|Record shifter driving me nuts again with rattle||Dog|
Oct 30, 2001 7:04 AM
|My left Record 10 shifter is rattling again. It's worse when shifted to the small ring, and much worse when I remove my hand from the top of it. The rattle can be worse than the Ultegra rattle that everyone is familiar with.
I can't figure it out. Last time it was bad, I found the front derailleur cable had come out of the channel under the bottom bracket, giving some extra slack in the cable. Not this time. I have the cable taught, even when shifted down.
The sound is so bad it sounds like a cheap piece of crap. Rattles incessently. Any ideas? How long can you expect one of these shifters to last? Seems like more than a year/10,000 miles would be expected. Rebuild it? Lube it? Replace something?
Any ideas would be appreciated. Thanks.

|I think directions are on the campy only site and also in zinn's maintenance book. if you don't want to do it yourself there are people who have done this many times. peter chisholm (the si parle campagnolo guy on rec.bikes.tech) at vecchios in boulder, co will do it if you send it there i'm pretty sure.|
|thanks, but it sort of irritates me||Dog|

|Should not have to rebuild this stuff, IMO, after only one year. Maybe I shift too much...
Almost tempted to just buy new ones. I'll not try the rebuild myself (I'm not good with lots of tiny spring things), and I don't think I'd be patient enough to send them off and wait until whenever to get them back on. Damn.

|But I don't think rebuilding would really help matters. Is the sound a low sort of buzz, or a more distinct rattle?
Shifters usually need to be rebuilt when they don't shift accurately any more- not because of some funny noise.
|almost just like the Ultegra rattle||Dog|

|It's as distinct rattle, showing up on rougher roads. Almost goes away when in the large chainring and my hand is on the hood. Worst when in small ring and hand not on hood. Trimming toward the large ring a tiny bit helps, putting some tension on the cable, but that doesn't stop it.
Come to think of it, the shifting performance seems to be degrading, too. It seems to be getting sloppier, requiring more trimming and over shifts, and more attention to get it accurate. Damn things. Sort of makes me want to keep the downtube shifters, pure friction.

|Do you think I know what an Ultegra rattle sounds like? Please, I would never stoop to the level of riding something other than Record, unless it was Dura-Ace.
I'm kidding, of course...
I think the below brake cable suggestion is a good one, check also to be sure that the brake shoes are not hitting the fork blades- thus not allowing the brake to fully open.
As for rebuilding, I know the inside of those levers better than I'd like to, and I can't think of anything that rebuilding would help. Also, the right shifter typically goes long before the left (I'm not sure I've ever seen a left need to be overhauled). Double check your housing, and ferrull situation- could a loose-ish piece of housing be allowing a ferrull to rattle around?

|Didn't mean to insult :-) No doubt you have ridden near someone else, a newbie/Fred type person, who had the Ultegra rattle. (I had the Ultegra rattle for 2 years, fixing it from time to time with a little electrical tape stuffed into the lever.)
I'll give it a good going over. Since no one else has experienced this, it is likely something unique, and maybe not the shifter itself. Thanks.

|I have 3 bikes with Record carbon blades, 1 9 speed and 2 10 speed. The left shifter rattles on all 3. None of my other Record 9 and Daytona 9 shifters with aluminum blades do that. I thought it was just something intrinsic to the design of the carbon blades. If you find an answer to your problem, PLEASE POST IT HERE! Thanks.|

|Did yours do it from new, or did it develop over time? Thanks.
Oct 31, 2001 2:31 PM
|I'm not really sure. I didn't notice it right away on the first one, but that may have been the result of being all excited about a new toy. The other bikes seem to have been doing it from the outset.|

|Dog, I don't have Campy, so take this for what it's worth. I had a brake housing slip out of my Dura Ace STI lever and it rattled like crazy. I slid the housing back into the lever and it's been quit since.|

I had a similiar problem with my left Chorus lever, but it turned out to be the brake lever, not the shifter. I had inadvertently overtightened the brake caliper pivot bolt (I have Daytona brakes - I know Chorus & Record don't have a pivot bolt head, but I think the nut is accessable from the back of the caliper) and the caliper was unable to fully open. This left about 2mm or slack in the brake cable and allowed the brake lever to rattle on all but the smoothest roads.
I loosened the bolt a smidge and the problem disappeared.
Hope this helps,
|thanks, that's worth checking nm||Dog|

|"up-shift" lever hitting brake lever?||Kerry Irons|

|There is supposed to be a small rubber bumper on the brake lever so that when (not if) the shift lever hits it, there is no noise. If this bumper is gone, you have metal hitting metal. Try riding the hoods with your finger just pusing the shift lever back a fraction. If that kills the noise, look for a missing rubber bumper.|

|There are no rubber bumpers on the carbon levers. After seeing this in another post I checked today while I was out riding.|

|I was mistaken. There is a little rubber nub on the carbon set. I was looking on the leading edge of the shifter, it's on the trailing edge of the brake. I checked again while riding. It might help if I looked while stopped not riding 20 mph down the road. Nice ride today, about 40F, my toes are numb though.|

|I don't have a solution for you but I thought it might help if you knew my experience. I'm on my third Campy group, one Veloce 8-speed, one Chorus 8-speed, and now Chorus 9-speed.
The Veloce rattled a little bit on rough roads but not enough to bother me. It stopped if I put my hands on the hoods. The Chorus 8 and 9 speeds have never rattled, ever.
And, yes, I've heard Shimano guys complain about the "Ultegra rattle" you mention. It seems to be normal.

|I have had Record 8 for a long time now. It started to rattle and drive me nuts. Turned out to be the small rubber bumper thingy inside the brake lever. It's designed to keep the two levers from hitting one another. Once mine wore down from shifting and weather, the two bang each other on every bump. Very very anoying. I ride over bumps with my index finger between there now. Until next week when my new Record 10 arrives! :-)|| |
