Triban 3 chain rubbing?

[Alembicbassman]

My 2300 Shifter on my Giant Defy has trim settings, just a small click to shift the mech enough to allow the chain to pass freely. I do not use small chainring small spocket or large chainring large sprocket. 2300 is entry level, my 105 Compact double is much slicker but then it's more than double the price of 2300. Horses for courses really.

You should not need to touch your limit screws. This is only required if your chain is dropping of the most extreme cogs and if set up correctly when the bike was bought will not have changed.

thats the crucial bit. I am a big fan of Decathlon and the guys there but the 2300 FD on my sport 1 rubbed ever so slightly when i rode it properly hard for the 1st time . I used the destructions on techdocs to set it up/tweak it and it has been perfect since

It was quite an expensive bike which is why I am not best pleased, otherwise I would have understood.

expensive bikes doesn't mean will be set up correctly. you would like to think so but not always the case.

Think I got it sorted, had to increase the tension on the front derailleur cable. Pity about the weather now.

The smaller frame sizes 45 and 48 have different front derailleur that the rest of the frame sizes. I got a 48" frame and was getting the same problems with the low and high gears (all on correct coggs no big cogg to big cogg etc ). i was told that it is due to the front derailleur is smaller. Complained about this and they are going to swap it for the larger one on the bigger frames.

most tripple setups are going to run im certain gears, just have to set it up so it doesnt in the gears you use most. mines set so i can use the highest gears with no problems. its caused when the chain is at its most extreme angle

Why would you want to run the largest chainring with the smallest 3 on the cassette?? Off the top of my head (IE not knowing what cassette you are running) only the 3 largest cassette rings won't duplicate the gearing available in the middle chainring.

I was going to say to try increasing the tension slightly, so that the derailleur moved a little further outwards. Im forever tweaking my gears like this, but you need to get it just right otherwise itll rub when in the larger rear sprockets and when youre in other chainrings.

That's good info, my Son's has the same problem and I just can't seem to get it set-up right.

My girlfriends had the same issue, the front mech was mounted too high on the seat tube and no amount of adjustment would cure the issue.

I was aprahensive of whether the gearing would be any good on such a cheap bike but it works great for me
