I have some take offs from a recently purchased Cervelo
Caledonia 105.

1. Cervelo Stem (Part # CS027) - 90mm, 8 degree pitch, swapped for a longer Zipp stem
2. Integrated stem computer (garmin and wahoo) and gopro center mounts
3. Handlebars - 40cm,swapped for Zipp bars

I had to swap for a longer stem during a bike fit so no longer
need these. Make a reasonable offer for all items and buyer
pays shipping. I can send detailed pics.
