Quieting noises...nooblet's corner.

When I rode the Komodo on that 18mi swoopy pedaly ride, I was hearing some noises. Nothing drives me nutz more than foreign noises coming from a Chinese frame. I was hearing 3 seperate things.

1. once-twice per full crank rotation I was hearing an odd "tick" or "tack"
2. While I pedal, I would hear some "gear meshing" kinda stuff
3. Rear brake howl



#1. These are tough to track down sometimes. I cleaned my drivetrain, checked the torque on my crank bolts, BB, pedals, and chainrings. Still there. Seatpost needed a quick wipe and light coat of grease. **Noise Gone**

#2. This was fairly obvious...I checked my chain and it was just past .75% I usually don't replace anything on my drivetrain until it skips a tooth, but I had a nearly new chain that I took off for some reason in the past. I cleaned, lubed, and installed it. Quiet pedaling. **Noise Gone**

#3. Rear brake howl, hehehe. I've had some odd issues with brake noise, but this was nothing compared to the previous turkey warbling, shuddering issues that I had with the Juicy 5's and Code's on that old frame. Heck...brake noise and feel was the reason I ditched the old build and built the Komodo. When I lightly feather the brakes...they're fine. When I clamp down on them, they're fine. Somewhere in between with medium pressure...they howl like a typical disc howl. I've noticed an increased resonance with Avid G3 rotors. I had a nearly new Hayes 6" rotor, so I switched it out. So far problem solved...but I'll keep this updated. I think I'm gonna get a 7 or 8" Hayes rotor for the front too...though the front is quiet. I just think the Domain is sorta silly with a 6" I wouldn't mind a little more cooling up there too. Anyways...**Noise Gone**

Sound advice.


I only use grease on parts when I'm out of JB Weld and propane/O2.

Something I hadn't noticed...I think Hayes has updated their rotors. I don't recall the little holes drilled here and there around the slots.

Steel is real; purists use regular epoxy mixed with some of the steel dust from under their bench grinder.

Observant. New this year.


That was the result of a collaborative project that included wind tunnel tests at NASA's Ames Research Center in Sunnyvale, CA (the same place where they found that running a pickup without the tailgate actually creates more drag - - true story) and skid pad testing at Mazda Laguna Seca Raceway in Monterey, CA. They decided that it didn't help but it would look cool like the old dry lakes roadsters on El Mirage.
