiso components shift in comparison to Campag/Shimano? Are they on a par or slighlty less? Often wondered, especially with matching them to Campag/Shimano shifters.
