Carbon seatposts likely produce the most vibration damping There have been at least two lab tests of vibration damping in seatposts. One, by Bike Radar, tested five brands of carbon seatposts. The second, by Velonews, tested 14 seatposts, including carbon, aluminum, and titanium. In addition, the Velonews test included one traditional suspension seatpost (i....

i always avoid aluminum fasteners wherever possible due to a lot of bad experiences with them disintegrating over time (especially nipples on fancy wheels), but i'm not a weight-weenie, just weight-conscious. i would say if you can afford ti bolts that'd be what i would go for, even though it's overkill and you'd be shaving maybe 1/10th of a gram. of course,...

Use retaining compound or just grease on the seatpost before the installation; this will prevent chemical reaction between dissimilar metals. There are titan-specific compounds for the job (see another answer), but regular grease reapplication during periodic (~once per year) bike maintenance will be as effective. From a "structural" point of view, there ...

Sorry to hear about your bike... Titanium anti seize is what you need. Park Tool makes one and you can usually find other brands of anti seize for a bit less at an automotive parts store but you may end up with a lifetime supply as bikes use very little.

In general, for weight weenie information, questions, and discussion, I'd recommend joining the Weight Weenies forum. The bottle cage bolts don't need to withstand impacts. They just need to hold the cage in place against the force you exert when pulling a bottle out. They don't really bear much of a load. I am not sure what torque specs there are aside ...

No doubt it's a little disappointing to have this hydraulic hose outside the BB shell if you were expecting fully concealed routing but what you have is the norm in a titanium frame. It looks like a lovely bike, I'm sure this small detail won't stop you enjoying the bike to the full! Looks to me like SRAM Force AXS chainset, with a threaded bottom bracket ...

Not all metal frames may be built with the hydraulic brake hose routing exiting the frame at the bottom bracket. In principle, with an oversize BB, e.g. a T47 threaded or a PF30 press-fit, there could be sufficient room to route the hose through the bottom bracket shell around a 29-30mm spindle. Per this post on the Weightweenies forum, some titanium frame ...

Titanium is light, strong, and like aluminum, is corrosion resistant by virtue of the formation of an inert oxide layer on the outside. As long as this oxide layer remains intact, a titanium part is very corrosion resistant and will not react to other metals. Thus, grease applied to the titanium threads will prevent galling, which will expose the reactive ...

@peter If you use locktite make sure you DO NOT USE red. Use the blue.
