New frame - treatment?
Good day boys and girls.
Does anyone advocate: 1. Coating the inside of a new frame by swilling it out with any kind of gunk as a means of protection against corrosion? 2. Drilling a hole of some(?) diameter in the underside of the bottom bracket tube to allow it to dry out easily? Since all tubes have a small breathe hole somewhere (generally at their highest point) I'm surprised this isn't done by default, since any moisture in the frame will just gather down there. The frame is 853. I don't suppose these boutique tubes are particularly prone to corrosion anyway (am I right or wrong here?), but there seems no harm in trying to improve a good bike's longevity. Do any of you folks do anything like this? |

1. no 2. no. The lowest point is often not the bb shell and is actually the chain stay. check whether there is a hole there already. dont start drilling though. 3. You might want to consider getting the headtube and the bottom bracket faced as well as any disk mounts. |

Cheers Dave, Certainy not disputing what you say but I don't think I've ever seen a bike with frame tubes lower than the bottom bracket. this one certainly hasn't. Maybe I'm just unobservant... I've had the BB faced, but I bought the headset from the frame supplier so it kindly arrived ready to roll. I hope the head tube had been sorted beforehand. Looks pretty flush and true. I've never read anything about disk mount preparation, so don't understand what you mean in your final point. Do they need some sort of facing too? How is it done? Thanks again. |

might be wrong re the height, but my frame deffo has the drainage holes in the chainstay. Basically the two holes (assuming that it is IS mount) need to be parallel to the hub flange and flat relative to one another to ensure the caliper goes on square to the hub. The process is done using a milling machine and is best left to the pros. ie your lbs. |
