I just got Nashbar's Ascent Fluid trainer and put an old big-box store bike on it that nobody was using, so now I've got kind of a permanent trainer bike which is nice.
The problem: me and my partner are different heights/sizes, though close enough that all I really want to do is raise the seatpost when I ride, then adjust back down when I'm done.
Of course I need a new seatpost for this b/c it's too short to go any higher.
My question: is there a risk of damaging/wearing out the seatpost/tube quickly by adjusting it twice daily (once when I get on, then again when I get off)?
If so, what kind of lube (if that's suggested) should I use that won't have toxic/smelly fumes and be excessively messy/require wipedown every time I lower the seatpost?
I use park anti-sieze for my main ride, but that stuff is nasty/toxic so I don't leave any exposed (on the rare occasion I adjust height).
Should I just resign myself to eventually wearing out the seat tube and/or buying new cheapo seatposts once in a while?
