I noticed a "clunk" while pedaling in the BB of my Cannondale Synapse and the small chain ring on the front never really worked right. The bike had about 900 miles on it.
The LBS said that the BB bearings where "rilled" and were replaced free of charge on manufacturers warranty..... I also replaced the chain.
BUT after 70 miles I am noticing the SAME THING again and getting some bad front derailleur/chain rub in many gears including near the middle of the rear cog set??? (eg. 50/19)
What’s the deal?
