Specialized Jynx Sport 650b Disc Womens Mountain Bike 2017
Stepping foot into the world of off-road/on-road versatility doesn’t mean you need to break the bank or opt for huge front suspension. The Specialized Jynx Sport 650b Disc Womens Mountain Bike 2017 comprises of durable and capable componentry to make your time in the countryside that bit more enjoyable. The carefully selected components mix a blend of performance with affordability, too.
The frame has been constructed with Specialized’s top of the line, lightweight and durable A1 Premium Aluminium that’s designed to go the distance. Twinned with Specialized’s Women’s Sport Trail 650b Geometry which provides a confidence inspiring, stable base for you to ride on over mixed terrain, whilst the SR Suntour 650b fork with 80mm of travel enhances comfort, too.
A wide range of gearing from Shimano Deore and Altus are welcomed when hills start to become challenging, and the Specialized Fast Trak Sport tyres offer great puncture protection and grip for a more enjoyable and reliable ride.
Features
- The frame was constructed from A1 Premium Aluminium, while the Women's Sport Trail 650b Geometry is on display in order to provide a confident, comfortable platform for riding over mixed terrain.
- Custom SR Suntour 650b suspension fork utilizes Specialized’s Multi-Circuit Damping technology to eliminate any "pogo" effect by delivering 80mm of hydraulic damped, coil-sprung suspension to smooth out rough terrain.
- A Shimano Alivio rear derailleur controls the rear shifting with durable aplomb. It shifts along a wide gear range, 11-34t, so you can ride confidently knowing that you'll always have the right gear for the hill at hand.
