Ti tech question:(5 posts)

Ti tech question:4bykn
May 11, 2002 2:56 PM
I know that it is recommended to periodically disassemble and re-assemble components on a Ti frame, my question is how often? The seatpost is easy enough to do regularly, but my BB isn't in need of maintenance yet, should I pull it annually anyway? Also what of other bits: water bottle cage screws, clamp-on front derailleurs, headsets (which I lack the tools to remove), rear brakes, etc?
Thanks for any info/opinions.

I don't think there's any reason to take your bike apart on a regular basis. It's important to use anti-seize on the fasteners but other than that, just ride and enjoy.

Yeah, I agree, I wouldn't get obsessive about it. Things like BB's aren't going to last years and years anyway. Change 'em when you change 'em.

That said, a well-fitted Ti bike is a "lifetime" ride, so you don't want to go to change your headset 4 or 5 years from now and find it's bonded itself in place. I personally like to tear down my bikes about every 18 months, but that's just me liking to monkey. On Ti bikes, that includes popping the headsets for another dose of anti-seize. On all bikes, it gives you a chance to really clean and inspect things you normally can't/wouldn't, like headsets, come to think of it!

And I could be wrong about this, (I don't think I am) but I believe all watter bottle cage screws rest in alloy threads.

Long story short, grease can wash out, so why can't anti-seize? I find a year and a half to be a safe interval (essentially two seasons when I was in the Midwest), though I'd feel safe stretching that to 2 year gaps, provided everything was carefully anti-seized and assembled in the first place.

My LItespeed was new in Feb. '94. The original headset is in place, has never been touched. Kudos to Chris King. I've changed seatposts a couple of times over the years, as newer and cooler toys appeared, and I changed the b/b a year ago when I went to a Phil Woods. I've never had any problems whatever with any parts having seized. I use a moderate amount of grease or anti-seize when installing parts. So from my experience, I think the problem is vastly overrated.

I recently had to put the BB tool in a large bench vice and twist the frame to break things loose on a bike that had not been maintained for 4 years. It felt like it was close to breaking the lock ring, and it let go with a loud crack. I can't tell you whether the thing was well greased or anti-seized when put together, as it was not my bike. This reinforces the need to take things apart on some sort of regular basis if you want to get them apart when needed. I don't think this applies to head set cups, as I have not seen them bond to the frame like stems, seat posts, BB cups, bottle cage bolts, etc. I do my bikes annually and never have problems, so that suggests I could lengthen the period by some indeterminant amount of time. However, my annual tear-downs also reveal other problems that would not be obvious, so I consider them a reasonable investment of time. Your riding conditions, personal chemistry, and annual mileage come into play. I ride with a guy who sweats profusely, and his alloy parts seem to oxidize exponentially faster than mine. He had a steel frame replaced on warranty (rust through), while I rode one for a decade/50K miles and it never even showed rust under the paint chips.
