When you want a specialist trail bike, this is a good place to start.
Endeavour Cycles in Gymea has been operating for 20 years, providing services from bike-fitting to bike servicing to southern Sydneysiders. With bike brands including Cervélo, Pinarello, Specialized, Focus and ByK, it's a good place to come when you want to learn the difference between a $1000 road bike and a $9000 trail bike.
The shop also sells cycling equipment, like indoor smart bike trainers, car bike racks, and essential accessories like lights, helmets and locks. The store is also just a few train stops away from the Royal National Park, if you're planning to get your new wheels onto some trails ASAP.
