Hi to all the fellas out there i need some help/advice on my group set..Ok i am not a spastic when it comes to bikes I can change a tyre in under 4 minutes and also change my casette etc( but im not good when it comes to adjusting the gears etc) I was hoping someone can give me advice on my noisy bike.. its not that the gears need tuning as they are changing perfectly! It's got worse since i have been here and i am running a durace chain on a sram red casette i know they are very noisy compared to durace, but its not just the noise its actually like each link is rubbing or very un-smooth...i dunno if its cos of the chain not being sram...but i dont think so as the noise was not there two weeks ago when i got my new chain..hmmmm or would it be the jockey wheels rubbing on something or loose?Also my casette is not loose either!!..Please help me as it feels like my chain is clunking and clincking its noticbly louder when i go slower and no its not the gearing either.... it also happens in every gear!arghhhhhhh help !!  |

Hey Bek,
Yup, SR is VERY noisy in comparison to DA. Something to do with the hollowness of the cassette creating an echo or something, can't remember exactly. As for the chain, DA chain is fully compatible with SR. I know there was any issue with the parrallelogram on the rear derailler, and something about a 1mm shaving needing to be made to it. But I thought it was only on earlier models, and had been sorted out already. I know a couple of guys who just swopped it to a Force rear derailler, and it sorted it out.
Otherwise, I assume you have been using a lube on the chain? My Dad had a similar problem with a motorcycle chain a few years back (since then he only rides shaft bikes). It was a new chain, but the lube had leached out in transit and while sitting on the shelf. All it takes is leaving the chain to soak in some citrus degreaser for a couple of hours, and then leaving it in some good quality lube overnight. In the morning, wipe of the excess, and put it back on. Then give it an extra coat of lube every day for about a week. Thereafter, back to your normal routine (weekly or fortnightly, depending on how dirty it gets).
Hope that helps.

ok Jamesi is officially 'the man' ...we looked and prodded and looked some more...casette ' nope doesnt feel loose' ...BUT upon closer inspection it was loose and you can really only tell by tightenening it up with tool, if u try to wiggle it like the shimano it doesnt feel real loose as its a one piece casette....problem solved i hope  |

Hi Bek! The record for changing a tyre is something like 48 seconds ... - with covered eyes.

FWIW, doing lots of big gear low cadence work can put lots of torque on the cassette and it can loosen over time. I had a shimano cassette literally come apart in peices on a ride where I was no where close to a bike shop. Had to stop every 5 miles or so and hand tighten the locking ring until I got to a BS.
Bike shops like to use those torque wrenches that tell them to stop at a certain number. But sometimes that number may not tighten it enough. Its a CYA thing for them in the event they break something. Suffice it to say I now carry a cassette locking nut in my saddle bag in the event it happens again to me. But I do check the tightness periodically especially after big hill sessions.

bek has tried a few brands , not just aussies, and she has found them, to be less than adequate,
the older i get , the more i tend to agree

Yes, bek has some stellar legs. They will squash many girls dreams this year. My legs are very envious and quite intimidated. After my legs are next to bek's for awhile, I end up having to give them a pep talk...maybe we can manage a way to simply detach bek's legs and pass them around the team.hey, where my keat's at?!
