davey1991 Posted June 4, 2011 Report Share Posted June 4, 2011 (edited) Right this doesn't cause any shifting issues but i'm sure its not right. When i'm using my granny ring my chain rests on the outside of the rear mech for the first few or last few gears i can't remember of the top of my head, but it doesn't look or sound right. I don't mean it rubs on the inside of the mech but it acctually rests over the mech. I'm assuming my chain is to long? I don't think the chain has been changed since new so could this be halfords error? Edited June 4, 2011 by davey1991 Quote Link to comment Share on other sites More sharing options...

haydon_peter Posted June 4, 2011 Report Share Posted June 4, 2011 I suspect you are shifting into the smaller cogs in your cassette while in your granny ring, you should not do this. If you are using the granny ring and needing a higher gear rather than shifting all the way down the cassette you should be shifting into a larger front chainring.

haydon_peter Posted June 4, 2011 Report Share Posted June 4, 2011 Yep, you're doing it wrong. See my post before your photos. You shouldn't ever be shifting into those combinations, it will cause the most amount of chain slack and also create a bad chain line. You also shouldn't ever shift into the largest front chainring and the larger rear cogs. Quote Link to comment Share on other sites More sharing options...
JD™ Posted June 4, 2011 Report Share Posted June 4, 2011 Plus your chain is probably a bit long anyway. Chuck it into the largest cogs front and rear and get the chain to be short enough to make the rear mech face forwards at a 45 degree angle. Sorted.

davey1991 Posted June 4, 2011 Author Report Share Posted June 4, 2011 That was one option i thought of, i don't use them in fact i rarely use anything but my miffle ring but i noticed it the other day when i was setting up my gearing. Thanks guys panic over. Looks about right to me? Thanks guys. Quote Link to comment Share on other sites More sharing options...

trialsmax04 Posted June 4, 2011 Report Share Posted June 4, 2011 The main problem is the fact you have a short cage mech. Usually a 3x9 or 3x8 gear set up requires a long cage mech, that offers a greater range of tension over the large range of gears. Short cage = 2x9 or 1x9 really. 1 Quote Link to comment Share on other sites More sharing options...
