New Frame Prep & headset /BB inst...(8 posts)

New Frame Prep & headset /BB inst...6was9

installation question.

I am getting a Look Carbon frame and a Chuck's $75 Kenesis made Al frame for mainly trainer usage. Will be installing Chorus and Centaur group respectively.

I would expect Chuck's frame to be raw. As for Look I don't know(comes w/intergrated headset preinstalled.) How should I prep/ face/ chase these frames? How do you face a CF frame? Should I have LBS prep/ face only? How difficult is it install BB and headset? I am concerned about some of the LBS though. For example, as I was pricing the cost this one Trek/ Raleigh dealer lbs didn't know what Chorus was!?

I understand that the cost of the tools for facing and cutting makes it impractical to purchase them. How about installation and removal tools?

Thanks in advance.

There is no prep to do on the Look Carbon frames. The bottom bracket is already to go as is the headtube.

The BB will need to be cleaned. I used some wd40 and a rag to get all the dust out, not that there was very much. Normally the look frames have plastic caps over the headtube. Once you remove them you will see that everything is clean and ready for the bearing/fork install.

Have fun building. Look frames build up very easy.

Read up on these subjects at The BB installation is a piece of cake. All you need is the campy splined BB/cassette lockring tool, which only costs $10-15, maybe less. Just remember that the drive side has left hand threads, assuming both frames have english BB (I know LOOK does).

Centaur require an entirely different tool for BB installation. If I was buying, I would upgrade the Centaur group to a Chorus crank and BB and avoid buying more ttol just to install a cheap Centaur BB. 2003 Chorus is on closeout at many places at significantly reduced prices.

I always carefully scrap the paint from the face of the BB on the drive side. Never bought a frame that needed facing.

... is to keep the Centaur crank and get a Record track BB, see for compatibility details. This will probably be cheaper than upgrading both the crank & BB, will install with the same tool, and be a much higher quality BB than the Centaur.
this BB has no seals....C-40

The track bottom bracket would not be good for general road use, since it does not have seals to keep water out.

What do you do about the paint over-spray inside/ on the BB threads?

Also Park's Centaur BB tool(BBT-4) only costs $7.95; how better would Chorus BB/crank be for a trainer bike?

I usually have the LBS chase the BB, install the HS cups and flanged nut in the fork. The rest i do myself.
