Went to Mario Toledo to have my expensive RB serviced. I thought that it was due to for servicing since it has been 5 years since it was built.
You only need a 10 mm hex to remove the crank assembly (for Campy) But the difficulty was due to it being stuck and a lot of convincing (pounding softly) was needed. There were lots of mud at the spindle and the left bearing was busted.
This must have been caused by the 400 km bike to Bicol because the first 2 days was rained out.
So he advised that the crank bolt must be removed reinstalled periodically or that crank servicing will be made more frequent.
The rear wheel also had slight play. It turned out that an end cap needed tightening.
