The Silex 9000 is a carbon gravel and adventure bike with Shimano's GRX825 Di2 electronic shifting in a wide-range 1x12 setup, a deep-section Reynolds Blacklabel ATR Expert carbon wheelset, an Easton EC90 AX carbon handlebar and a carbon seatpost. It's a high-end Silex build for riders who want crisp electronic shifting and a fast-rolling carbon wheelset on long, varied rides.
Gravel riding has gradually split into racing and adventure, and Merida's new Mission platform now takes care of racing. The Silex stays focused on the road less travelled, though it's no slouch: Matej Mohoric won the 2023 Gravel World Championships on it a week before it launched.
The Silex was designed from the ground up rather than adapted from a road or cyclocross bike. It starts from modern MTB-inspired geometry, with a long top tube, tall head tube and short stem, which gives nimble, confidence-inspiring handling on loose and rough surfaces. This second-generation frame also uses a revised fork design, so you can swap to a suspension fork without upsetting the geometry.
GRX825 hydraulic brakes with 180mm rotors provide strong, consistent stopping, and the flat-mount calipers sit on the chainstay on CNC-machined aluminium Disc Cooler fins that Merida says cut operating temperatures by up to 35%, which matters most when you're fully loaded. Five sets of bottle bosses, internal dropper routing and dynamo compatibility make it ready for bikepacking too.
