Specialized Jynx 650b Disc Womens Mountain Bike 2017
If you want to break out of riding on the road and get out into the countryside and explore, then the Specialized Jynx 650b Disc Womens Mountain BIke 2017 is a great option. It incorporates a strong and durable frame that’ll go the distance alongside capable components that give you a taste of trail riding with a wide range of gears and suspension that’ll smooth out any bumps and vibrations from rocks and roots.
Specialized’s Women’s Sport Trail 650b Geometry 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.
The wide range of 16-gears is provided via Shimano’s Acera and Altus front and rear derailleurs. This level of shifting is perfect for a bike of this nature, giving you enough spin to get up tough hills whilst staying durable and virtually maintenance free.
Shimano BR-M375 mechanical disc brakes are ideal across a variety of conditions and thanks to their mechanical nature, they are easy to fix if anything goes wrong. Specialized’s Fast Trak Sport tyres further this durability, offering great puncture protection for a more reliable and enjoyable ride.
Features
- The frame was constructed from A1 Premium Aluminium, while Specialized’s Women's Sport Trail 650b Geometry is on display in order to provide a confident, comfortable platform for riding over mixed terrain.
- SR Suntour 650b fork features 80mm of hydraulic damped suspension travel to smooth out rough terrain.
- A Shimano Acera rear derailleur is built to with durability in mind, so you can rest assured that you'll have a reliable shifting partner for the long trails ahead.
