Colnago Super maintenance question(4 posts)

Colnago Super maintenance questionCaseysdad

I'm seriously considering purchasing an '81 Colnago Super from a rider in my local riding group. It appears to be in excellent condition and the price is right, so...

My one remaining unresolved issue is that this particular model/year has a club-shaped (naturally) cutout on the bottom of the BB shell. I'm assuming that this is primarily for dranage purposes, correct? Unfortunately, given that it's large enough and positioned for optimal water escape, I'm thinking that it's also going to be prone to collecting water, dirt, small animals, etc. That being the case, what am I going to have to do in terms of day-to-day maintenance to make sure that this doesn't become a problem? Will it be necessary to pull the BB on a regular basis and perform a thorough cleaning of the shell? Is the BB likely to wear out faster given that it's probably going to be exposed to the elements to a larger degree than with most closed-shell designs?

Anybody here have experience with a comparable setup or other valuable insights? Thanks!

The thing with the cutout BB is that it will always dry out. Much preferable to sealed systems

You may find a plastic sleeve inside that serves to isolate moisture/grit from the bearings....if not, install one when you overhaul the BB.

If the frame is in "excellent condition" why not ask the owner. If after 20+ years his/her frame is still in such good shape than he/she would be the best person to ask for advise. Find out what they did and simply continue their maintenance schedule...
