There has been an annoying squeak off the saddle for some time now. Yesterday riding with an acquaintance it really started to irk me. Last night after I got the kid to sleep I started by taking apart the bottom bracket and tightening to specification. No luck. Then I gave it a good night sleep. More of the same during daily nap so I tried tightening the stem bolts. Now I just took apart the whole chainset. Cleaned up everything and put it back together. Cleaned and lubed the chain. No change. I finally took off the Mavic Ksyrium Elite front wheel and exchanged to an older wheel. Magically no noise. What gives? I guess I just have to get the front wheel fixed every 1000km.
