Transferring components to new Ti frame - A few questions..............

Hello,


Have not posted here for a few years. My current road ride is an 07 or 08 Rocky Mountain. I have an incoming 2011 Guru Praemio titanium frame that I plan to build up using all components from the Rocky Mountain. I have not ridden much the past few years so the Rocky Mountain probably has 2k miles or less on it. Full SRAM Rival components...... FSA Energy crank..... Ksyrium Elite wheelset...... components worth saving. I have a couple of questions......

1. Bottom Bracket: The existing RM frame (I think) has a 70mm bottom bracket shell width. The new bike has a 68mm width. The bottom bracket is an FSA BB-6000 or similar. Will this fit the slightly narrower shell on the new frame.

2. Headset: The RM has an FSA Intellaset Pro threadless headset. My plan is to try to remove and reuse. I have read up on how to remove with screwdrivers, etc..... Is it possible to use a pipe wrench with a rag to protect the headset and gently twist it out? Should I just fork over extra money and buy a new Headset for the new bike? FYI, I am reusing the Carbon fiber Columbus fork, so I can leave the crown race be if I reuse the headset.

3. Cables: Assume it is ok to transfer the cables as long as they fit ok. I am comfortable trimming them if needed. Bike has never been ridden in rain or bad weather.

Thanks all.


Nick

A little more research reveals that I may need a new headset. I believe the FSA Intellaset is integrated. The new Guru frame takes a non-integrated.

This is the fork:
Columbus Tusk Light Carbon Fork | Planet X

If I get a new Cane Creek 40 Headset, I assume this comes with the crown race?

1, add a 2 mm spacer to make up the difference between 68 & 70.

Bikes: '''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!

I'd be very surprised if the Rocky Mountain has a 70 mm bottom bracket shell width. That's almost exclusively used with Italian threading and very unlikely. Assuming it's English threaded it's either 68 mm for road frames or 73 mm for MTB frames.

Thanks. I did some random google searches looking for specs on my frame and stumbled onto a page that listed 70, so it is likely an error. I will go ahead and try to transfer the BB and see if I have any issues.

Just a heads up.....Use nickle based anti-seize on any metal-to-metal contact on Ti...It loves to gall.

Oil and grease can cause problems later.

Thanks for the tip. I am using a carbon seat tube currently. Other areas I can think of for metal to Ti are bottom bracket threads, headset and derailer connection?

And all of your bolts that thread into the frame.Stainless and Ti REALLY like each other if going that direction...

No wonder you did not find info on the bike - a random search would presumably yield random results. It has not occurred to you to simply measure the BB shell?

Don't tell me what "should" be - either it is, it isn't, or do something about it.

If you think I'm being blunt take it as a compliment - if I thought you were too weak to handle the truth or a strong opinion I would not bother.

Please respect others by taking the time to post clearly so we can answer quickly. All lowercase and multiple typos makes for a hard read. Thanks!

It did occur to me, but I didn't have a metric measuring device or calipers at home. The search was not so random, but the results were less than reliable.

Yeah, I've read that too but Litespeed's owner's manuals just recommended grease on any threaded fastener or component used with their frames and my experience with three Ti frame (I still have all three)
over 18 years of ownership and 150,000+ miles makes me think they are correct. I've used grease, anti-seize and teflon tape on bottom brackets for these frame and all worked equally well. I never had a fitting or bolt gall or bind anywhere.

That said, anti-seize is a fine choice and you can't go wrong using it but it is messy so wear old clothes while working with it.

Thanks all. I will get copper based anti-sieze as a precaution. I'm unlikely to remove items such as Bottom Bracket for a long time.

That makes the use of copious grease, anti-seize or teflon tape all the more important. The longer it's in place the more likely there will be problems when it's finally removed.
