If you’re looking for your first step into the world of mountain biking, the Specialized Hardrock 650b Mountain Bike 2017 is an ideal starting point. Littered with performance driven components, such as an A1 Premium Aluminium frame and SR Suntour 650b 75mm fork, you’ll be climbing and descending with confidence, leaving you itching to take it to the next level.

Specialized Hardrock 650b Mountain Bike 2017

As the most affordable, yet high-performing mountain bike in the entire Specialized range, the Specialized Hardrock 650b Mountain Bike 2017 engulfs the countryside every weekend with discerning riders getting out there in the open and exploring. This bike is the ideal companion with capable components and a relaxed geometry.

Constructed from Specialized’s A1 Premium Aluminium, the Hardrock provides a lightweight, durable platform that can take on varied terrain with ease. The Sport Trail 650b Geometry is what sets this hardtail apart from the rest of the market, though. The geometry enables you to ride a bike that’s not just efficient in the climbs but conquers testing terrain that would otherwise leave you walking down the gradient.

Reliable V-brakes have also been incorporated to enhance confidence when the gradient gets steep, offering ample levels of stopping power to keep you safe. An SR Suntour 650b fork increases your performance on the trail, soaking up bumps and vibrations to ensure you’re as comfortable as possible. This fork provides 75mm of travel from a coil spring construction that’s highly reactive and adjusts to the terrain.

A wide range of gearing ensures you can adopt different riding styles, depending on your mood, and with the Shimano Tourney seven-speed rear derailleur, you can sit back and spin up the hills with ease, or attack the climbs and chase that elusive King of the Mountain.

All-in-all, the Specialized Hardrock 650b Mountain Bike 2017 has all the performance-driven components you need to get out into the countryside and explore. Whether that’s a relaxed Sunday ride with the family or an epic adventure with your friends, this mountain bike is a great stepping stone into the world of off-road riding.
