Some pre-season maintenance on the fat bike today. Put a saddle on it that gets shared with a summer bike. Lowered the seatpost to summer shoe height as I don't need my boots yet. Unseized the front brake caliper and cleaned copper corrosion off the pads. Fiddled with the rear derailleur. Having the clutch turned on makes it more difficult to shift into the last few gears on my pie plate cassette, so I'll try leaving it off.
Tires didn't lose much air sitting idle since the start of March.
