Can I ride my Giant Talon 3 downhill? I have bought a Giant Talon 3 recently. I was wondering if it could possibly be used for the occasional trip to one of my local downhill tracks. I'm just getting started in downhill and so I really don't want to have to buy a new bike unless it is necessary. I was also wondering if it would be possible to put a longer travel fork on my bike. It currently has a 100mm travel Suntour fork on it, but I was considering putting a new fork on it with a travel of around 150mm on the bike. If I was to put a new fork on the bike what the would the maximum size really be for my bike (27.5 inch wheels, and a medium size frame)

More than likely - The occasional small jump won't hurt the Talon, but landing big jumps will require perfection (Those forks will make surviving a bad landing next to impossible).

We would need to know what the trails were, and how difficult they are, but if they have 'easy' trails that have chicken lines around anything that cannot be rolled over, the bike can be used.
