Thanks for the input. I belive I understand what I should do.
Here is my current situation:
1. Own weight (w/o gear) - ~87kg, i.e. ~191 pounds. I'll try to loose some in the spring. Way too circular shape these days
2. Static sag - 21mm
3. Race sag - 90-100mm depending on where I sit on the seat.
4. Current outside temp - -7 C (~21 F). First test ride is a good month or two away. It's not uncommon to get as low as -25 C (-13 F) in February.
Once again, thanks for the help, and I'll continue with my theoretical preparetion for the season.
