cas247 Posted November 20, 2014 Posted November 20, 2014 Hi Guys Help would be much appreciated. Whenever I down shift from the big ring to the small ring it tends to fall off. It happens on the flats and will definitely happen when climbing. It's rather annoying as I have to down shift when I'm going downhill in order for the chain to not slip off. Any ideas how to stop this from happening? I've seen a gadget call a 'chain catcher', will this help? Ps. I've taken my bike to my lbs multiple times and they always say the gears need adjusting, which they say they've always done but it seems like it's just getting worse. My groupset is Ultegra 9 Speed. Standard 54/39 chain rings
fanievb Posted November 20, 2014 Posted November 20, 2014 you need to adjust your lower limit screw on your FD. Mine did the same, now its almost rubbing when I'm in granny http://www.parktool.com/blog/repair-help/front-derailleur-adjustments
David Marshall Posted November 20, 2014 Posted November 20, 2014 Also check that the FD is as low as you can get it without it touching the chainrings and that the outer edge of the FD cage is parallel with the chainrings. Setting the front derailleur, especially with a triple, is not as easy as the rear. Give us a shout if you don't come right.

Do you guys know of a store with a brilliant mechanic in the Sandton area?
venom1 Posted November 21, 2014 Posted November 21, 2014 There are some great online videos. When you see the video you will have a better understanding of the above mentioned.
cas247 Posted November 21, 2014 Author Posted November 21, 2014 It's a road bike. Throw it away and get a MTB. No need to thank me. I have a road and mountain bike, I love MTB'ing, been a MTB'er for 6 yrs or so and doing road for a year.. However the vibe @ road events is quite something
Bomberman Posted November 21, 2014 Posted November 21, 2014 There are some great online videos. When you see the video you will have a better understanding of the above mentioned. What Venom1 said works, had the same trouble with my road bike. Watched a few vids on youtube and got it spot on. No cycle shop needed.
LeTurbo Posted November 21, 2014 Posted November 21, 2014 Sounds complex.... Definitely not. You can do it with your multitool, and it'll probably take all of 3 minutes. OK, 10 at a push. Getting to and from a bike shop: 1 - 2 hours, plus costs.
droo Posted November 21, 2014 Posted November 21, 2014 Sounds complex.... Do you guys know of a store with a brilliant mechanic in the Sandton area? And the winner is...

'Dale Posted November 21, 2014 Posted November 21, 2014 Chain could be stretched How many myle on that one?
BMXER Posted November 21, 2014 Posted November 21, 2014 Set your front derailleur correctly and fit a chain catcher just in case.
cas247 Posted November 21, 2014 Author Posted November 21, 2014 Tx for all the replies guys, I'll give it a try this pm
