    I have an 2010 secteur triple..las time I was out on it I was having trouble shifting up on the front chain rings...it got to a stage that the shifter itself was getting very stiff to move..I was knackered after the ride so it went straight into my garage..having read up here on what it could be..it sounds like the cable needs more tension..i'm out on a ride tonite..so need to get home and do this...the bike spec sheet says I have Shimano STI 2300 shifters..but the video tuturials with these one look different than what I have got....mine have the little levers on the inside of the horns which do opposite what the brake levers..the videos show another lever behind the brake lever...what I want to know is where do i adjust the cable tension?

    You're levers sound similar to the Shimano Sora levers, so try searching for that instead.

    You should have tensioners on the down tube, where the cable housing stops.

    Try there. If not you'll have to disconnect the cable from the derailleur and do it by hand.

    Try one of these videos

    It doesn't matter what levers you have, it's the derailleur that needs adjusting.

    You may also need to adjust the limit screws to stop it going too far. But try the cable first.

    ive adjusted it via the cable adjusters on the downtube..it does go up the rings...just about.....small to middle is worse....its giving it a really good thinking before it decides to finally move up the ring..middle to large is ok.....but.....it now wont go down from large to middle..when i eventually get it down..its straight into the small ring

    Sounds to me like a new cable required, its probably frayed inside the outer and jamming up. disconnect from front mech and try shifting while you hold the end to give a little tension . If its stiff there's your trouble, if not on to stage two.....

    If the shifting is stiff then it doesn’t sound like an adjustment, click into smallest ring, disconnect the cable from the mech, then you can then feel if the inner cable is running smoothly through the outer casing. If it is then pull the mech with your fingers to see if it’s free, the pivots can get quite stiff especially after the harsh winter on treated roads. If the mech’ is stiff lube pivot points and keep pulling mech’ across by hand and letting the tension pull it back again; keep doing this and and often it free it up again; same applies to the rear.

    If only six weeks old take it back, the dealer should correct it.

  10. I did this with mine after a couple of weeks,front shifter definately not as smooth as I would like,but think a lot of it is down to technique,once I'd mastered the 'trimming' it made changing up a lot easier/smoother.
