Gravel Bike Mechanics for Girona
The gravel routes around Girona mix smooth tarmac with rocky Pyrenean dirt tracks, loose limestone descents, and olive grove two-tracks. Your bike must be set up to handle all surfaces reliably, and your repair kit must cover multi-hour remote sections.

Select and Set Up Tires
Description: Run 40 to 45mm tubeless tires with a file tread for mixed surfaces. Use 25 to 30ml of sealant per tire. Check pressure before every ride: 28 to 35 PSI depending on rider weight and terrain.
Optimize Gearing
Description: For the climbs toward Les Gavarres and the Rocacorba area, a 40 or 38 tooth front ring with an 11-42 cassette is optimal. Confirm derailleur hanger alignment before long rides.
Build Your Repair Kit
Description: Carry two CO2 cartridges or a mini pump, a tire plug kit, a multi-tool with chain breaker, two quick links, a spare derailleur hanger, and a small bottle of chain lube. Pack in a frame bag or saddlebag.
Pre-Ride Mechanic Checklist
Tires: check pressure and inspect sidewalls for cuts
Sealant: shake wheels and listen for liquid movement
Chain: clean and lubricate, check for wear with a chain checker
Brakes: squeeze test and inspect pad wear
Bolts: check saddle, stem, and bar end bolt torque
Confirm repair kit is in saddlebag and CO2 cartridges are full
Carry a printed or downloaded offline map for the Gavarres routes. Mobile signal is unreliable in the forest sections, and GPS tracks on a head unit can fail without a backup.
