Hello RBR riders,

I have a 2004 Fuji Team Issue with FSA Gossamer Cranks. I have a problem with loud rattling noise in the crank during hard efforts in sprints and up hills. The shop where I purchased the bike check for cracks and leaks and untorqued and retorqed the bicycling and added an amazing amount of grease but the sound keeps coming back 1-2 rides later. Each ride after the fix it progressively gets louder till it reaches its original noise level again. Does anybody have any experience with this sort of problem or know about it. It sounds like I am stuck between a gear in the front derailleur kind of but its not that.

The bike is 64cm and I am 6'7" and 195lbs. I am also a former track and field all-american so the bike shop believes I am just too strong to keep the crankshaft from getting loose all the time. I don't know how true that is. :idea:

If you are talking about the non-drive side coming loose on you it seems that is a problem. FSA, reportedly is saying to use locktite on the threads. I had my fixing bolt come off my bike without warning, then my crank worked itself off the splines until I felt like I broke my chain, looked down, and the crank arm is hanging off my shoe.

I am now checking my crank for tightness on a regular basis and if the new one I have on there starts loosening up again, my bike shop told me to bring it in and they will swap it out with a Shimano crankset.

I've googled and found a number of boards where people are posting problems with their FSA cranksets, not just the Gossamer aluminum one, but even the carbon one.

I have a set of FSA carbon CSC Team Edition cranks that I installed on my Allez about 3 weeks ago. The first few rides were hell due to the crank bolts backing themselves out of the threads. I would get this audible "click" the further I would get into my ride. Freakin driving me crazy. I disassembled the cranks, retightened the BB cups and made sure that I bottomed out the crankarms against the spindle stops. Then applied green Loctite to the bolts and torqued per the spec. Since then perfection...I was going to buy Ultegra cranks but I wanted a bit more of the "bling factor". In retrospect, I should of stuck with the Shimano crankset, bombproof...Oh well.:mad2:

Bad Sound

I will try getting my team's sponsored bike shop to take a look at the problem and putting loctite on the crankshaft. I don't know the exact tools I would need to do it myself but I know that the sound is very annoying and embarrasing to have on a bike as expensive as mine. :idea:
