So, Bike gets laid up for a week or so over Christmas

Headset bearing - seized, but moveable without too much force
Bottom Brack - rough
Wheel bearings - rough

I decide to completely strip the bike; clean thoroughly with degreaser and rebuild.

Luckily, when I built the bike, I covered everything in coppalip grease - so everything undid with relative ease, including the bottom bracket - I was surprised as I expected a fight with at least on component!

Anyway, ordered a new bottom bracket as the current one is too rough to be useable and managed to re-grease and free up the cartridge bearing in the headset (I don't want to have to replace this until summer as it is only going to get rained on in Jan/Feb/Mar)

The re-build last night went really well; lots of copper grease on all threads, quick to put back together...

Until......

I placed the carbon seatpost into the seatstay, set the torque wrench at 5nm and started to do up the bolt (the seatstay has a braze on seatclamp).

Clunk - bolt shears off in frame.....

Took the bike to Argos cycles in Bristol - they have now extracted the old bolt and replaced with a new one.

Moral of the tail is - coppaslip everything, if a bolt is 30 years + old, it will more than likely shear off under load - replace when you rebuild.

    Why was your bike in such a rough state after one week on inactivity?

    Not thoroughly cleaned after tons of rain and muck on the roads.

    BB and wheels has done approx 12k miles, headset has done about 8k miles......

    Also seen a crack in the seatstay where it meets the seat tube......will be back to Argos fro a re-braze and a re-paint in Feb.....

    Stored outside at work and ridden on fairly awful roads......the mileage and lack of maint has killed most bearings. Although with some TLC a fair bit has come back to life.

    That's the problem. Should have put it in th seat tube. The stays tend o be way too small ;)

    i rememeber years ago a water main burst by my house flooding the local cycle route (which is a disused railway track)

    the water proper flooded so i was dared to ride though on my Kona Stinky (downhill bike) i made it through but i was leaving an oil slick behind me from my suspension - it was that deep it was over my handlebars :shock:
