Bike: Santana Team Scandium 7,900 miles.
Bottom Brackets 7,900 miles
Pedals Shimano SPD’s 7,900 miles
Wheelset Hadley Hubs 1,246 miles
Chain CN-7801 122 miles
Riding conditions 95% dry, we are near the coast so some sand on the roads.
The squeak has occurred on the last 2 long rides. Both times approximately 25 miles into the ride. Stoker hears it faintly for several miles before I can hear it. Sound goes with the cadence of the pedals, about once per revolution, only when we are putting a normal to heavy pressure on the drive chain. Sounds very similar to the wheel bearings failing on the original Sweet 16 Wheelset before the rear rim started cracking and I retired them.
What changed? Well I put a new chain on and the noise showed of soon after that. I did not oil the chain, normally let the factory grease protect the chain for several rides prior to cleaning and oiling.
What did I check? The first time it happened I stood up, no change; She stood, no change; Pedaled very lightly, noise stopped; Coasted, noise stopped
Got home removed all chains; Wheels spun freely, did not feel like bad bearings, cranks spin freely, did not feel like bad bearings, pedals were a little sluggish, but did not seem to be dragging, upper jockey wheel on the rear derailleur did not feel great
Next two morning short rides no problem. Today at the 25 mile mark, noise started again same as before.
Any suggestions? I really hate to just throw parts at it.
