Have you ever had perfectly-adjusted derailleurs?

[themosquitoking]

My front derailleur on my best bike isn't 100% but the rear one is spot on, my commuter now has a spot on rear after a bit of fettling the last two days, haven't used the front gears on it for a week or so so judgement on that is reserved.

In the 4 or 5 years I've had my Boardman, the SRAM Rival has never needed adjustment. No mater what cassette I've fitted to the original or the Zonda upgrade wheels the rear dérailleur has never needed adjustment. The front dérailleur has also never needed adjustment apart from when I had the chain rings replaced. Smooth as silk in operation, they just need to reduce the loud clunk when changing down on the front.

This just gives me more time to spend adjusting the Shimano 2300 on the Triban which has never been smooth in both directions - it either changes up or down perfectly but needs work in the other direction. The Tiagra on the Kona works, but needs fine tuning with cable tension occasionally.

Yes since I fitted some 105 triple kit.

Not sure why changing chain rings effects the FD position.

If you change the size of the rings the FD may need moving and cable adjusting.

There's something wrong with that, mate. I'd take it back and complain.

He didn't say that he said replaced (which for all of you using the Americanism "swap out" is correct as is just swap, you don't need the out) , if you change ring size you would need to move the FD up or down the seat tube to get it set for optimum shifting.
Sorry being a bit finicky

Ive had a horrendous issue with my sram red recently ots been clicking and skipping no matter how much i adjust it the chain cassette wheel and mech is fine so ive no idea what the issue is infact ive. Hecked all the components and wven re cabled it, even when it was working fine i can say it wasnt as smooth as my £70 mtb with tourney infact when i test rode dura ace it didnt change as smooth on the rear as my tourney! As for the front shifting on my sram red well... It will shift to the big chainring once after being adjusted then never again!

I have Red and a rear derailleur issue is driving me crazy. I can index it so every gear it silent, it's perfect - then 40/50 miles later it's making a noise in some gears. It's cabled as per the factory and has never hit the deck so I'm at a complete loss as to what's happening for it to move out of line. My old force rd was perfect and I never touched it. I can't stand any funny noises coming from the bike so constantly re-index it! I'm going to have to change the cables just to see if anything is at fault there.

The Red FD relies heavily on cable tension to work properly, Sram needs to be much tighter than other systems ime. My front shifting is absolutely spot on, but even though I have the marks lined up exactly right I still get a bit of rubbing in the big ring and biggest 2 cogs. It's not really a problem as it helps stop me cross chaining.

I don't get that on my triple, i might have to trim it, but thats what the function is there for, I can use all 10 on the back with my middle ring which with the current set up gives a range from about 37-87" pretty much most of my riding, but the shift from the middle to outer is sweet, from inner to middle not so clean as i am currently running a basic dural 40th ring, it shifts ok but not perfect but noiselessly even so.

Another one for yes - always. Gears are easy once you know how..Front triples can be a pain - the secret is in reducing the gears that you use so that the chain is always straight (small front chain ring to larger rear cogs (sprockets), middle front to middle back and larger front chain ring to smaller sprockets) Chain hanger alignment is also important. Front triples are easiest when there is no indexing and my thumb shifters give me an on or off option.

 

[Kevoffthetee]

Yes, the gear changes are seamless on Le Pug as I took my time on getting them perfect. I also try not to change gears when I'm not pushing too hard

Until last night I'd had great shifting for the whole year I'd had my bike (Second hand Trek 1500 w/ 105) with no tinkering at all. It fell over and landed on the real derailure yesterday.

What a perfect excuse for an upgrade...

I took it to the LBS today just to see if they'd quickly check it for me (I'm going away to Uni on Saturday so I wouldn't have given them my bike to do the replacement). The owner gave it to the mechanic (both top blokes) and he just straightened it for a few quid into the charity pot; it shifts better than ever now. I'm well chuffed.

That's a bugger. They might have told you you needed a new bike...
