Just bought a used Six13 that needs a few things. I'm looking for the following:

1) C'dales dual-position seatpost, or failing that, a zero-setback seatpost. Lightly used. pref. 350 mm length. carbon.

2) 100 mm stem, standard diameter (i.e. not 31.8 mm oversized). preferably one w/ some negative rise to help me get a little lower.

3) Tri-specific saddle. Lightly used. Let me know what you've got. I like tie Fizik Arione Tri, the ISM, others.

Thanks!
