Wade Posted March 24, 2019 Share Hi all I purchased a Fuel EX 9.9 in August last year. After about 2 months; a noise like a cracked frame started... I was assured it wasnt the frame. I have since spent R9 k on bearings and just about everything has been replaced, including BB, etc. I replaced the seat post the saddle... I am well within tolerance of the maximum weight allowance... Trek recently gave me a new frame... last a couple of weeks and the noise is back... Its driving me nuts! Anyone else had similar problems? Wade. Link to comment Share on other sites More sharing options...
BaGearA Posted March 24, 2019 Share Have it cleaned out and rebuilt by A reputable mechanic you've listed many of the most common causes for creaks so I think you will have found it on your own by now but i do want to ask if it comes out when you're hard on the pedals ? In or out of the saddle ? How much are you leaning/pulling on the handle bar ? IS it another generic nylon BB or something proper like Wheels MFG/Enduro that screws itself together within the shell ?

Me rida my bicycle Posted March 24, 2019 Share On dual suspension bikes it could be a dry pivot. In creaking frames grease is your friend. My bikes have grease everywhere from seatpost to axles. And since I do this I have no issues with noise. Not a lot just a thin layer. Dexter-morgan 1 Link to comment Share on other sites More sharing options...

Butterbean Posted March 24, 2019 Share Grease the freebody, the rear axle, pedal threads, between shoes and cleats, check the saddle rails aren't loose in the body, clean and grease headset and stem bolts, chainring bolts should be greased and tight, clean and grease seattube. There will be many more bits to check, clean, and grease, but try those first. Jako De Wet 1 Link to comment Share on other sites More sharing options...
Stevief Posted March 24, 2019 Share Wade I have a 9.8 ex. Had the same issue. Apparently the pivots needed to be greased . After I did that it was sorted. I was told that upon assembly overseas they do t really grease the pivots properly .Call the gearchange I. Cape Town and speak with Justin he will tell you exactly what to do. The fact that it is on both frames is a tad odd but I’m sure it’s the same issue. Link to comment Share on other sites More sharing options...
BikeisLife Posted March 25, 2019 Share Is it a creak or a knocking noise? If it’s a knocking noise and your shock is a fox Re:aktiv, that could be your problem. I had the same on my Top Fuel and had to send it to Omnico to get re-valved and the noise disappeared. If you have the receipt, they should cover it under warranty.

V18 Posted March 25, 2019 Share I think a gopro in the hand whilst riding on some smooth tar and closeup of all moving parts will help. I found my saddle rails were the issue. Really annoying. The other contender for sneaky sneaky click was chain ring bolts. Damn annoying Link to comment Share on other sites More sharing options...
Traveler Posted March 25, 2019 Share How did you spend R9k on MTB Bearings? Recently upgraded to SKF MTRX and got nowhere close to that. https://www.skf-mtrx.de/en PS. It can even be hub bearings Link to comment Share on other sites More sharing options...
Dexter-morgan Posted March 25, 2019 Share I had creaking on my Scott and it was suspension pivots, just cleaned and greased. Link to comment Share on other sites More sharing options...

love2fly Posted March 25, 2019 Share If this is a 1 x do not grease chainring bolts. They should be clean and loctited in place with removable loctite and torqued to the correct spec as they have been known to come loose. One should lightly grease the contact surface.Grease the freebody, the rear axle, pedal threads, between shoes and cleats, check the saddle rails aren't loose in the body, clean and grease headset and stem bolts, chainring bolts should be greased and tight, clean and grease seattube.There will be many more bits to check, clean, and grease, but try those first.

love2fly Posted March 25, 2019 Share I also ride road (for my sins), therefore when a noise starts I chase it incessantly...... On a MTB the greatest culprits are BB and pivots. I made the mistake of cleaning and greasing my pivots (different bike) and the noise would come back within a week or two.Now I clean but do NOT grease, leaving the bearings to do the work and only get the noise every 8 weeks or so when it is time to clean the pivots again...... Others in order of priority....Where stem and bars meet, seatpost and then axle contact surfaces ie where quick release and hub/frame make contact.Funnily enough I even got a noise out of my derailleur hanger assembly - clean and light grease....Good Luck!

Skinnyone Posted March 25, 2019 Share This is the issue with carbon frames...a small noise can and is amplified and "diverted" by the frame...so something like a pedal axle can sound like a headset making a noise... Kudos to Trek for replacing the frame - but I would start ruling other components out... I once had a client that had a creaky bike and was 100% sure it was the frame at fault as we had done everything - everytime i rode the bike after working on it, it was quiet, he rides it and it makes a noise within 10km of his ride...turns out it was his pedal/shoe/cleat interface was creaking, so when I rode the bike with normal shoes - no creak as soon as he got on and rode with cleats - creak...

Anyone else had similar problems? Wade.On my alloy Fuel EX I've had the following creaks: lower headset bearing, lower main pivot, dirty/under-torqued flip-chips & most recently loose-ish bottle cage mounts. Non-frame related bar-stem interface and pedal-crank interface are big ones. But the one that had me baffled for the longest was a Selle Italia's saddle rails creaking against the plastic saddle shell.
