zero offset vs forward seat post for roadie
Last year i rode my cross bike with aero bars for triathlons. I slammed the seat forward, and just made do. I am building up a road bike for next season and it will definatly get some triathlon use. Would it be better to go with a zero offset post for my TT/TRI use versus forward because it would be less of a shock to my muscles? It seems like quite a bit of a change to go to forward seat post if i am riding 1 TT per week (mondays), and probably 1 TRI a month in the summer, with 2-3 'road' rides/wk without aero bars sprinkled in there (along with some aero bar riding to prep for tri's)...
I hate buying things twice, but maybe start with 0 offset and move to forward if i feel i need it? (which i don't know what the indicators of this would be)

I have a forward seatpost (Nitto 66). I never raced it but I rode it around a couple of times. It definitely gets you forward. Other possibilities are made by Thomson, Easton, and Profile Designs. Before the forward seatpost, I would put on aero bars only for tris and move my seat as far forward as possible. It does lead to a shock on the muscles but mostly fatigues you in ways you are not used to. This lead to a lousy run leg. I was spent and my legs were not feeling it. I'll probably sell my nitto 66 (now that I got a tt bike). I think a zero offset would be more practical.

I do have experience with the aero bars, with the seat a bit forward (3-4cm) from last years tri (my first). Legs felt OK for the run (olympic distance), but i was slow, and had surgery on my ankle 2 weeks later. I think i'll start with zero offset first. I don't see reason to train 1/2 time in each of 2 different positions. Seems like id end up being a worse road rider, and worse TT rider this way. Or is it not that complicated?

It all depends on what is more important- your performance in the Triathlons or in the TTs. If you're only going to be riding aero once a week, I would pick one aero position and stick with it for a large chunk of time. Don't switch right before an important race- your muscles won't be used to it.
