Notices
Road Cycling It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle. -- Ernest Hemingway

SRAM Force shifting - what should it sound like?

I have a carbon frame bike with SRAM Force shifters and derailleurs that I have had for about a year now. This was my first bike with brake lever shifters, so I had nothing to compare it to other that my 7 speed down tube Shimano 105 setup. Overall I have been happy with the shifting performance but one thing has always bothered me. When I'm riding with friends on similar (mainly Shimano) bikes I notice that when they shift the rear derailleur I hear a distinct "thunk" sound. When I shift on my bike I don't hear this. Is this a SRAM thing? Or do I have something setup wrong?

I would definitely get this checked, my SRAM sounds like "thunk-kink!".

It sounds like a manual cash register. Even though I have it on two of my bikes, I don't care for it.

it should go click-chank... or click-chunk (if you have a Shimano cassette), any other noise is cause for a warranty claim.

My SRAM is louder and i can feel the shifts better than when i had shimano. They may sound louder depending on what angle your friends are from your ears.

To OP: Does your bike shift correctly? Meaning finding the gear with out hesitating both on the way up and down?

Click - clack - ping - bang - clunk = SRAM drivetrain is shifting correctly
Smooth and quiet = Something is definitely wrong

Loud and obnoxious. I have been on it for 3 seasons and can't wait to get back to Shimano.

Let your rivals know you're coming. Being quiet and stealthy is just cowardly.

I'm glad I have Campy. Nice and quiet but distinct clicks in the levers.

My TT bike with Red has a loud "ka-chunk, shhh" shift to chain movement and then when I get to above 100rpm "RRRRRRR" from the Red cassette a la disc wheel. Love it!

But there was one time a mechanic mistakenly adjusted the bike and the bike turned all Dura Ace on me, sound wise. Shifting became slack and everything became "slippery". Luckily got readjusted at a more competent mechanic and all the normal SRAM sounds came back.

2012 Red.

It seems to me that most of the noise on a SRAM drivetrain is up front in the shifters, versus the actual derailleur itself.

Are we still trying to 'fix' a bike that shifts correctly but not noisy enough?

Thanks for all the replies - some of the sound descriptions were very creative! I think I like Psimet's the best.

To answer the question of fixing something that is not broken. My problem is that my basis for comparison is Shimano 105 from the late 1980's. Yes it was indexed, but it was down tube shift levers. Subjectively, I have always wondered if my SRAM Force is shifting a little slow - especially on up shifts. Maybe I need to see if one of my friends has SRAM Force (or any SRAM for that matter) and ask them to let me try shifting to see if it feels any different than mine. I guess I was assuming that the "thunk" noise indicates a more positive and perhaps faster shift.

At the risk of starting another Shimano vs. SRAM thread, here are my observations on how SRAM double-tap works.

When downshifting to a larger cog (increasing cable tension) the actual shift occurs after the first click as you continue pressure on the shift lever to the second click.

When up shifting to smaller cog (reducing cable tension) the actual shift occurs after the click as you release the shift lever.

All this to say that for up shifts, any resistance in the cable, shift lever or derailleur will slow the shift. Perhaps I have some resistance somewhere in the path that is slowing the shift a little. As I said, functionally the shifting seems OK as it doesn't skip or miss a shift. It just feels like it could be a little more crisp, especially on up shifts.

Downshifts appear to be more affected by how much pressure I put on the shift lever. Presumably, because cable tension has to be increased to actually make the shift happen.
